Mirror SCSI RAID array to SATA disk?

Q: Mirror SCSI RAID array to SATA disk?

I'm just wondering... I'm setting up a server and planning on having either a RAID0 or a RAID5 array of SCSI disks.

I could potentially use a SCSI RAID1+0 setup for my backup needs, but I've been thinking along different lines. My system drive/array will be around 300 to 450GB in SCSI, and I'm planning on having a large capacity sata disk or two in RAID1 for data...

... while I know I probably can't use the same controllers, is there any cheap and easy way by which I could have the system drive (scsi striped array) mirrored to a dedicated sata drive for backup purposes, such that if I lose the whole striped array at some point, I'll still have a backup of the lost data with which to build a new array to replace it with?

A: Mirror SCSI RAID array to SATA disk?

The good thing about Raid 5 is if one disk starts to die it gives you warning and time to pull it out and rebuild it without missing a lick. If the controller goes you can replace it and your drives will still be fine.

Now if you want to back up your entire network to a SATA array then i would advise investigating Data Protection Manager 2010 (DPM 2010). Full backup to a disk array every day and incremementals every 15 minutes, then a tape backup to take to the bank on the weekend.

Is it possible to setup a mirror array with an internal drive and an external drive setup with esata? The main reasoning behind this is that I want to make a backup of one of my internal drives. The internal drive is 1.5TB made into two partitions, one 500 and ext3 and one 1000 and ntfs and the external is 750GB ntfs (I could format it to ext3) with no partitions. They use the same sata controller, so I can set it up in the bios as a mirror array.

I've done some research into it and it looks like it could work, but still want to be sure that there will be no problems.. My external drive is a little slower than my internal simply because it is slower to spin up in general. Would this slow things down as it waits for it? Or will it just rely on the one drive until the external is working? Do I need to do any setting up other than in the bios? I'm using Ubuntu 9.04.

Am I better off just using a backup program?

Sorry for all the questions, it'd be great if this could work instead of relying on just doing a backup every now and then.

I've got a computer with three physical hard drives. One is an old IDE drive that we use for a scatch disk for PhotoShop work. The other two are identical SATA drives in a mirrored RAID array, which is where the OS is supposed to be installed.

The computer was previously running Windows 2000, but I wanted to upgrade to XP and decided to do a fresh install this morning.

During setup, I did the F6 thing to install extra disk controllers. When I got to the setup screen to choose what drive/partition to install Windows on, the IDE drive *and* the RAID array showed up. The RAID array had several partitions, and I deleted a couple of them, including the system partition. In other words, I'm past the point of no return.

When I chose one of the partitions on the RAID array to install Windows onto, I got the following error message:

To install Windows XP on the partition you selected, Setup must write some startup files to the following disk:

58644 MB Disk 0 at Id 0 on bus 0 on atapi [MBR] (That's the IDE drive)

However, this disk does not contain a Windows XP-compatible partition.

To continue installing Windows XP, return to the partition selection screen and create a Windows XP-compatible partition on the disk above. If there is no free space on the disk, delete an existing partition, and then create a new one.Click to expand...

I don't care to have an extra partition on the IDE drive, and besides, I want to be able to boot without the IDE drive anyway.... Read more

It sounds like my hdd is about to die and i wanted to create a raid array (using my mboards sata) by installing a new hdd to backup before i lose everything. Can I do this? will i lose everything on my existing hdd? What is the best option. I am running winxp pro

A:p4p800 sata raid array

If the drive is already failing, a RAID setup at this point would be a bad idea. Your first priority should be to backup all the important data you have.

Once you have done that, getting a replacement drive would be a good idea. and perhaps two discs for a mirrored array would be in order.

I do not know if the onboard raid controller for the P4P800 would let you take an existing drive and convert it to a mirror disk without losing any data, but it may be able to.

I have just bought two brand new WD 500 GB RE4 HDD's and connected them coorectly for RAID 1.
I have changed the BIOS and Pressed Ctrl+F to create the RAID and this has been successful.
When installing Windows you obviously get to the aprt where you need to load the floppy drivers to locate the drives...

I have downloaded ever driver from the Gigabyte support drive and loaded them onto a USB, not one driver can be seen when the USB is "Browsed" too...

How important is it that the drivers are on a floppy, as I do not have a floppy drive or access to a floppy and drives.

Also what driver should be downloading as I tried the 3.2.1540.17 one and that was not seen, so I just downloaded them all in an attempt for success.

Any one with any advice its greatly welcomes thank you in advance

Hi everyone.

Going crazy with this. So about 2 weeks ago, my "intel rapid storage technology" software gave me an error. I opened it and saw that one of the disks (2 disk array) in my Raid 0 array, had an error. I reset it back to normal and left it. Then I started to get pop ups saying that files were corrupt over the course of the next few days. My OS still worked and everything worked as usual, except my sound card. I have no more sound from anything plugged into the jacks, only USB connected audio works.

So, I attempted to run a check disk to fix said errors, but I get a message that the drive is not accessible due to a recent software package install "error 766f6c756d652e63 3f1". I went into my system restore and all restore points are gone, except one. When I click on it, it says the drive is not accessible.

Today, I installed 2 new 1TB hybrid drives in another Raid 0 volume (yes I know...but that's what I am using for now). When I went to write the system image, it said the disk had errors and to run a check disk first......which I can not.. I clicked ignore and let it go and write the system image with the errors. When it is done, do you think that I will be able to run a check disk on the new drives (2nd array, since it will not be inaccessible) to repair the errors that it wrote from the bad disk?

I am not sure where to go from here. My PC is still up and running and almost finished copying the image to the two new drives. My hopes are th... Read more

Hi all,

I have a Dell Dimension 8300 with a WD 200G SATA drive and I'm trying to format and install a fresh copy of Windows XP Pro SP2. I have made an image of the partition C: with Norton Ghost 8.0 before I went on with the formatting.

Problem: After the installation of Win XP, it is extremely slow. As I scroll through the screen (especially when using IE), I could see the screen try to refresh from the bottom to top).

I've installed the Intel Chipset Utility and the Display driver (nVidia 66.93) but it's no help. Before as I was installing Windows, I performed the F6 procedure and installed the Promise SATA Controller from Dell for my Dimension 8300. but it still not working.

After that, I followed the instruction from the Dell's website and tried to manually update the SATA Controller in Windows by going to Device Manager --> SCSI and RAID controller, except there was NO SCSI and RAID controller listed in there!

So I decided to load the original C: partition from the Ghost image to see what's there for the SCSI and RAID controller, it's merely using the A347SCSI SCSI Controller from Microsoft and it does not have the slowdown problem at all.

A:Need to format a disk with errors in a RAID 0 array

You cannot mark bad sectors on one drive in a RAID array. Your RAID controller should be smart enough to mark the whole RAID stripe bad. Check the RAID setup program for some initialise or check function. You may lose all your data though. Didn't anyone tell you that RAID0 is bad for data integrity?

If your drive is still under warranty and it has bad sectors then you can have it replaced of course. But again, you will lose your RAID contents

I have two 500Gb SATA drives in a RAID 0 config set as my system drive 'C', and a 1TB SATA as a storage drive 'E'

Never had this problem until last night when I removed the storage drive. Tried the usual fixes with no luck, put the drive back in and the system boots normally.

The problem seems to be that I installed Windows on the RAID array while the storage drive was attached, and for some reason Windows decided to make 'E' the active partition.

Have attached a screenshot.

'E' also shows as System for some reason, even tho Windows is on 'C'.

What I want to know is can I fix this problem without reformatting/reinstalling, and what will potentially happen if I make the 'C' partition active? Dont really want to kill my machine right now!

All comments and advice appreicated.

No problem. First, mark the Windows partition as active.

I have two 1TB disk drives as storage space. Originally, I set these up as a RAID 1 array, but am now using this PC for DVR purposes and not so much for actual work, so the disk space is more valuable than the redundancy. So I wanted to undo the RAID, but the RAID is not my boot disk, so I figure it would be a piece of cake. I backed everything important up onto an external USB drive and got to work.

I originally created the RAID array using the Intel Rapid Storage Storage Technology software, so I figured that was a good place to start. However, at this point the software wont open. I tried uninstalling it, but when I try to reinstall, I get an error about not working in this 'environment'. After a bit of unsuccessful troubleshooting, I decide to skip on the Intel software and work with the windows Computer Management / Disk Management bit.

In there I find both physical disks listed, but one is inactive indicating that there's a "device signature conflict". I used the command-line fixer thing to bring the disk back online, so now Windows sees two independent drives. So far, so good.

When I start moving things around, I get a BSOD within 5 minutes, and it keeps happening.
All I can see on the BSOD screen is "QL not less or equal..." But it is appears to be somewhat cut off by the tv/monitor.

So I figure maybe that DVR-destined drive went bad since that was the one under heavy load when the BSOD started, and I remove it from the system. Everyth... Read more

I had to identical 80GB Seagate SATA drives set up as a Raid, don't remember the number but they were a mirror of each other and Win XP Pro was on them, one was drive C and the start up. They were drives 3 & 4 in BIOS I had 2 IDE drives as 1 & 2. MOBO is ASUS P4C800-E Deluxe. Something failed on drive C, set BIOS to non RAID connected the mirror drive I believe that it was designated J changing the drive letter to C so the registry would still function. Some things still see that drive as J most don't including the system hardware.

I would like to put the drive back in the system, but each time I reconnect it the system either fails to start or takes 20 minutes to start and then nothing works correctly or spontaneous. I suspect that the system is seeing both drives as C and therefor goes nuts trying to figure out which one is the real C drive.

I have since installed Win 7 on a logical portion of one of the other drives. I have not tried to connect that drive using Win 7.

Hi there,

I have got two SCSI hard disk arrays running in my server, one is a 3-disks array on RAID-5 and the other one is a 1-disk unRAIDed.

Both arrays are presently holding data.

I want to install another 2 SCSI disks on the second array so that I can RAID these 2 together with the existing 1 on a RAID 5.

Can someone please kindly give me a walkthrough how to do it, because apart from changing hard disks on a PC, I have never done anything with SCSI hard disks before.

Is there any issue with data migration?
Do I have to temporarily transfer the data in the disk to another storage, install the 2 new disks, RAID the three together, then transfer back the data?
Or can I just simply plug in the two new disks, and RAID the three together, without having to worry about the data contained?

Ascan be seen I am in very very desperate need for help here.
So from the time the new disks arrive, what do I have to do?

Thanks so much. Any input is very much welcome and appreciated.

A:How to add SCSI hard disk to RAID

I am not sure I completely understand what you want to do. I think you want to install two new drives onto a scsi card and then create a raid array on those two disks.

As long as the scsi controller you are connecting these to supports raid, it should be no problem. Shut down and connect your drive to the controller. The one disk connected now will have the terminator jumper / plug installed on it. This needs to go on the last device in the chain. Now restart and enter the bios for the controller you are setting up the raid array on. There are different key combos for different card mgf's so you need to know which key to hit. When in the raid bios, select the two disks you want to create the array and start the creation process.

I am assuming that the os is already installed on another device and that drivers for the raid card are already installed. Go to disk management and you will need to partition and format your array. You MAY need to restart after you partition the array. Format with ntfs and you are good to go.

Hi Everyone,

I have just cloned a RAID array and I am concerned about it's performance.

A bit of background...

My Motherboard = ASUS Z9PE-D16
RAID Card = PIKE 2008 LSISAS RAID card

The initial RAID array consisted of 6 x 1TB Seagate Constellation (ST1000NM001) SAS drives in a RAID1+0 (10) configuration.

The new array consists of 6 x 4TB WD SATA drives in a RAID1+0 (10) configuration.

Initial performance is quite slow, but this may just be due to parity checking. On paper the original, and new drives are comparable.

Whilst the original drives were SAS and the new drives are SATA they both operate at 7200RPM and have 6Gbps interfaces.

My question is - "Is my initial slow performance likely due to parity checking, or will I experience ongoing slowness?"

Any help here will be greatly appreciated. Furthermore whatever you offer with regard to help may assist a piece of Australian Cultural heritage!

Started with Windows and apps successfully running on Disk 0 (1TB Seagate). Bought an exact duplicate HDD, recognized as Disk 1. Followed instructions and used Windows Disk Manager to convert Disk 0 to Dynamic, and configured as a mirror with Disk 1. Everything still worked perfectly. Physically disconnected Disk 0 to test booting from the Disk 1 mirror. Boot failed, and upon reconnecting Disk 0, the PC rebooted (from Disk 0), but mirror was broken.

THEN, my error, instead of properly re-establishing the mirror, I "imported" Disk 1. PC still boots (from Disk 0), but now Disk 1 appears with a drive letter, and Disk Manager does not offer the option to break nor re-establish the mirror. What steps must I take to re-establish the mirror?

I have a computer running XP which was built with a pair of 80 GB hard drives which have met their limit in terms of free space so the user is wanting to upgrade. These drives appear to be running in some kind of RAID setup via the motherboards built in RAID feature (not a PCI card running this setup). This is the first time I've encountered a RAID setup in a home-based PC.

One other minor problem I have is this motherboard (an Asus ABN-VM) only has two SATA ports, which are both used, so I'm going to have to clone to an external drive as an image file and then connect the new single 500 GB drive and clone back from that image to the new drive. However, come to think of it, I have an adapter that would allow me to connect the new drive to the PC via USB so... scratch that concern I guess.

I decided to take the plunge and see what Clonezilla would do with the external USB drive I have and the two 80 GB drives in the PC. When the main menu appeared I told it that I wanted to work in device_to_image mode and then told it to mount all drives. It then asked me to select the drive I wanted to use as the source but it presented both drives as individual drives, not a single mirror as I was expecting the motherboard to present it as. So... don't know what to do from here.

Perhaps there's another cloning utility out there I could run from within Windows or could boot from a disc that would recognize this array and clone it to a single drive properly. Any suggest... Read more

Hi all,
My RAID 1 (I think? I have two equal drives that are mirrored) array was causing me a lot of pain. It kept freezing up my system and having me to had to rebuild the RAID too often. After a number of tests and browsing info online, I've decided that the RAID was the culprit of the freezing and BSODs that came once in a while.

Before deleting the RAID array, I went and used the Seagate (my HDDs) .iso file and used their diagnostic tool to check the drives. I did a long test of one of the HDD (Device 1) and it passed. I deduced that this was at least a good drive. I didn't do a long test for the other HDD (Device 0). But with both, after a short test, both passed.

I then went into the RAID manager (DOS-looking screen before Windows starts) and then 'reverted' Device 1 to non-raid. Then decided to choose 'delete RAID setup' for the Device 0. All good so far. I rebooted and Windows actually started fine. This is where I'm at right now as I type this. No freezing so far!!!

What I wanted to know is how do I find out which HDD Windows is booting off from? Is there a command line I can use in command prompt window in DOS mode to find out this info? It'd be great to know that I'm not on Device 0 since I haven't done a Seagate diagnostic long test on that one.

Also, I'd ideally want to have the second (Device 0) HDD formatted so that I can leave it in my tower and use it as an external HDD with Syncback. This is the closest thing I can have to RAID and I'm perfectly happy ... Read more

A:RAID - deleted RAID array, Windows 7 ok but I have questions

You can do into Disk Management and it will tell you which drive is used for booting. It will say it is active.

I am confused as to one part. You say you want to leave the second drive in your computer, but use it as an external. You can use one as your main drive, and use the other for backup...however a good backup process involves a drive that isn't readily available all the time. That being said, something like SyncToy from Microsoft will allow you to choose folders and on a schedule or manually, copy them to the second drive. I use this on my wife's laptop to keep her photos backed up to our server.

RAID has no place on a desktop system, so you are better off without it. But to get started, just go into Disk Management to see how your drives are configured now. Post a screenshot if need be.

It was on the Intel Matrix Storage Manager before Windows started, one of the physical disks were listed in red. However, the computer was still in full working order, but I wanted to get rid of the screen that kept coming up, so in an attempt to fix it, I went into the Matrix Storage Manager's configuration utility and not knowing what it would do, reset the disk listed in red to Non-Raid.

I am thinking to renew the whole data in current raid1 array md0. My environment is:

raiddev /dev/md0
raid-level 1
persistent-superblock 0
chunk-size 16
nr-raid-disks 2
nr-spare-disks 0
device /dev/hdb1
raid-disk 0
device /dev/hdd1
raid-disk 1

this '/dev/md0' is /home, so I'm not booting from this disk and the other file systems including root and /boot are on /dev/hda.

What I want to do is to renew the whole data in /home.

Is there any way to do this by switching /dev/hdd1 with all new data copied, then sync this new data to the other raid disk (/dev/hdb1) : FROM /dev/hdd1 (the disk just added with new data) TO /dev/hdb1 (currently active raid disk)??

Usually, after switching the HDD to new one, data in /dev/hdb1 is to be copied to /dev/hdd1 for recovery. But in my case, I want to do the opposite.

I would be so appreciated by all your helps,
Thank you,

A:RAID question: how can I renew the data in raid array?

I'm not sure what you want to do.. You want to copy something to the /dev/hdd disk (from another computer maybe) and then copy the data from /dev/hdd to the RAID array?

Since you are using RAID1 then it should be fairly simple.
You just simulate disk failure by removing /dev/hdd. You could do this by making the hdd drive hdc instead (jumper it to be the secondary master). Now you mount the "hdc" drive (that really was you hdd) and copy whatever you want to /dev/md0.
Since it's a RAID1 array then all the data that goes to md0 is written to hdb and when the /dev/hdd comes back the RAID is syned onto both disks again.

I'm not sure if that makes any sense to you. Can't be less obscure than your post though

Just wanted to post this to the internet since there are literally no other posts about this exact scenario, which I could see others running into. Short story - I lost 2 drives in a 4-drive parity array.

I had a shotty storage spaces array in my home desktop comprising of 2x2TB WD Green drives, 1x2.5TB Seagate Green, and a 2TB WD Red in a Storage Spaces array. A small mirror volume spreading all 4 drives was created first, which would host my critical files (this array never failed, by design), and a parity array that filled the remaining capacity, which also spread across 4 drives. I ran in this configuration for over a year before experiencing hardware failures.

First off - Never run green drives. I don't care your reasons for wanting to buy them or receive them for free (sell them if you do), but I've lost several dozen green drives over the last few years. They will fail! They're bottom bin drives that didn't make the cut.

I upgraded my computer case (Cooler Master's HAF XB Evo Lan Box is incredible and worth every penny), and while doing so, accidentally dropped two powered-off green drives about 3" onto a soft surface. I can only deduce that this is what caused the drives that worked pre-case-upgrade to fail. Upon booting the system back up, Storage Spaces started throwing notification errors at me that 1 drives was missing. So I hopped into powershell and ran get-physicaldisk, and one of the drives wasn't showing up in the list. After some quick troubleshooti... Read more

Ok, some time ago, I bought a server from a corporate reseller. It came with 3 SCSI drives installed. I broke out that copy of Server 2k that's been collecting dust on my bookshelf, got it loaded and away I went.

I recently got a good deal on replacement drives for the box... This will almost triple my capacity. The drives are set up in RAID 5. I have yet to run across a solution that will allow me to clone the current array to the new array.
I currently have 6 drives installed (max capacity), 3 per array in RAID 5. As soon as I can get the system migrated to the new array, I plan to remove the old disks and replace them with 3 more of the new drives.

can anyone suggest a software solution that will let me clone the arrays?

At the moment my system is set up with a bootable 3 disk SATA RAID 5 array via the SIL3114 ports. I am trying to:

FIRSTLY add a new SATA hard disk to the Nforce4 SATA ports as a non-raid drive which I want to make the system's BOOT disk and make the existing RAID 5 array non-bootable.

SECONDLY add 2 new SATA drives in a RAID1 array via the NFORCE4 chip.
I have added the non-raid HD to the nforce4 sata ports and set the appropriate BIOS RAID setting for the single HD to disabled. This has enabled me to migrate boot files etc onto the new disk. I cannot however get the system to boot from this new non-RAID hard disk as it does not appear under the BIOS Hard disk boot setting - instead it boots with the Sil31114 SATA RAID 5 array. The only way to get the new hard disk onto the Hard disk boot list in the BIOS is to disable the BIOS IDE/SATA RAID setting completely. If I do this however it will not allow me to add a further RAID1 array to the nVRAID controller.


Thanks very much

Hey guys,

I have another idea for a general discussion based on one project I have taken on at work.

Each department at my work has their own budget for expansion, IT needs, etc.. So I have one workgroup which uses a NT4 Server which greatly needed more storage space. They currently have a SCSI array, and when confronted with the cost of expanding the SCSI enviroment all hopes were lost. Quite simply too expensive.

So.. not to cut my depeartment workers short of thier needs, I quickly set out to find another solution. I stumbled upon an IDE ATA 133 RAID controller card. After doing the math, I figured I could give the department 40gigs of mirrored storage (40 x 2) for less than the cost of a single 18.4gig SCSI HD (keep in mind you would need two of these).

I notice that the IDE RAID array does not read quite as fast, but being that this is only a workgroup server and not an enterprise server it is not really a problem.

I have been playing with the IDE RAID array to test the rebuild capabilities, error detection and correction, flexibility, etc.. and the setup has passed with flying colors.

I would like to hear about anyones expiriences with this type of setup, or thoughts.

I'd also like to find out what the actual difference in read time is between SCSI and ATA 100 / ATA 133 arrays.

Let me know what you think.. Want a link to an IDE RAID Controller Card? Only $40! Controlls 4 IDE devices!

A:General Discussion: IDE RAID vs. SCSI RAID

IDE raid is an attractive option for folks not needing the high-end capabilities of SCSI drives, and speeds are certainly getting better with IDE drives, though not nearly as fast at 15K RPM Ultra-320 SCSI drives. One thing that will improve your array, add one more drive. You'll get the RAID redundancy, but much faster access, reading and writing. With mirroring, writing is actually slower than a single drive, and reading is basically a single drive. With RAID-5, requiring at least three drives, reading and writing will be faster than a single drive.

I installed Win 7 Ultimate on my system and it has two disk drives.

When Win 7 was setup, it partitioned Disk 0 as:
100MB for "System"
The rest for C: (incl. boot, page file, crash dump)

The machine is working fine. But now I want to mirror Disk 0 in case it ever crashes. So I plan to setup Disk 1 to mirror Disk 0.

So I change Disk 0 to a Dynamic disk and then add a mirror on Disk 1. To my surprise, it grabbed a hunk of Disk 1 and mirrored C:. But it didn't mirror the 100MB System.

Well...that's no good - if Disk 0 dies, I want to be able to boot off Disk 1, put in a new disk, resync, and be back in business with a minimum of fuss.

When I click on the System partition and say "Add Mirror", it asks me to select a disk. I select Disk 1 and it gives the error "No extents were found for the plex".

Here is what my disks look like now:

How can I have Disk 1 be a complete mirror of Disk 0 so that if Disk 0 dies, Disk 1 is ready to run?

I have a 500 GB hard drive and a 250 GB hard drive. I want some kind of redundancy to be setup with them. I have both drives up and recognized through disk management. I don't have a RAID controller card or anything of the sort to do it hardware wise. Is there something that I can do inside of windows server 2003 to make them mirrored or something to the effect that if one goes down I can rebuild it. I also know that it can only be as large as the smalled HD. So it's going to be limited to 250 GB. And the last part is if I partition part of the 500 GB hard drive off can I still use the other half.

I have 2xWD black label 500GB in mirror raid. Obviously they are set as primary now.
I want to make the SSD primary, the raid secondary drive and do clean windows 7 install on the SSD.

Before opening the box I would like to make sure about few things.

1. How do you set a mirror raid as a secondary? Do you need to move any jumpers or just set it from the bios?

2. Since I don't have CD on this computer I have to either make a bootable flash drive OR if there is an option to install windows on the SSD from the current setup (while with my existing windows install and the raid as primary) and then switch the SSD as primary and boot from there? Any caveats here?

Anything else i should know before doing the move?

Thank you!

A:Going from HDD mirror raid to SSD, what I should know?

If you want to be sure, remove the RAID drives, or just pull the power from them. Install the SSD and do your clean install. Once complete, shut off the computer, reconnect power to those drives, and boot up again. You should be able to verify in your BIOS that the SSD is the first drive the system looks to when booting.

I have had to reformat my hard drive because I thought it was the best way to get out of a mess I got myself into. You know the computer from HELL day.
I have a RAID 1 (Mirror) configuration and really want to keep it. This system worked for over 3 weeks flawlessly and all of a sudden I think I had some software issues or graphic card issues. I then did a memory check and the disk corrupted my system.
So I am at ground 0 and I can't even load XP Pro into my system.
For some reason it thinks there is something on my drive and it is in a loop of booting, then it formats my drive, then it thinks there is a windows folder on it still and askes me to write over it. I say ok to let it write over it and I never see any graphics it just reboots and repeats the whole process over and over again. I am loading the software correctly I see the license agreement but it never starts to load just goes in and copies the 3rd party software like it should then it writes some files on disk but in a dos type enviornment. I never see the black XP screen in this whole process.
Do you think it is seeing the mirrored drive? Any ideas?

11 hours between last night and today... I need a drink!

Thanks for any help you may have.

Did you use the 6 XP pro boot floppy disk , to do a clean install ? just curious
also when you mirrored the OS did you do that on a seperate hard drive or same hard drive ?

This is what I would try when you're at this point installing XP - do a totally clean install
( If an existing Windows XP installation is detected, you will be prompted to repair it. At this point hit the ESC key (do not repair).
- The screen will now list all existing partitions and un-partitioned space for each hard disk. Use the cursor/arrow keys to choose where to create the new partition. Press D to delete an existing partition or press C to create a new partition in un-partitioned space. If you press D to delete an existing partition, ) make sure you delete the partition - then install on you're newly partition drive

I am not a hardware person at all. I have a pretty good hardware problem. Can someone please explain the best and most practical way of handling this situation. I want to do either a RAID or a mirror array. But it needs to be software managed, it's not going to be a hardware set up. I have two hard drives but they are not the same size. Is there a way to set this up virtually? If anyone has any input at all feel free to post. This is under a time constraint so the faster the better! Thanks!!!!!


Yes, you can use different hard drives no problem. The size of the smallest one will define the size of the array. As for how to set it up.. Just google for your specific OS. Like "windows raid".

I searched but I can't find the same issue. I know how to reconnect a drive in a Mirror raid when the previous has failed, then the system will copy all files and rebuild the Mirror.
But my problem is the following:

- I had on Mirror raid consisting of 2 identical drives, for data security.
- Yesterday, I put a new drive in the system (not for the Raid array, just a regular one for other purposes)
- I had to rearrange all the drives inside the pc and redo all the wiring and plugging.
- When I started Windows, it said one of my two raid drives was missing and that the redudancy failed. I thought the drive was dead but it wasn't.

- I actually right clicked on it in disk management and did a "reactivate volume", then the drive went back online and worked, it doesn't seem to be damaged at all and is marked at "healthy". I did a quick scandisk and everything is fine.

- Now my raid Mirror is broken, I have the 2 drives but they aren't connected together.
- They are still marked as "dynamic" while being separated.
- When I right-right on one of them I don't have any option to reconnect them into a Mirror. Extend volume" and "add a Mirror" are greyed out.

I seem to be stuck. Any idea of what should I do?

Thank you for helping.

A:How to re-mirror a drive to RAID

We see nothing but problems here with RAID ever since Win7 beta. Not a single good report of RAID, almost daily reports of disasters. It isn't even redundant - the very first letter of it's name! - since users often lose everything when a drive fails or crashes.

You are best off to unRAID your drives and install Win7 to the fastest drive, or to an SSD which is the best upgrade you can possibly have - even better than buying a new PC without one. Then after install add back and format the other drive(s) for storage, data and the all important and reliable backup images taken just after install and setup and then regularly.

Then focus on doing a perfect Clean Reinstall Windows 7.

I wish I had better news for you, but it is not something I mess with because it only gets worse, never better, compared to the perfect installs we have helped millions get here.

System is a Dell Dimension 8400 with 2 identical SATA HDD's using Windows XP Pro SP2. How can I repair this raid to access the data that is on the drive(s). My only thought is to get the raid drivers to the PC and have them on a bootable floppy or USB device and press F6 when booting from the Windows XP Pro CD. Correct me if I am wrong in this process. I ran the disk utility on the system to try and identify the BSD, but nothing shows up. The BSD stop error points to the NTFS file system. Yes, I have a copy of an ERD Commander disk to access the drive, but I did not boot with any F6scsi (SATA) drivers for the raid. It did not see the C:\windows directory so I am assuming the reason is the drivers mentioned above.

Help on this would be greatly appreciated.

The pre-install driver will allow setup to install the files correcty on the RAID array this is offered for XP only.

When you have created the RAID array in the BIOS Utility and you launch the windows 7 setup does it show the new array as a possible install location? If so there is no need for a pre-install driver (Win7 supports a variety of RAID setup out of the box).

If you do need a pre-install driver, you have not been offered one for Win7/Vista on the Manufacturers website. The only solution to this I have found is to Download "7lite/Nlite" and build the "post install" driver into the win7 image then burn a new disk (or burn to USB pen for faster install).

A:Question about Mirror HD RAID setup

Mirror raid would definitley be useful. Bear in mind that it only helps against drive failure, not against viruses etc. I assume you woul dalso back up to an external on a daily/weekly basis, in case ofcatastrophic failure.

as far as setting RAID up goes, not sure exactly on your specs, but you should br able to get a raid card- think they run around 20-40 dollars, but not sure. Certainly not too much. It plugs into an expansion port and allows you to plug drives into it, exactly as if it was going to the mobo. The card then allows raid, although it will need rivers- al supplied and not a problem.

If you go that way, and dont feel confident, probably worth considering getting someone to do it for you. That way at least you know it will be done correctly and give you what you need.

Checled your spec, and seems you have free pci slots. Suggest that one of these

Would probably be suitable, but check first.

Hope its useful

I have 3 RAID mirrors, 2 X 2Tb and 1 X 1.5Tb.

The small mirror (1 X 1.5Tb) degraded so rather than replace the dead 1.5Tb (after securing the data) I deleted the volume and bought 2 X 4TB drives.

Replaced the 1.5Tb discs with the 4Tb discs and double clicked on the Intel Rapid Storage Technology icon and loaded the program which saw the new discs as 3,815Gb drives

I then created a new RAID mirror, no problems. BUT, the display shows the 3,815Gb discs but the mirror size is only 1,718Gb.

Could someone, more conversant with the topic, please confirm that RAID mirrors are limited to 2Tb? As it appears that my new mirror has lost a factor of 2Tb.

I contacted Gigabyte (the manufacturers of my P55A-UD7 motherboard) and they suggested that I SHOULD be able to build 3Tb mirrors. It seemed strange to me that they couldn't say if the MB could or couldn't handle larger that 2Tb mirrors, after all they are the manufacturers

Maybe someone more aware of Intel limitations can answer my query?

My MB (and whole system) is a couple of years old and I am running Windows 7 64bit with 8Gb ram.

Thanks in anticipation

PS I got a message that the drivers for the 4Tb discs failed to load!?

Motherboard: Asus P7P55D-E Pro
Windows 7 64bit
4 Hard Drives, 1 is boot drive (C), 1 is non-RAID and 2 set up as RAID 1

I am about to replace my Boot drive with a Crucial M550 SSD, by cloning the current drive to the SSD. This appeared a fairly straight forward procedure until reading of the problems associated with running in AHCI mode. I've seen the tutorial and the need to modify the registry to allow installation of AHCI drivers.

Because I have RAID 1, the Intel P55 chipset SATA is set to RAID in the BIOS. I'm presuming that if I were to change to AHCI the RAID would be lost and the PC would likely not boot at all.

If possible could you tell me the best procedure to follow to set up my SSD with my current set up. I'd prefer to avoid fresh re-install and clone if possible.

Thanks for any help.

A:AHCI and Installing SSD on Mirror RAID 1 Set Up

If you have RAID set up with the same controller that the SSD will use, the RAID drivers have the same functions as the AHCI drivers. You do not need to change to ACHI.

Cloning or using an image of the operating system to the SSD should work just fine.

Iwill KK266 motherboard with 1.4 ghz Athlon, 256 PC133 ram.
Promise Fasttrak66 raid controller
Two IBM 8.4 gb ata33 drives, each a master on its own channel.

I fired it up, and made a raid 0 array with the two drives, 16 gb total, 64 kb stripe.

Ran the Windows XP Pro install CD, and created two partitions on the array of about 8 gb each, and installed WinXp on the first one, formatting it with NTFS. It took a LONG time to format (well over an hour)

Once the Windows desktop was running, I installed a few more programs. The ATTO disk benchmark showed transfer speeds in the 17000 range for the C: drive, so I thought all was well.

But then I noticed I only had less than 700 mb free on the drive! I checked the size of what was installed, and found it to be just over 1300 mb, giving a total of just under 2 gb. These figures are shown on the drive properties screen.

Next I fired up the Disk Manager in the Administrative tools, and it showed both partitions in their correct size of 8 gb. No clue why I was only apparently accessing 2 gb of the C drive.

I then tried formatting the D drive, but after another long process, the format failed. No reason given.

What's going on?? I seem to recall there was some sort of 2 gb partition limit in FAT, but I'm using NTFS.

my question is this: WHICH IS BEST RAID ARRAY TO USE?

the reason we decided to use these method is for extra performance - now im aware that RAID '0' stripes the data so if 1 drive were to fail then he would have to re-place it or re-install windows on single drive - but you get the most free space and best performance from this...

what about MIRRORING? as he doesnt use much space anyway would he be best with this option? DO YOU STILL GET THE SAME PERFORMANCE FROM MIRRIRON AS YOU DO WITH STRIPING? (except you get less space but if one drive fails everything will still run off other drive....)

his disk usage would only be about 40Gb (without mirroring)

if you DO get the same performance with mirroring then how much space would he get from 2 x 160Gb...? (and installs obviously use double)

would he still get 320Gb with the 40% performance increase from raid'ing two drives together - just installs are double? (thats fine in that case he would only use 80Gb of the 320Gb which leaves him AMPLE)

I noticed it only had a 32 MB CACHE when I went to get another one. I then asked for the version with a 64 MB CACHE (WD1002FAEX), paid for it and left. Will these two hard drives work together in RAID if they have different sized caches? Please give me any info/experience you may have with this or anything with RAID would be helpful, thanks.

A:Help w/ RAID Array

The short answer is yes, they'll work. Onboard cache is internal to the drive, and as long as the drives are the same size, then RAID 1 (mirror) should work fine. I don't think it would make much difference, but the drive with the larger cache should be the primary drive just for efficiency's sake.

When I bought my PC 7 years ago, I asked the techs to create a Raid 0 array with my 2 200GB WD drives. Recently, I have been reading the comments here and on other forums to stay away from Raid arrays as they are more problems then they are worth.

What I want to know is what is the best way, and procedure to accomplish this, to remove this Raid 0 array and use my 2 200GB SATA drives as separate drives with the OS on one and data on the other. I will probably partition the OS one as I do not need 200GB for Windows 7.

Am I correct in assuming that once this RAID 0 array is broken, I will lose everything and will have to do a clean install of Windows 7 plus all my apps?

Backup all of your data, make sure that you have backed up all of your data. Remove the array configuration, get out your Windows DVD, reinstall the OS, patches, and all applications, copy your data back from your backup.

Hello. I am new in installing SATA HDD so i am confused when i installed the drive for the first time the nvidia raid bios setup asked me what type am i going to use on the HDD so i selekted the first one that was working (striping). Now my question is: did i selected the proper type ? because i saw that there is other like mirroring and stripe mirroring. If a made a mistake how can i fix it.

A:Raid array

It depends what you want to do. Without getting into a discussion about the value of RAID on a home system in general stripe is what you want. Do some reading here. RAID0 is stripe and RAID1 is mirror.

Just make sure you do back ups of your data to another storage source.

I am having a problem with setting up a Raid 1 array. I am using Windows Vista Ultimate 32 along with an Asus M2NPV-VM motherboard. After viewing videos on Raid Array setup on Youtube, I decided this chore should not be so difficult. I entered the bios and followed the prompts and made my Raid 1 array. No error messages, and both of my WD3200 HDD were listed, and the array was boot enabled and labeled healthy.
I then inserted my Windows Vista Ultimate CD and clicked on Repair, and on to restore my pc. Windows discovered my external backup, and I then chose the backup that I wanted. I followed the prompts and then clicked restore and received a message that stated that there were to few drives or not enough space to continue. I now do not know how to proceed. Any suggestions would be helpful.
I call this PC my "learning PC". I am trying to learn some of the more exotic functions of my PC. I have read that the Windows Vista built in backup utility is good for backup restore, but not to be used for Raid. Is this true? If so, what product would help me with this issue? Thanks in advance for any suggestions.

Most cards that support RAID1 will allow you to use two hard drives that are not identical. The smaller of the two capacities will be the size of your RAID1.
ie: Drive 1 = 998GB and Drive 2 is 1TB, the RAID1 size will be 998GB

I'm looking into replacing the mirrored drives in my IBM xSeries 235 with larger capacity drives, and was wondering if
anyone could tell me if it is possible to remove and replace the secondary with a larger drive, let the mirror rebuild,
then replace the primary with a larger drive, and once again let it rebuild... then, (and this is the iffy part...) can I boot from an Acronis or Easus disk (or similar partition utility) and just resize the partition to use the entire drive? As is understand it now, if I rebuild the mirror with larger drives, the capacity will still be that of the original (smaller) drives unless and I can somehow resize the partition.

When I go into the BIOS and switch on the RAID and configure it as a mirror, Windows will not boot.  The Windows logo comes up but then I get the blue screen of death with an error code of 0x0000007B.  If I turn the RAID off in the BIOS and reboot, Windows boots normally.  I tried installing both the AMD RAID drivers and RAIDXpert Utility ( and changed the registry settings suggested by Microsoft ( but nothing has worked so far.  Does anyone know why this might still be happening and how to fix it?  Thanks in advance!

<<...want to set up a RAID 1 mirror without reinstalling Windows.>> 
I don't think that can be done.  In order fot the O/S to be mirrored, it seems that the RAID must already be in place, prior to Windows installation.
Just opinion.
You are getting the BSOD because the RAID is not properly set up and the system can no longer boot to the single drive with Windows on it, IMO.

A:RAID 0 array is broken


3 drives in a RAID array ? Maybe 2 of them are.....

If one of the drives in the raid array is a gonner so is all your data....Raid 0 offers no chance of data recovery if one of the drives fails.

Find out wich drive it is and replace the drive and create a new array...That all you can do.

As for 3 drives being in the array I Believe that your Primary drive C: IDE 1 is not in any of the Arrays but the 2 on IDE 3 are. Disconnect the 2 Raid drives And disable RaiD in the Bios and see if she boots then.

Hi all.

I currently have 2 500GB drives configured in a RAID 1 array (totalling 500GB of available storage). This is quickly filling up and I will soon need to add more space. The drives are currently attached to a 2 channel RAID controller PCI card.

What I want to do is buy a 4-channel controller card (like this one) and two 1TB drives to add to my array. Totaling 1.5TB of storage.

Will this work or do all the drives need to be the same size? Will I be able to set this up without having to wipe the existing drives? Is there anything else that I need to be aware of when setting this up?

Hi There,

I recently built a new PC. I used an ASUS P5WD Premium mobo, 2 gig or Ram, ASUS ATi PCi Graphics, 2 Maxtor 300 Gig SAT2 H/d's, and Sony DVD-RW & DVD-Rom.
I setup the MAxtor's in Raid 0 (Stripe). My pc failed to boot a couple of times, but went ok after a re-boot, but a few days ago, it had turned itself off. When I re-booted it, I noticed that although the Raid Array is listed as normal and bootable and both H/d's are seen, one is listed as "Error Occurred" and will not boot. After some fiddling it does get to say that Windows cannot boot due to the ...system32\config\system file being missing or corrupt, but if I go to the Repair consol from my XP CD it will do nothing. If I try "CHKDSK" it says it has unrecoverable errors, and it does not appear to be able to access the h/d's in any way such as making directories, or displaying the directory tree!

I have new drives to go in to get me up and running again whilst sending the faulty ones back, but is there a way of getting them up and running to be able to get some files of of them, and/or wiping them before I send them back. Even better, can I repair? I have tried the Maxtor Power Max software but it does not see the h/d's, I guess because they are in a Raid Array??

Any help please??

Hello all and please be gentle with me as I'm an intermmediate level of expertise. Maybe not even that. I had my Raid 5 crap out on me on Sunday and I get an error message when the RAID controller's BIOS boots up. It's a Highpoint 1640 controller and it has driver/BIOS version 2.06s on it. The controller's BIOS screen comes up and lists hard drives 1&3 and then has a little message screen that asks "power off, destroy, continue". If I select "continue" and press enter then a second BIOS screen comes up (same as the first screen) only this time it has hard drive 2 listed and has the same little message screen. Through experimentation I plugged and unplugged various drives in different combinations and think I've determined that the drives 1&3 are the parity drives and drive 2 is the original hard drive that 1&3 have the split data because if any thing other than 1&3 is plugged/unplugged I get the bootscreen screen that ask insert disk/ boot from disk or press F1. First question: Does this make sense/sound right? Second question:If I select "destroy" on the second screen that lists the 2 drive will it destroy data on all three disks or just on 2?

So, I have an external hardware Raid 5 array consisting of 4x3TB drives yielding little over 8TB of formatted space connected over eSATA. The array has about 5.5TB of data on it. One sad afternoon I was copying some data when my computer decided to freeze. It did not "un-freez" itself in timely manner so I was forced to manually reboot. After the reboot all came back online, but the windows gave me message that if I want to use the disk (RAID array) I will have to format it. Needless to say I turned pale.

The RAID utility shows the raid as intact with no errors. The Windows recognizes the "drive" and does assign it a letter, but I cannot access it (it wants a format). The disk manager recognizes the "drive" as healthy, but in RAW file format. I have used Active Partition Recovery (freeware) on it and it does recognize the "drive", partition and all the files/folders (can't copy and paste them, figures). However, in the properties it states the the GPT is damaged. All the data is there, but I can't get to it or get it out. What are my options at this point?

I'm having a problem with a potentially failing RAID array and/or disk drives.

Two weeks ago, I was burning a DVD from files on the RAID array when the burn failed with a data read error. The array subsequently displayed the following characteristics:

1. Event Viewer showed a 'The device, fasttrack1, did not respond within the timeout period' error, followed by a thousand simultaneous errors that said 'An error was detected on device.. 'harddisk2'.. during a paging operation'.

2. The RAID drive and all directories were viewable in Windows Explorer. No files within those directories could be read or written, however, and switching to thumbnail view would not show thumbs of images of any size.

3. The Disk Manager within Computer Management would not detect the RAID array.

4. After rebooting, the array works as usual. It has again failed during another DVD burning operation just today, and again works after a reboot.

I noticed something odd...

In an attempt to ensure all files (including boot files) were installed on only my SSD, I disabled all my other HDD's in the BIOS.

Installed Win7 RTM x64, everything worked well. BUT when I re-enabled all the other HDD's...Win7 blue screened before it could load (got half way through the animation, then poof, blue screen)

Wouldn't boot in Safe mode, System restore did nothing...

Reinstalled Win7 with my SSD and RAID array enabled and everythings fine.

Seems Win7 can't handle a RAID array being added after installation, as in it can't find or handle the driver for it when it gets suddenly added.

Anyone have a similar issue? Not looking for a resolution because I have everything running fine now. Just curious if anyone has encountered this or similar.

Win 7 does seem to be finiky when it comes to raid. I found out the hard way not to remove the raid when I recommended a user not have the controller attached when he was installing.

I installed the drivers stickyed at the top of these boards before attempting to recreate the array and the controller shows up in device manager. I haven't started restoring the backup yet while I figure out if its seeing the array properly and if not what I can do to get working properly.

I currently have 2 * 1tb hard drives in a RAID0 array.

I have just installed a 120gb Samsung SSD drive and want to reconfigure the array so I have a more traditional setup ie:

C: 120gb (OS)
D: 1tb (Files)
E: 1tb (Video)

I have run boot & nuke to remove all trace of everything on the drives, unplugged the array and plugged the drives into different sata ports on the motherboard, but BIOS still shows the hard drives as 'Performance' 2tb combined.

Any ideas how I can break the array so BIOS lists as separate drives?

A:Breaking A RAID Array

I wouldn't think that was possible. Did you completely disable the RAID functionality in the BIOS? I could see them showing up as inaccessible, until they were formatted.

Was this a software RAID setup, or were you using a controller?

Hey all,

So I'm running an ASUS M4N72-E mobo which has the Nvidia nForce 750a SLI chipset with built-in SATA RAID. I bought a pair of 1TB Samsung SATA hard drives to set up in a RAID 1 (mirrored) array for backing up pictures and the like, but I can't get the thing to show up in Windows for the life of me...

I first installed the nVidia driver set which supports in-Windows setup and configuration of RAID arrays (Nvidia Mediashield). With that all installed, I shutdown installed the two drives on SATA ports 5&6 which are supposedly for dedicated RAID according to the mobo manual. I went into the BIOS and set onboard SATA to RAID, and went to the RAID configuration utility to make sure both drives were showing up (they are). At first, I didn't set up the RAID in the BIOS config because I was going to do it in Mediashield.

Once I got back into windows the two drives show up as unpartitioned drives in Windows drive manager, and so I load up Nvidia Mediashield go through the steps to set up the array, and when I click "finish" the utility locks up for about 5 minutes (at first I thought formatting the array), but then closes with no messages. Once mediashield closes the drives no longer show up in the device manager or drive partitioner, and no RAID array shows up either. Rebooting is the only way to get them back. I've tried plugging the drives into different SATA ports, tried setting the RAID up in the BIOS config utility and then booting to Windows, and trie... Read more

My in-laws have an older Dell desktop PC running XP and recently are getting a message telling them that one of the drivers in the raid array is bad. It looks like there are 2 drives '0' and '1' and the #1 is the bad drive. They are both the stock 250GB WD hard drives that came with the machine. Do I need to replace it with the exact same drive or will any SATA 250GB work? Let me know if more info is needed. Thanks

Check the specs of the failed hd (ie make/model) online to verify *IF* yours is hot pluggable - - you should match the specs

I have a lot of experience building my own computers but no experience at all with RAID arrays. I have purchased a RAID PCI Card that should arrive at the house today. I already own 2 Seagate 80 gig hard drives and want to set them up in a RAID 0 configuration. I have Googled to try to find instructions for setting it up but really haven't found setup instructions. From what I have read, it looks like I will lose everything on my 2 hard drives and will have to reload OS and software again because I don't have a 3rd hard drive. For just a quick start, I plug in the PCI card, install both HD's, electrically connect the 2 HD's to the RAID card, and then reboot? Is there some type of software that needs to be loaded for the RAID on the reboot? You guys know of any place I can find instructions on how to do this? Any assistance would be greatly appreciated. Thanks.

OK....what's the deal?
I have 2 - 200GB drives and 2 - 80GB drives, This totals 560GB.
From this, I'd like to create Array1 with 10Gb's for the C drive and OS.
Then I'd like to create Array2 with 550Gb's for my data files.

I know I can do this if I was using SCSI disks with Compaq's SMART controllers, but I can't find anything that says I can do it with IDE ATA.

SIIG's best only allows raid0, raid1, and raid0+1
Promise is worse: they truncate the larger disks to match the smaller disks.
Adaptec is unclear whether they can or not.


A:Can't you do multi-array raid with IDE ATA hdd?

You haven't stated what OS you're running, so I'll assume you have Windows 2000 or XP (you can do this in Linux too, but I haven't tried it). What you can do is make a RAID-0 of the two 80GBs and a RAID-0 of the two 200GBs (using whatever RAID card you get). Then make a 10GB partition on the 2x80 array, and install Windows on that. Then you can just use Windows' built-in software RAID to join the rest of the 2x80 array with the 2x200 array to make a single large JBOD drive. That way all your data is still striped, but you get the 10GB + 550GB configuration you desire.

I was wondering if anyone here has any experience setting up a RAID 0 array on a Gigabyte P35-DS4 mobo? I read the following about running a RAID 0 array to help enhance my Oblivion game play...

Setting up your system to run on a PAIR of very fast SATA hard drives is the first step towards alleviating this problem of massive disk swapping (and its resulting bottlenecks). Those drives should then be configured as a RAID 0 array. Oblivion and your other games should be run entirely from that array. By having a pair of drives operating in tandem, the data can be swapped back and forth at an enormously faster rate and your gameplay will be incredibly improved overall.

Any help would be appreciated. Thanks

A:Help Setting Up RAID 0 Array

Typically with all standard RAID setups, you have an option before Windows is called to take over the booting where you can set up and make changes to your RAID. This is usually either in the BIOS or right after the POST screen before Windows. It's usually pretty quick and involves an F-key to load the settings menu.

I don't have a RAID but as far as I know, you plug in your drives (in pairs or quads, etc etc) and load this settings menu and tell it what you want to create. It should fire away and build the RAID and life is good. Restart, pop in your Windows disk and off you go.

If you are mirroring your data (RAID 1), if one drive fails you are still alive, not gaining much in performance. If you stripe your disks (RAID 0) and create one fatty disk, if one fails, you're not so lucky, unless you do a RAID 5 (RAID 1s full of 0s, SORT OF like a full house in poker), there's more to lose with RAID 1.

HOWEVER, you will see the best performance from a RAID 0 at the cost of potential data loss without a proper backup.

How does this apply when you are cloning from a parallel install.

I am trying to clone a W2k3 Server Domain controller from a smaller to larger raid array. Both arrays are on the same controller, an Adaptec SA2810. I am booting to a parallel install on a sata drive connected to the controller on the motherboard and performing the clone of the smaller array dead to the larger array.

The system completes the clone then reboots back to the parallel install. I then change the settings in bios to change the boot order and reboot and that resolves the problem of booting to the parallel install, but changing the boot order on the raid controller does not result in the larger array being seen as the C Drive when the smaller original array is connected.

I am loathe to disconnect the smaller original array prior to my knowing everything works, because if something goes wrong and I cannot get the original array back on the controller I could be in serious trouble.

I have gone through the cloning procedure twice already so I know it works, I just have to get past the drive assignment issue. Any help would be greatly appreciated.

Simplest thing to do is to just load W7 and get it over with...but am just smart or stupid enough to consider alternatives...

I have a pretty stable WinXP install but have run into games that require 7 (and DirectX 10).


Can I install W7 on a non-raid HDD (already on my machine) while keeping WinXP on the 250 GB mirror thus avoiding application reload AND potential for issues with the RAID array?

My initial thought is to unplug the mirrored drives and install W7 to the single drive. Replug the mirrored HDDs (same ports). Edit the Boot sequence to allow choice of XP or 7.

How badly would this go?

A:Desire to keep WinXP on Mirror RAID with Win7 on separate HDD

Not well with Win7, which doesn't much like RAID.

A lot depends on the controllers which will need to provide both RAID for XP and SATA/AHCI for Win7.

You can try booting WIn7 to see if it sees the target HD, then try install.

If this fails, unplug the RAID while taking careful note of its settings, try install of Win7 to target HD with nothing else plugged in at all. The SATA controller should be in AHCI mode.

I received a "critical" message of some sort regarding my RAID mirror array. I have 2 of the exact same type and size drives in the array, purchased on the exact same day, about 2 months ago. No problems until today's boot. No modifications to the array since first configured. The computer uses Windows 7. Any ideas how to investigate or resolve this issue? I am currently running chkdsk.

More details:

Drives are WD Green 1TB SATA (32MB cache)

Mobo is AMD

PSU is 550 Watt Logisys

Each drive has it's own set of "hard drive fans" attached to it

The SATA cables have a metal locking mechanism that securely keeps them connected

Update: chkdsk just finished and reported that no errors were found on the File System
