Q: New hard-drive not recognized in bios yet loaded new OS

I have a Dell Optiplex GX270 that I installed a new Seagate Barracuda model

7500.10 part no. 9DJ04E-305 250 Gb hard drive in. The O/S, Windows xp,

installed but the hard drive is not recognized in the BIOS unless I install the

jumper in the master position, when this is done the computer boots to the black

screen that says "NTLDR missing". I have installed the NTLDR file in the folder I

found it in on my laptop but still get the same results. This is the only hard-drive

and I flashed the BIOS. Any help would be appreciated.

AMD Athlon 2200+ with 256MB of DDR Ram.
Biostar M7VIQ motherboard
60GB hard drive

Computer has been starting erratically for awhile. Sometimes it will start., other times it fails and says "HARD DISK NOT FOUND..."

I think the hard drive it finished. With power on I do not feel that 'gyro' effect you normally feel from spinning platters in a good drive.

So I tried a brand new 80GB hard drive. After numerous reboots the BIOS finally recognized it. I was then able to install WinXP. When installation was complete, I did a few Windows updates. Now I'm getting "HARD DISK NOT FOUND..." message again.

Thinking the motherboard battery could be failing, I tried a new one. Made no difference.

I tried new IDE cables. Made no difference.

I set BIOS settings all to default settings. Made no difference. Tried optimized settings. Same thing.

I'm running out of ideas. Anyone have any idea what could be wrong?

PS: Bootup each time is EXTREMELY slow.

I'm an idiot. I removed the jumper from the new drive (not listed in jumper options) and it is seen every time by the BIOS.

Hey all,
I had 3 hard drives connected to my pc with 1 IDE for booting windows and the other and the other 2(SATA and IDE) for storage. I did a reinstall of windows and now my IDE storage drive is not recognized by windows. I looked at the hard drives under computer management but it does not appear at all. It does show up in the bios though. I checked the jumper setting and even tried connecting via usb with an external enclosure. With the enclosure it just found the hardware but no drive on 2 different computers.

Recovering the information on the drive is ideal, but not necessary. That said, does anyone have any idea how to fix this? If I do not find a solution, is there any way to format the hard drive without windows? I thought about installing a different OS on another computer just to format the drive but was not sure if this would work or if there was an easier way.

Thanks in advance.

A:Hard Drive recognized by bios, but not windows

If you are using Vista/XP/Server 2003 or Seven, you can look in Disk Management.

Go to computer management (right-click computer then Manage)

On the left of the window, select Disk Management.

This will show not just the drives, but also the partitions on the drives.

It may be that the drive has become corrupt or is formatted in a way that Windows does not understand. Alternatively, it may just need to be assigned a drive letter.

Hi every body, I am new to this forum. I have fair amount of experience with PCs, including building them. Now I have a new problem. I installed a new HDD, configured it as the Primary 'o' drive (Cable Select). No other drive. The single drive is detected by the BIOS. When I try to install Win XP, the setup loads the necessary files, but when I hit Enter to install OS, I get a message saying "No hard drive is found".

I have tried different hard drives changed the cables, tried it as Master, nothing works, same message. Would appreciate your help.

A:Hard drive is recognized by BIOS, but not byWin XP installatio

Normally this has to do with Windows not having the drivers for the controller. Usually the driver is on a floppy disk or on the CD that came with the motherboard and will need to be put on a floppy disk.
During the install you will be prompted to press F6 to install additional SCSI or RAID drivers. This is where the controller drivers will need to be installed.

Can you list your motherboard specs and we may be able to find you them.

Hello! Having some serious issues, as it seems we all have. So, here's the situation. As a nerd truck driver I bought a laptop for skyping with the family and playing games. Laptop was working fine one night and the next morning I start it up and windows won't boot. Just gives me a blank screen with the infamous blinking cursor in the top left.

After searching the forums, it appears I need the Win7 install discs, which this computer did NOT come with. I may be able to get my hands on a reinstall disc, but I doubt it'll be a samsung laptop disc. I was, however, able to make a recovery disc from my wife's Dell laptop. I thought she had a reinstall disc, but we can't find it.

My current problem, and the most troubling, is that now BIOS doesn't even show the HDD. I checked the connections and they are fine, and I was able to put the SATA drive in my desktop and copied all my important data to my desktop. So I know the drive is good. Nothing is corrupted and all partitions, including the recovery partition is intact. I can't figure out why the laptop isn't showing the drive in BIOS now, though.

I've tried the recovery disc a second time, but it doesn't seem to want to boot correctly now. It worked fine when the HDD was recognized, but now it's getting to the blinking screen, then the cursor jumps to the bottom right and pixelates across the bottom of the screen like it's trying to load.

I can probably get my hands on a reinstall disc if I can download one or ask around tomorro... Read more

A:Hard Drive first not booting Windows, now not recognized in BIOS

Ok, I got the recovery disc to boot again, but still don't have the HDD in BIOS yet. Only option that works in the recovery disc is the command prompt. searching for the HDD that way, but so far, I have only found D: which has the Dirs: Boot, and Sources, and a file called bootmgr. This is along with X: which is obviously the recovery disc. So far, I can't find anything else.

Recently I decided to upgrade my hard disk storage space so I bought a Maxtor DiamondMax Plus 9 160GB SATA hard disk drive. Upon installing the drive I entered the Bios and went into "Intergrated Peripherals" section and set the BIOS to recognize P-ATA + S-ATA drives. When I reboot the new Maxtor drive shows up in Windows Explorer and functions normally. Also in Windows Explorer, my CD/DVD drive appears. However when I put a cd in the drive and click on the drive in Explorer I get the message to "Insert a disc into drive F:". The drive will not read the disc. When I went into Device Manager the CD/DVD drive shows up and says that it is functioning properly. Strange.....
So, I rebooted and reset the BIOS to the setup defaults (ie. P-ATA Drive Only) and when the computer boots up now the CD/DVD drive functions normally but the Maxtor drive is now not recognized. I understandObviously the Maxtor drive is not recognized because the BIOS is set for P-ATA drive only, but why when the BIOS is set for P-ATA + S-ATA is the CD/DVD drive not recognized?

Both hard drives are recognized by Disk Management but when I select Computer on the start menu ONLY the primary 150 Mg drive is recognized.

Had similarities on my pc.

Goto BIOS, there you have 4 options.

Primary Master
Secondary Master

Primary Slave

Set it as follows:

Primary Master -----> Main Boot HDD
Secondary Master -----> EMPTY

Primary Slave -----> CD/DVD RAM
Secondary Slave -----> Secondary backup HDD

I currently have 2 SATA hard disks connected, then 1IDE hard disk on blue IDE slot and 2 IDE cdroms on the other IDE slot. I also have two other external drives each connected to a USB port.

The problem is that the IDE hard disk is not being recognised in BIOS, when I try to switch some settings in the BIOS IDE configuration I have managed to get it recognised but then the cdroms are not recognised, how can I get them all recognised?

Another problem I have is with the external drives. If I switch them on before the computer boots up the POST will hang, so I have to leave them off until the POST ends and switch them on while windows loads so they get recognised by windows with all their sharing settings intact. Is there a way to eliminate this annoying problem?

This may be a stupid question with an easy answer...

But I have a Dell 4600c (it's a compact tower)
So, it only has room for one hard disk, and the stock disk is only 40gb.

I'm thinking of buying a new hard drive.. and I'm currently looking at one on eBay that is 320gb, and it says that it's pre-loaded with Windows Vista.
I currently have Windows XP, and wouldn't mind upgrading... I do have ample RAM (2gb) and a nice 2.8ghz processor. So my machine can take Vista.

But what my question is... Is my machine going to just automatically detect Vista and start running on it? Or am I going to have to go through some painful procedure? Or will this just not work at all?


A:Windows Vista pre-loaded onto hard drive.

Hi. . .

I would be very cautious of this. Can you provide the link to Ebay for this drive? I would be glad to take a look as personally, I have not heard of just a hard drive installed with Vista... not to say it is impossible, but...

Even if legit, your system will need drivers compatible with Vista for all hardware.

Download and run the Microsoft Windows Vista Upgrade Advisor which will tell you if your system is prepared for the introduction of Vista.

Hi all,

I know this is similar to at least one recent thread, but different enough to post.
I am upgrading my sister's machine from a 3.2Gb WD Caviar to a 40Gb Seagate U Series 5 drive, ST348023 from memory, ATA100.
The machine is running a K62 266, not sure of the Mobo, but obviously supports the AMD chip.
From what I have been able to glean from the Seagate site, this drive should be backwards compatible with any IDE connector, but when I stick it in, with the BIOS set to auto-detect all drives, the machine halts trying to detect the Seagate drive, although it will let me Ctrl-Alt-Del and also press Del to get into CMOS setup.
I have tried it as Primary Master, and as Primary Slave, both with the other HD on the same cable, and without it in at all.
Seagate's disk tools are able to detect that it is there, even when not setup in the BIOS. Seagate's disk wizard, which is an excellent tool for installing a new drive, told me that all I had to do was set BIOS settings to auto for that drive, and all would be rosy. It looks at what drive you have, what BIOS you have, and gives you instructions to suit. The documentation tells me that if the BIOS supports LBA and Large disk types, then all should be fine - it does.

Can anyone give me any ideas on what's going on? I have installed quite a number of hard drives in the past, but never come across anything like this.

I have a brand new Foxconn A7GM-S 2.0 motherboad which seems to be unable to recognize my two SATA hard disks. I have ensured that the power connectors and SATA cables are snug, and have tried each pair of the six SATA slots on the motherboard. I also don't hear either hard disk powering up upon boot.

This board is a replacement for my older motherboard, which died rather suddenly. Both hard disks were connected to the old motherboard at the time of its failure, which leads me to wonder if the disks are damaged beyond repair. Do motherboard failures generally affect connected hard disks? Or is my new motherboard defective?

Try the freezer trick. Place your hard drive in zip lock freezer bag to protect it from moisture and freeze it overnight (or a few hours at least). Quickly hook up the frozen hard drive and try to boot from it. If it works, be prepared to copy your important data as soon as possible before the hard drive warms up too much. This is not a permanent fix but it may work long enough to save your data.

Hi, I am recieving the error "BOOTMGR is missing. Press CTRL+ALT+DEL to restart" When trying to boot.

The situation is this:
-I had hard drive issues. Purchased a new hard drive then made a ghost image of my Windows 7 install partition. Ghost image made with Norton Ghost 14.0
-Installed new hard drive, partitioned it with the win 7 install disc. rebooted.
-Loaded ghost image using norton ghost system recovery disc. ghost image was save on an external hdd. i loaded it onto brand new hard drive into a new partition.
-The ghost image loaded successfully, but I now receive the error mentioned.

It obviously appears there is a problem with the master boot record etc. I tried installing windows 7 freshly from the disc and that worked fine, but I need my ghost image from the external to be loaded.

I do not have any OS installed and running currently. I tried installing XP after this happened, thinking I could find a way to modify the boot record from inside XP. However, after installing XP I receive the error: "error loading operating system".

What should I do now; what is the proper way to load this norton ghost 14.0 image of windows 7 onto a brand new hard drive?

Thank you for any help!

A:BOOTMGR is missing - error on boot. Loaded a ghosted OS image to new hard drive

Got a feeling your recovery disc may not have the boot loader inside.

Normally you can rebuild boomgr and this is my suggestion

(1) Load Win7 installation DVD, opt for repair and click Command prompt

(2) Copy from the DVD the program bootmgr.exe and the entire /boot directory into your WIn7 directory if it is the C drive,
if not put it in the C drive.

(3) Put Win7's MBR inside the C drive by command

bootrec /fixmbr
(4) Install Win7 boot sector code in the C drive by command

bootsect /nt60 c:
The bootsect.exe is inside /boot of the DVD
(5) Rebuild the BCD by command

bootrec /rebuildbcd
You should find Xp and Win7 in the next reboot.

The booting sequence starts with something like

The Bios reads the Win7 MBR and loads it into memory
That MBR will load the bootsector code in the first partition recognised by MS Windows and that must be the C drive
It is the boot sector code that finds bootmgr and put it in the memory
boomgr can then show the user the booting alternatives with a BCD menu.

The original recovery disc will never boot in the new hard disk because even if everything is complete the GUID partition reference of the old partition will not never mactch that in the new disk. The GUID reference is unique when a partition is created. You can check it out yourself by command "bcdedit.exe /enum".

I noticed that sometime after I installed windows 7 that my dvd optical drive was not showing up. I have done a lot of research on the matter and have yet to find a working solution. I checked my BIOS and the drive is not listed there, but I'm pretty sure it is properly connected. I have an HP Pavillion dv6000, so the drive just plugs into the slot directed connected to the motherboard, and can be removed by unscrewing a single screw. When the laptop is on I am able to open the drive, and it lights up, so I know it is getting power... I have tried everything under the sun to fix the problem - checking/cleaning the connection port, deleting the upperfilters value from the registry (which many people have said worked for them, however for me it only gave me an warning message in itunes telling me the registry files for burning/importing cd's was missing), reinstalling gear drivers, and running the microsoft fixit programs (they just tell me they can't find the drive or that it isn't there - thanks microsoft...). Nothing has worked, and it's driving me crazy not being able to use my dvd drive. Has anyone had this problem to the same degree as me?/found a solution to it?

A:DVD Optical Drive Not Recognized in Windows or BIOS

Of the BIOS cannot see it, no software fix will help including other drivers. It is probably a connection problem. If the disk works, then the mobo controller is OK because the optical drive uses the same controller in the chipset.

I have a Dell Optiplex GX280 SD. When I first purchased the PC it came with a CD-ROM drive and Windows XP Professional pre-installed. A few months after purchasing the computer I decided to upgrade my CD-ROM to a DVD-RW/CD-RW. I purchased a brand new DVD-RW/CD-RW drive and replaced my CD-ROM with it. Everything worked well, I was able to play CD's, burn movies, etc. A month later I decided to upgrade my Windows XP with Windows Vista Home Premium. I purchased the DVD and installed it with no problems. My DVD-RW drive worked fine, even after installing Windows Vista.

Then, a week or two later I tried playing a CD; I opened my DVD-RW/CD-RW tray, placed the CD inside, then closed it. Usually when I place a CD into my DVD-RW/CD-RW drive and close it a window pops up asking me what I want to do, however, this time it didn't. I went to My Computer and noticed that there was no DVD drive icon under Devices and Removable Storage. I tried restarting my computer in hope that it would reappear but it didn't.

A:DVD drive not being recognized by neither BIOS nor OS (Windows Vista)

Hi lechevarria89,

Is the drive SATA or IDE? You've established that it is getting power to the driver, but not the information. And since it is not showing in BIOS, but was previously. We start looking at the physical information connector. SATA cables quite often fail, plus make sure the cable isn't bent at a 90 degree angle, with SATA the rule of thumb is "Mess is good!"

I've called a couple of local computer shops. The conscensus is that if it spins up but isn't recognized then the controller card on the drive is probably bad. If that is the case I'm being told that there's no hope.

1. Is it true that there's no hope if the controller card is bad?

2. What are the chances of me taking this apart and replacing the controller card from an identical drive?

3. I think I've set all the jumpers correctly for the drive. I can't remember if jumpers will prevent it from being recognized in the bios. I think I've tried all of the options though...


A:Solved: Seagate drive not recognized in bios

yes when the controller card on a hard drive goes dead then its usually comes to a dead end, personally i have never tried to rip it open and try to replace the controller card, something you could try and do if you wanted to try it, but wouldnt get your hopes up. as far as the jumpers go it doesnt matter where you put it on the hard drive it would show up in the system somewhere you would just have some conflicts going on that would let you know that you need to redo your settings on your drives.

I have a Dell Inspiron 1520 laptop. I have an image of the entire hard drive that I created when I first got the computer (using Acronis TrueImage), and I'd like to restore that image, returning the laptop back to that fresh, clean original state. I've done this two or three times before and it worked great each time.

But now there's a problem. Normally I would connect to the laptop a USB storage/backup drive that has the disk image, boot the laptop from a Rescue Media CD created by Acronis, then restore that disk image from the back-up drive onto the laptop's HDD.

When I tried it this time round, the laptop's HDD was not listed in TrueImage at all. I created a new rescue media disk, tried it again, and got the same result.

I then took the HDD out of the laptop, connected it to an adapter kit that let's you power up and plug in the drive via a USB port and external power supply, and tried the same procedure using my desktop to run the operation. Same result. The drive was not detected by Acronis.

The drive does not seem to spin up at all when it is connected.

** Keep in mind the drive still works when installed in the laptop -- it boots into Windows XP etc. **

When I plug the drive into my desktop, the drive does not show up in Disk Management (Start | Right-click My Computer | Manage | Disk Management). It doesn't show up in either of the two right-side windows. (so there's no way I know of to format it or d... Read more

I have the T110, I can create the recovery discs in Windows but when I restart the computer and press F12 it shows no CD/DVD drive in the BIOS.

So I cannot restore from or boot from the external CD/DVD drive.


A:Satellite T110 - USB powered CD/DVD drive not recognized in BIOS


I don?t have the notebook in front of me but check the BIOS if you can find an option called ?USB legacy support?. If yes you have to enable this feature that your notebook can recognize the external drive.

Can you boot from an USB stick? I mean you can also create the recovery files on an USB stick so this would be also an option to restore factory settings.

I own a Toshiba R630 and recently replaced the original disk with a Crucial SSD one, with a big performance improvement. I've been using the old Hitachi drive in an external case through the eSATA port without any problem, but this setup requires both the combo eSata/USB port and a second USB just for power, so I purchased a 9.5 mm caddy to put the disk on the DVD location.

Today I went ahead. Physically all went good (apart from the fact that I had to take off the back cover, more than 25 screws; I took the opportunity to clean the fan) but when I turned the computer on and accessed the BIOS the Hitachi disk is recognized as an optical drive!

You may see an image here:

After that I could enter Windows 7 (64), Disk Management recognizes it as a disk, but can't initialize it. After rebooting the computer I can't enter Windows any more, as it goes directly to recover mode.

Any help would be appreciated! Is there any way to make the BIOS recognize the second drive as an hard disk?


+Message was edited: faulty link has been removed+

A:Satellite R630 - second HDD recognized as optical drive in BIOS

First of all I would recommend you to check the boot device order.
Probably the ODD has been set first boot device and notebook tries to boot from the HDD connected to ODD controller.
If this will not work, remove the old Hitachi HDD, reset the BIOS to default and try to boot once again.

To be honest I?m not quite sure if the BIOS would support such configuration. I mean not all notebooks can be upgraded with an 2nd HDD and in many cases the BIOS would not support the HDD installed in the ODD bay? therefore this configuration may cause some problems.

I used to have a cd rom and a cd burner master/slaved to my motherboard. a while ago that ide slot died, so i master/slaved my hard drive and my burner to the working ide slot.

a few days ago the computer crashed. i dont remember the exacy error but it no longer recognized the hard drive. when i tried to restart it brought me to the strike f1 to reboot/strike f2 for options screen. i assumed this meant that the hard drive was toast, but upon further inspection when trying to change the boot sequence in the BIOS it recognized the floppy drive but the the hard drive nor the cd drive were recognized. this lead me to believe that the second ide slot had now gone bad as well.

my brother has another dell dimension so i opened his up, removed his hard drive and replaced it with the questionable hard drive. i booted it and got Boot Failure : System Halted.

is this enough evidence of a hard drive failure? ive come to terms with it being time for a new computer but im still hoping everything on the hard drive can be recovered.

any opinions/suggestions?

A:Dell Dimension Hard Drive and CD Drive not recognized

Did you check that the Master/Slave jumpers were set correctly?
Moving a HD to another PC normally does NOT work, unless both PCs are identical in hardware. Put your 'old' HD as a slave in your brother's PC, boot up and see if you can access your old drive. Save whatever you can and burn onto CD/DVD.
Then go buy another PC, anything but Dell or eMachines!
Or better, if you have the know-how, build your own from components.

I have a Dell Dimension MCE 8400 that I ordered with a single drive. In retrospect I should have ordered it with 2 drives and without MCE but that is another discussion. I am wanting to install a new OEM WD Cavier SATA 160 with dual boot operating systems on the same drive but partitioned, XP Pro and MCE. I have installed the WD drive as the second drive (in position 1) and made a partition of 40 GB. The drive is seen by the system. I reboot the system and go into setup, disable the Maxtor SATA drive (one delivered with system and in position 0) change the boot order so it boots from CD, save the changes. I boot the system with the Win XP Pro CD, and in the FDD I have WD SATA drivers. The system boots, I hit F6 and it looks as though it is reading the SATA controller drivers. Needless to say the system doesn't recognize that a hard drive is present. Please help!!!!! If anyone has any ideas or suggestions it would be greatly appreciated.

Hi there everyone,

I recently got a blue screen (not my first), but this time my neither of my hard drives are recognized in my BIOS. I run Windows XP off of my master, and use my slave for backup and for my personal data. While I do work on computers rather frequently, most of it is virus problems and stuff like that. I do have a boot cd that I created and neither hard drive shows up using that either. I would assume that this is a motherboard problem, but like I said, my knowledge with troubleshooting this type of problem is virtually non-existent. Any help would be appreciated. I know that I have not given much information in this post, but honestly, I don't know what needs to be known in order to help troubleshoot this. I am happy to provide any more information that is needed. Thanks again!

A:Hard Drive Not Recognized

Quick question.
Did u had a chance to format the hard drive with the "format c: /s " command?
Usualy when u want to start fresh , you first start with the format of the hard drive , then move on to the installation of the OS, in your case the recovery CD.
And since it doesn't seem to be a hardware problem , "I then turned on the computer pressing the F1 key and run a test and the hard drive was OK " indicated that it's very likely that is the problem. Hard drive not been formated.
Also, in case you have a windows 95 boot disk , might want to start the computer with that boot disk and at the a: prompt might want to type this
sys C:
That should correct any problems in the FAT , and might be able to by pass the format process.
Keep in mind thought... when u issue the format c: /s command , you will wipe out all the data on the C: drive ( as in gone from it )

Works perfecty except for not recognizing 2nd hard drive. It shows 2 100 GB drves in Bios But "My Computer" and "Device Manager" only see C and it is listed as 84.2GB, not 100 as it should be (I know it never shows full size but not minus 17GB) I tried "New hardware" but it doesn't seem to list hard disks Just storage controllers
I changed the second hard drive to another, no difference, I have checked the cable connections to hard drives and even swapped with cable from a similar laptop. Both drives show in Bios as 100GB so it must be a Windows problem, I think.

Hard drives, and electronics in general, don't like to be dropped.

There's a chance it can be only the enclosure and not the hard drive inside; you'd have to take apart the enclosure, remove the hard drive, and try connecting the hard drive inside/internally in your PC and see if it works.

I'm not new to computers by any means (Bachelors Degree) but very rusty on troubleshooting hardware issues.

I have Win XP Professional Edition on an AMD motherboard with Athlon Processor and 2GB RAM. Everything seemed fine until recently. I have noticed that out of the blue, my hard drive will disappear and the screen goes to a black screen with white lettering saying something about no hard drive found. I will reboot and go into bios settings and set it to boot from my SATA drive, however sometimes it does not show my hard drive there. I have to completely shut down the pc and wait an hour or so then turn back on and it boots Windows just fine. This is aggravating. I have purchased a new Power Supply (850w), I have replaced the thermal paste on the CPU due to a vibration and extreme heat coming from back of tower (this did reduce the heat issue). It almost seems like the pc is overheating or something and shutting down the hard drive. Is this possible or just me over thinking? I use canned air frequently on all my pc's to keep them dust free and clean.

In either case the download is an ISO CD-image. Create a CD from this with IMGBurn:

Hello. A month ago I was instructed here on Bleeping Computer that my HD is failing. As it was still under warranty, luckily I got the new HD for free. Now I decided to install Windows 8 on it, and I did so using a bootable USB. I partitioned my disk (system reserved
 + 100GB primary drive + 500 GB secondary drive). I went through the steps until it got to personalizing my settings (finalizing and personalizing my settings took a while to finish). Then the laptop restarted, however, as my boot order was set to USB, it went to Windows installation again. I closed that, restarted the laptop and wanted to change boot order, however there was no hard disk listed or available to choose. I only get the DVD as a boot option. What should I do? Thank you.

A:Hard Drive not recognized

Is the HDD is detected in BIOS ?. Some systems do have an option to disable some boot device by adding to an exclusion list. You should check if the HDD is accidentally moved to the "Excluded from boot order" list.
Some system BIOS uses a HDD emulation mode to boot from USB. If that is the case, USB Pen drive may be treated as the first hard disk and hence your HDD may be omitted from the boot list. Remove the USB stick and try to boot.

I'm trying to replace the hard drive in my Compaq Presario R3200 Athlon 64 laptop and do a clean install of XP. My failed hard drive is an 80GB ATA/IDE Hitachi. The new hard drive is 320GB PATA/EIDE Western Digital. I have no idea what I'm doing, so I thought I'd see how far I could get. When I choose to change the boot order, I get a screen that offers, among other thing, to enter setup. If I choose to Enter Setup I get sent to the PhoenixBIOS Setup Utility with the tabs "Main, Security, Advanced, Tools, and Exit" at the top. The only thing that I understand to do that I'm sure won't cause any unintentional damage is in the Tools tab where I have the one option, which is to execute "HDD Self-Test". The result of the test is "No IDE Device".

My harddrive works great apart from the fact it has to be plugged in twice in order to be recognised by my PC/PS3, for example, i turn my PS3/PC on with the device connected via USB and it wont be recognised, i unplug the USB then plug it back in and it is recognised straight away, it seems to only happen when the device has been left turned off for any great length of time, when i turn my PS3/PC off and back on again (within 5 mins) the device is recognised no problems. any idea what could be causing this problem and how i can fix it???

A:Hard drive not being recognized

You could try:

Go to Device Manager:

Click Start, then right click My Computer, select Manage. Go to Device Manager, then under Disk Drives, right click the External Hard Drive and go to Properties, go to the Power Management tab, then uncheck the option to "Allow the computer to turn off this device to save power"

However, the computer may turn back on from standby/sleep if the hard drive requires any power at all..

Hey all! I am having trouble getting a second HDD to be recognized by Windows 8. Here's what I know, I have it plugged into the SATA 2 port, the original HDD is connected to SATA1, and the optical drive is set to SATA 3. There is an unused eSATA port. I don't know what it is for. I started the computer and entered the BIOS. It recognized the 2nd HDD, but when I start the computer and check to see if it is there, it doesn't show it. I looked under disk management, but all I can see it the primary drive and the optical drive. I have a Levono. Any help would be appreciated.

When a drive/parttition can be seen in the Device Manager and Disk Management, but does not show up in My Computer, most of the time it is only the partition table that is either missing or corrupt.

In such a situation my advice will be to try and fix it with the freeware Test Disk.

So I've recently built a new PC and I installed 4 hard drives on it.

1)256GB SSD
2)500GB HDD
3)600GB HDD
4)600GB HDD

My problem is that the 3rd HDD drive is not recognized and its displayed as "Intel Raid 0 Volume" in Device Manager (I didn't change any settings in BIOS for RAID configuration).

When I enter Disk Management I get the message:

And also in partition management its displayed as "Disk 3 Unknown 1192.34GB Not initialized - Unallocated" (the actual HDD size is 600GB)

Two things I noticed:
- In BIOS all the drives are displayed correctly
- I used a SATA to USB adapter and the drive works fine with all the data on it.

I tried running some Chkdsk tests but didn't get anywhere since the drive doesn't event have a letter assigned to begin with.

Anyone knows a possible solution?

Thank you

I just built a system using an SSD as the main drive. Everything is humming along just fine except that a second 1Tb Seagate Hard Drive is not being recognized by the system. I had to use a Molex to Sata converter to connect it because the SATA Drive coming off the power supply only reaches the SSD and Optical.

I'm rather new at this and so................


A:Hard Drive Not Recognized

Is it detected in the BIOS? Is it detected in Device Manager as a drive? If yes then you likely just need to initialize, partition, format, and assign it a drive letter through Disk Management:

Also, your power supply should have more than one SATA power cable. What power supply do you have?
I'd use the adapter on the optical drive and give the hard drive the SATA connector from the PSU instead.

I have installed a Hitachi 80GB SATA hard drive, and it is recognized by the BIOS and motherboard, but when I try to install WinXP Pro it tells me I have no hard drive installed and therefore can't format/partition/install windows.
Because it's a SATA drive, it has no jumpers and is set to master by default, so that's not the problem. It's a completely new drive, so it shouldn't have anything on it at all.

Due to the dearth of USB ports on this old computer (which still works well), I have to disconnect one of these hard drives to upload photos etc. I use the safe hardware disconnect to do this and then plug the 2nd hard drive back in. It worked fine until now. Evidently the 2nd hard drive was not "stopped" the last time I disconnected it and now I cannot get it to be recognized. I have tried all of the WD suggestions but none work. I did get it listed under "my computer once" but when I tried to open it I got the message to stop it (which I did). Shutting down the computer and then powering up the hard drive (it does spin up) and plugging it in does not work. Sorry about the long description but and help will be appreciated.

Well I am back again sooner than I expected. I am running Win XP Home (upgraded Win98). I currently have two hard drives-14gig with the OS on it and a 60gig for everything else. Both are IDE.

I purchased a Maxtor 120gig sata hard drive and my intentions were to eliminate the 14gig as the boot drive by replacing it with the new one. I didn't have an onboard connection so I installed a PCI controller which the device manager says is working properly.

I figured no sweat, just install the new drive, format, partition and copy the boot drive to the new one using MaxBlast3. The problem is I can't get the computer to recognize the new hard drive when it is hooked up so I cannot do squat.

Anyone got any input that might help me?

It doesn't show up in the bios or My Computer.

I have a Dell Dimension XPS T350 computer that does not recognize my hard drive. It's not a hard drive problem because I have tried other hard drives that work in my other computers.

Also, when I type FDISK , a message comes up saying "No FIxed Disks Present". I had the same problem with my Compaq Deskpro 2000. I attempted to take out the cmos battery by prying it out but it was difficult to remove so I left it alone so as not to create more problems. I tried rebooting again and I was able to get to the "C" prompt, although the "D" drive wasn't appearing when I clicked on "MY Computer". I had to reinstall Windows 98SE. But for my Dell computer I took the battery out and put it back in and the hard drive is still not recognized. Any suggestions as to the problem with my hard drive not being recognized?

Is this a new drive? Did the problem start all of a sudden?

Does the BIOS recognize the drive?

Take another look at the jumper. Some require a jumper only when on a cable with another drive, and some require a different position of the jumper if there is another drive on the same IDE cable. Try removing the jumper altogether.

Have an old Pentiium 2 system that still works great. It did have a 10GB and an 8 GB hard drive(s) inside till the 10 went down the chute. Have been using the 8 GB as my master for a few months....but as its only a 5400 speed things are noticably slower than when I used the 10GB which was a 7200 speed.

So bought a 40gb (7200).....was gonna go for 20 GB, but the 40 was only six quid more expensive. Got it home, installed it as the primary......and bios won't acknowledge its existence. When its searching for the primary IDE, the (press f4 to skip) dialogue comes up, and then nothing happens. Its doesnt seem to detect it, and doesnt even go on to read drive a: (The boot up sequence being a:, c:,e: ). Just sticks there, red light of drive working goes out after a bit then nothing.

Have messed with bios...enabled auto detect and LBA as stipulated on the top of the recognition. Tried old drive (8GB) a treat. Tried new drive (40GB)in my Pentium 4 system....which detects it no problem. So whats up ? I know some older systems have problems with working with big hard drives.....but do they have probs even detecting them ? Is so whats the biggest I can can I find out......heelllllppppppppppp !!!!

Maybe it's your data cable. I mean I had a similar problem before. First I thought it was my hard drive, but after ruling that out, I finally found that I needed a new data cable.

If your system has a spare data cable (like your CD drive, if connected through another cable on your other IDE port) test this one on your hard drive.

You could also test your hard drive on a friend's PC to rule out hard drive malfunction.

Hi from glenaurora

I have recently installed a 2nd 500GB HD and it will not work on my desktop. It's use is for extra capacity only. The OS is Windows XP home. It is installed via the shared ribbon cable with the original 160GB HD. The ribbon cable is plugged into the secondary mother board connector(this is the way it's always been) The 500GB HD(New) is connected to power and the grey 40 pin connector and the 160GB HD(Old) connected to the black 40 pin connector The old HD is set to "master" and the new HD is set to "slave" When both are connected I get a message upon boot up telling me there is no OS installed. When I disconnect the 500GB HD from power and the ribbon cable everything works fine. Could this be a matter of formatting the new HD or does it need to be connected seperately to the primary ribbon cable connector on the mother board? It only lists HD :C and at no time lists the other HD.

It might just be an issue with boot priorities in BIOS. Head into BIOS and check the boot order.

Ideally you want it to be the following:

1st: CD/DVD drive
2nd: Your 160GB hard drive with the OS installed.
3rd: Can be anything really.

Well, my Windows 7 laptop has been dead for a while, but now I want to see if it can be fixed.
The laptop no longer recognizes the hard drive. I checked in the BIOS settings, and it shows there being no hard drive whatsoever. I opened the laptop up and made sure nothing was broken; nothing was. I pulled the hard drive out, and neither the hard drive or the connectors are showing any external damage.

My theory is that it's suffered some sort of internal damage. It was already giving me bad sector warnings and BSODs before the incident happened.

Another theory popped into my head. The motherboard might be going out, as one of the RAM chips that came default with it started causing it to freeze, but removing it would allow the computer to run properly. But one thing that goes against this idea is that I can still run Linux distros off of my USB drive.

Do you think either of these are the cause? Or do you all have any other ideas that might explain it and/or make it run off the hard drive again?

Oh yea. Specs:

I was posting in another thread and realized I shouldn't hijack his/her thread. I also tried looking around the forums for a resolution to my problem and either 1) can't find it or 2) probably didn't look hard enough.

Before I get into the problem, here's my HD configuration:

1 x 500GB SATA HD (2 partitions) -- Master Drive -- Windows 7 Pro 64-bit installed in one of the partitions (150GB partition)
1 x 250GB IDE HD (no partitions) -- Slave Drive -- just for file dump.

Here's my problem:

I installed Windows 7 Pro 64-bit on one of the partitions of the SATA HD. It works great and recognizes both partitions of this drive. However, I cannot "see" my IDE HD. I went through to disk management and I can see the drive there with no drive letter. I tried to assign it a drive letter via right clicking, but all options were grayed out (meaning, not clickable). I read other posts but they either have the same solution (assigning drive letter) or the problem is slightly different from mine. I've had this HD configuration before and had Windows XP Pro 64-bit on it too.

Anyways, I'm not sure what to do and I don't want to delete the files on that HD. Anyone have a solution to this problem? Thanks!

I should also add that the two partitions have drive letters of C: and D: (Windows installed on C: ). Also, I'm not dual-booting (as I see that question being asked in other threads).

My external hard drive (EHD) is not being recognized by several computers that run on Windows XP and XP Professional. The EHD is Western Digital Series 1 USB 2.0 (Old USB 2.0) – Model Number WD1200B05-RNN. It is just over 2 years old and is out of warranty.

I’ve done some reading online forums such as this where users have had similar problems, but I didn’t see any solutions – or, any that I understood, so I ask that if people have suggestions, to guide me through it step-by-step.

It was working a few days ago. The other day, I was doing a file search on it and it stopped responding in mid-search, so I started the search again, and it stopped responding again in mid-search. After that, the computer won’t even recognize it as a separate drive, although the bottom right of screen shows a symbol that there is an external HD plugged in. Windows XP detects that I plugged in the external hard drive and the icon “Safely remove device” appears too in the tool bar. However, I cannot see the drive in “My Computer.” I’ve tried to plug it into 2 other PCs including my laptop, and the same thing happens: it isn’t seen under “My Computer” but the icon appears on the taskbar. I’ve tried to unplug it & re-plug & restart the computer, but nothing. I’ve tried installing the driver again and restarting, to no avail.

Well it certainly sounds like the drive has died.

If it helps, CompUSA is selling a Hitachi 200Gb HDD for $70 after mail-in rebates this week. Better hurry. It ends tomorrow I think.

Now as far as trying to recover data..There is one technique (which sounds really weird but works for some people). Kind of a last resort technique when all else fails and you don't want to spend big money on data recovery.

Put the old HDD in a ziplock bag and stick it in the freezer for a few hours. The cold sometimes helps the HDD work for a little bit of time. You would then take the chilled HDD to a working PC and install it as a slave so you can hopefully copy as much data as possible off it.

Good luck.

I had this problem where intermittently, usually when i came out of sleep mode, the hard drive with my data would "disappear". I would have to reboot to get it back. Whenever this happened I'd get error msgs saying "windows delayed write failed, could not write to the file D:\$Mft". Well, the problem began to get more frequent and one day, I could no longer get the drive back after rebooting. It is a Seagate Barracuda 7200.9 160gb SATA. I ran the seagate tests, it passed.

So I sent the drive back on an RMA and got a new one. THe original one worked fine for 2 years. For about 2 weeks the new one worked fine but NOW its back!!!!

This time, it happened twice tonight as I was working. All of a sudden I get the delayed write error, and sure enough when i check "my computer" it is GONE. I have to reboot. I was working on editing some digital photos converting raw images, each one is about 46mb, and as the program was writing the converted file it took a LONG time to write...and then i got the error.
