Windows Recovery disk shows operating system: Unknown on (Unknown)

Q: Windows Recovery disk shows operating system: Unknown on (Unknown)

I've been trolling the forums here for a while. Lots of great info but now I actually have an issue where I need some assistance.

When I was booting one day last week I got a nasty BSOD when Windows was trying to load. Then on the next reboot Windows 7 said it couldn't load and needed to do the recovery OS option from the Windows 7 repair on the CD. Well, before trying that I did a cold reboot and it got back into the OS fine so I didn't think much of it. Now, I noticed Ghost shows the C: drive status as "Unavailable" and it can't back it up anymore. It does give me an option to restore from one of my old backups. I'm thinking the MBR got hosed up somehow or something like that. But I'm skeptical to run an MBR repair since I have that 100MB partition on my SSD where my OS resides.

Ghost Shot>

This was about a week ago my Windows 7 started acting up right before the big patch Tuesday. I've been running it for over a year now and it's been solid. When I first set it up I installed it on my SSD (Intel 510 120GB) drive. One of the qualms I had with the install is Windows created a separate boot sector on the disk drive where it stored my boot files. This is known the the "system reserved" operating system files 100MB partition. Apparently the way to avoid this is to use a third party partition tool before doing the windows install. That way it will keep the Boot sector files on the same partition which is how I would of liked it for doing restores from Ghost 15,etc. Anyway, ghost was backing up my system C: drive before last week. I have yet to even try and use Ghost to see if it would successfully restore my OS but I've been using it to backup my C: drive anyways. Prior to last week it could backup my C: drive fine. I might try a Ghost restore point from a few weeks back before this happened but not sure yet.

Here's my partition setup in disk mgt.
And here's what the diskpart tool shows:

DISKPART> list volume

Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 H GSP1RMCPRXF UDF DVD-ROM 3167 MB Healthy
Volume 1 D GAMES NTFS Partition 459 GB Healthy

Volume 3 F BIOSLOADS FAT32 Partition 24 GB Healthy
Volume 4 G BACKUPS NTFS Partition 117 GB Healthy
Volume 5 System Rese NTFS Partition 100 MB Healthy System
Volume 6 C NTFS Partition 111 GB Healthy Boot
When I just tried the recovery options from the Windows 7 CD it says "operating system: Unknown on (Unknown) Local Disk." I guess I would need to load my SSD drivers to get this function to work correctly but not sure yet. I was reading the thread about restoring the MBR using the bootsect tool on the CD but I couldn't get the Recovery CD to see my OS. So, do you think I can just put the CD in the drive while Windows 7 is running and run this command > bootsect /nt60 SYS /mbr

I found this info in this thread>
MBR - Restore Windows 7 Master Boot Record

Another strange thing I noticed was in my BIOS my Intel SSD now seems to show 3 volumes and I'm almost certain that was not this way before. It shows these >
A031 intel SSDSC2MH120A2
Intel Volume1
Intel Volume0

Not sure why? I'm pretty tired but I'd like to get my Ghost backing up again and Windows repair capable of seeing the OS. Any ideas what I should try? I'm tempted to do the MBR repair inside widows since it seems MBR related. I only have Windows 7 on this system and don't want to hose it up since it still works fine.

I don't recall loading anything that would of caused this issue and I'm not sure how it came about. I also just did a malware bytes scan and it came up clean. Thanks for any ideas/suggestions!

Note, I just went into my Disk 3 where my SSD resides in DISKPART and did some commands if this helps. It shows both the 100MB and 111GB Partitions on the Intel SSD as "Active".

I'm not sure if this forum supports Windows installed on a MacBook,
but I'd appreciate any help provided.

Regarding my laptop, it's a MacBook Pro bought around 2011,
witn Windows 7 x64 installed from my friend's disc.
(Sorry I cannot remember exactly what it was)
"Barely alive" condition.
Works fine, but suddenly shuts down at times, alert shows battery not inserted (UNDETACHABLE on this MacBook model), won't run without power adapter connected, immediately shuts down when inserting USB cable into 1 of the 2 USB ports, won't detect internet connection, and so on and so on......

That aside, it worked fine until last week.

I was running Windows Update when I accidentally insert USB cable into the wrong port and "forced shut down" the laptop.

When rebooted, I get a flash of BSOD and auto-restart, which leads to startup repair.

From there, I ran startup repair a few times, each time I get the successful result yet Windows still won't start.

Then I switched to Mac OS to use it for some urgent stuff.
While in Mac OS I did went around and did "repair disk" and stuff to the bootcamp.

Next I tried searching for solutions through my phone and did this and that on command prompt.
chkdsk bootrec etc etc tried all posted solutions to something similar to my case.

The next thing I realized was that I now cannot even choose "Windows" on boot and I got stuck.

I'm running Vista Ultimate 64 on a 500 Gig hard drive with 3 partitions.The problem is I marked one of the partitions,not Drive C, as "active" by mistake.I done a Command Prompt to make it "inactive", but when I started the system up again it wouldn't boot.I used the Vista disk for the recovery process, but I got a message "Operating system unknown on (unknown) local disk" i tried fixing the problem with a command prompt "bootrec/fix boot" ,but nothing happened.When I look at the info in Command Prompt it doesn't show the disk partitions, just Disk 0.Also I can't repair because no Disks are listed to be repaired. If I look at the drive in "My Computer" it is full with a file system marked as "Raw" and it wants me to format the drive.I used "Recover My Files" software and it shows some of the documents that are on the drive, but doesn't show any recovery.I looked at some internet post about the message I got and partition and boot problems like I have, but at this point I don't to try any else to make it worse.I would do a reinstall ,but on one of the drives I have some stuff that wasn't backed up.I never thought about backing it up because it wasn't on the C drive.Any help to solve this problem would be appreciated. ..........Kumpie

I had a Seagate drive fail suddenly last week -- a lot like the situation you described, and neither the Seagate nor the WD drive diagnostics even see the drive when it's in an external drive caddy. When I connect it to an internal drive cable, I get a SMART error and the PC hangs on the boot.

Have also tried Minitool Partition Wizard and some other data recovery apps, which CAN see the external drive, but they can't find or recover any partitions.

Suggest you check with Minitool as they offer a free trial of a data recovery app that might work for you.

This is the first time in years that I've had a drive fail and NONE of the data recovery apps have been able to find anything on the drive.

I've resorted to sending it off to a local data recovery service and am awaiting a quote.

I have an Asus G74S. It was working fine yesterday except for being connected to our usual home wifi yet not getting internet. Our other computer, a Mac, accessed it just fine as usual. When I tried to restart my Asus, it only gave me the option to restart Windows normally, which loops me back to the same menu, or enter System Recovery. I tried the system recovery scan 3 times (it took hours each time), restarted between each, and it just keeps bringing me back to the same menu. Perhaps it's because the screen says that it's an unknown operating system.
I can't use a System Restore because the computer says it can't find the operating system and that I need to restart and choose one, though when I restart, it brings me to the same menu and I don't see a way to choose an operating system.

So the other day I got a pain in the butt virus (GFW I think it was) . Well I ran Malware-Bytes and got the infected files off. And I started up the computer again and it looked very weird. So I went looking to see if all my files were there and they were all hidden. Fixed that but it still looks weird. So I did a repair install of Windows and it still looks the same. My next step is a complete reinstall of Windows (waiting on an external I just ordered). I was wondering if I need to go that far or if there is a setting somewhere that is doing this.

Any help is appreciated, Thanks.

Hoping somebody can help me with this one...

I dropped my laptop while it was starting up. Needless to say, it didn't like it.

On restarting, it didn't boot properly, but went to "repairing startup errors", and hung at that point.
I dug out the retail W7 disk I used for installation (Pro x64 with SP1), and eventually got the system recovery options interface working*.
It sees the right partition, with Win7 installed, but instead of a volume label (C:, D: etc), it has (unknown), with a partition size of 0MB. I'm guessing this is why it won't boot into Windows. Sooo... how does one go about fixing this?!
Fwiw, it's a Lenovo Y410p with a single HDD, a mSATA SSD for caching, plus DVD drive.

Recently after installing Teamspeak and not actually getting all addons necessary to join people in an ARMA3 game, I noticed I was having slowdowns.
I did a windows recovery to before the install and it seemed to fix the slowdowns but I'm a little paranoid about both the teamspeak download and the ARMA3 addon downloads---Given that I have a few conhost.exe at startup and several svchost. I'm not sure when they started being there. They are not there in safe mode when I scanned.

A:Bootmgr is Missing - Cant load Recovery Disk as Operating System not found

Hi, we do seem to be getting a lot of boot issues lately, this is a summary of what to do, produced by a Tech after a MS boot camp.
I have put code marks around your best option (that is after startup repair failed to resolve the issue):-

You can use the Bootrec.exe tool in the Windows Recovery Environment (Windows RE) to troubleshoot and repair the following items in Windows Vista or Windows 7:
? A master boot record (MBR)
? A boot sector
? A Boot Configuration Data (BCD) store
Note When you are troubleshooting startup issues by using the Windows RE, you should first try the Startup Repair option in the System Recovery Options dialog box. If the Startup Repair option does not resolve the issue, or if you must troubleshoot more steps manually, use the Bootrec.exe tool.
Back to the top
To run the Bootrec.exe tool, you must start Windows RE. To do this, follow these steps:
1. Put the Windows Vista or Windows 7 installation disc in the disc drive, and then start the computer.
2. Press a key when you are prompted.
3. Select a language, a time, a currency, a keyboard or an input method, and then clickNext.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.

For a while my computer has refused to start Windows. It would get to the screen with the Windows logo and then no further.

I have not replaced any of the hardware since I bought it, and as far as I am aware this problem came on the back of nothing. (It didn't follow any installation of software or hardware.)

Since there is nothing of too much importance on it I decided to reinstall Windows, but after the setup had started it reached the screen from which I was to choose which drive to install Windows to and each was listed as "Unknown Disk." Pressing any button resulted in a blue screen.

If I even attempt to load without using the disk I just get a black screen prompting me to enter the setup disk.

I am currently at work and so cannot post the precise specifications of my computer, though I will as soon as I get home.

In the meantime I gather that I need to look in BIOS to see if my hard drive is being recognised?

I have Googled this problem but each response was slightly over my head, since I'm not sure what type of harddrive I have (though I will once I get home, I have all the documentation).

Though I do not consider myself too dense when it comes to computers, I am not confident enough to fiddle about in BIOS without instructions.

I would like to thank you in advance for any help that you can provide, it would be very much appreciated.

Okay so this is my problem:

I have been having this problem for a couple of days now. I have a Western Digital Caviar 120GB IDE Drive connected to my computer, and Windows XP doesn't seem to recognize it, all 4 of the hard drives on the Windows XP install says "Unknown Disk - There is no disk in this drive" If I press enter, it gives me the BSOD. If I press D, it gives me the BSOD. If I press any key it gives me the freaking BSOD. So I checked my BIOS and it only recognizes my DVD-RW Drive and my CD Drive. I started getting confused. I didn't know what the problem was. I believe this is how much in depth I can go through with this, I really need some help fixing this.

A:Windows XP Install - Unknown Disk

Ok, what IDE channel do you have the 120 GB HDD plugged into, i.e. Primary Master/Slave or Secondary Master/Slave. Where is the DVD-RW and CD drive plugged into? Is the HDD and the Optical drives on separate cables or on the same IDE cable? How do you have the Jumper pins set? The way it should be setup is your HDD should have the jumper pin set to Master or CS (Cable Select), most new drives come set as CS by default, depending if you have one of the Optical Drives on the same cable. The HDD should be on the end of the IDE cable, any other drives should be sharing the Middle or not at all. The Primary slot/cable should be the one you are using for the HDD. If there is an optical drive on the same cable, it's jumper pin should either be Slave or CS. The Red stripe on the edge of the IDE cable should be pointing towards the Power Plug of the HDD Drive. And the other end should be facing the same direction as all the other IDE cables on the motherboard signifying Pin 1. Make sure the IDE cable is plugged in tight to the drive and to the Motherboard, and that the power plug is plugged in tight. Once you have the jumper pin set correctly, make sure the drive is showing up in the Bios. If it still fails, then if there is a drive sharing the same cable, remove it for the time being.

I have used the tittle from another thread as my issue is very similar, only none of what is posted there worked for me.

So I have a WD 500gb HDD. (Actually I am not 100% sure it is a HDD and not a SDD)
I have plugged it in various PC and laptops. When doing so, you get the usual sound que. It also installs the driver according to the little pop up window.
However after that, the drive is not visible in "My Computer".

When I check the drive in Computer Management>Disk Management, it wants me to initialise the disk. Which, I know I do not want to do (thanks to one of your earlier posts) as this will over write my data.
In Disk Management the disk is "Unknown" and "Not Initialised" It also does not give any volume. Pics of both of these attached.

I have tried using Partition Wisord free. It does not even see the drive.
I have tried using Photorec. It does not see the drive.
I have used R-Studio. It does see the disk, but I am not able to scan it. Again also no disk volume. Again Picture attached.

I am hopeful for a solution, as I feel like the symptoms suggest that I do not have a head misalignment. But I might be wrong on that.

Hoping for someone with some mad skills to help me out here.

Thanks in advance!

A:My NETWORK shows an unknown Item ?

Hi Simonwar,
We don't think there is any other client connected to the router. If the computer is both wired and wireless, that might show two different IP Addresses. Make sure the wireless security on your router is enabled, so that no one can connect to your router wirelessly. could be a static ip address also. Make sure the ip address on your computer should be assigned by the DHCP.

To isolate this issue you can login to and check that out. Please follow the steps given below:

1. Open an Internet Explorer and type in "" in the address bar without any quotation mark and press Enter.
2. Click on Login, by default the password might be blank and click submit.
3. Click on DHCP Client List on the left hand side of the page.
4. You can view the Client name and the Client's MAC Address and the ip address which is connected to your router.

Note : If that is a wireless client, you will have to enable the wireless security on your router. That will automatically get disconnected as soon as you enable the wireless security on your router.

If the problem persists, please get back to us with the following information:
1. Model and version number of the router?
2. Number of the computers connected to the router (Wired and Wireless)?
3. If the IP Address is assigned manually on one of the computers?

Thank you.

I have a dell studio 15 laptop Windows Vista Home Premium installed on it. I got this laptop in November 2008, since then it was working fine just when I returned from Germany o india its not working. initially i thought disk got damaged due to x-ray scanning on airports but I read several threads on internet which says it does not erases/damages hard disks same I have also experienced during my several visits in which same laptop has gone through with this scanning process.

I tried to recover my OS by using OS DVD provided with the laptop. I booted my laptop by setting up the bootable device as DVD in BIOS but it does not help me to recover. I tried to install Windows XP also in C derive so that I can see the data(i.e. my all useful and important) present in D derive but its is not allowing me to install windows XP too on it.

While searching information, I came to know that it seems like its a issue of Windows Vista Home Premium and several people have faced the same . In one solution, it is mentioned that OS DVD provided with laptop may not have files to boot and recover so i downloaded a bootable files and tried with that too but that also does not work for me but it has worked for others as per reviews mentioned.

When I reboot my laptop from OS DVD priovided from the dell, I used to get an following errors:

The driver verifier program, Verifier.exe, shows 4 drivers from "unknown provider".

The Drivers tab of Autoruns.exe does not show these.

Neither PowerShell nor Windows Explorer finds them and yes, I even specifically looked in Windows\system32\drivers.

The quick Malware Bytes scan and the quick MSE scan found nothing.

Here is a snip from the driver listing shown by Verifier (sorted so that the unknowns show up first).

A:Verifier shows drivers from unknown provider

The ones beginning with dump are typical in a crash scenario. The top one is the default sata driver supplied by windows, don't know why it's showing as unknown provider.
It does happen though...
They are usually emergency drivers just for the purpose of writing a dump file.

I have two services that show up under services in the Computer Manager: Nwcdbh02ist and Udfstapteet

They also show up in the Ultimate TroubleShooter. In that program, when I click on "Explore Services Folder" for each of these services, I get a message saying that the folder cannot be found.

The Computer Management provides no information about either service other than they are both set to manual, local service and that there are no dependencies on them in either direction. Both services are stopped - I did not set them that way.

Any ideas of what these are? I've already searched the file database here on BleepingComputer and got nothing. A Google search also brings up nothing. Given the rather Germanic appearance to the name, I think Udfstapteet might be related to SpyBot's TeaTimer which I had installed for a while, but I'm not sure.

A:Computer Management Shows Unknown Services

Well, I have discovered one small bit of information. In looking at my HiJack this Log, I have found that Nwcdbh02ist is connected with the NVIDIA Corporation. In googling that company I find that they deal with Graphic cards and video software including software that decodes DVD's for Windows Media player and Microsoft Media Player.

Since my graphic card doesn't appear to be from NVIDIA, I'm left with the conclusion that is related to my media players. I'll have to see if I can play a DVD, and if I can't I'll have to figure out how to get the rest of the software this service belongs to.

I have a small home network (3 PCs and a laptop). These are all with a single cable connected to my router. The wireless signal, I use just to be able to home with my tablet on the internet and GSM. My modem Eurodoc 3.0 is a wireless modem with router. (An all-in-one device Telenet). When I ask a view of my network , I see a switch wich wasn't there before, Compal Broadband Networks, Inc. CH6541. The MAC address of this is almost exactly the same as the MAC address of my router, only the last digit / symbol is different. I found this odd. When I contact my provider Telenet, they say I do have no switch. I find it very strange that in my statement still spot a switch, which also has almost the same MAC address as my router. Further I see on my list 2 APs (WAP121) while I have no additional access points in the home. I suspect that in my list are the details of my neighbors. Can anyone give me some clarity here?

I have a really big problem .
In the beggining of the year, i had 2 hard drives.
Then i bought a Western Digital 1TB hard-disk a while ago and installed it on Windows 8 64bits.

I put all my data from long time ago in it and used it for about 5 months.

It was all fine 10 hours ago when I decided to install Windows 7 64bits (in place of Windows Eight). I formated one hard disk entirely (didn't mess anything with the others) and successfully installed Windows 7.

After the process was done I started Windows 7. The problem is that I noticed that Windows 7 doesn't seem to be able to deal with my WD 1Tb Hard Disk .Windows 7 can see it in Disk Management but doesn't even recognize the Free Space and the Used Space (should be 470gb used).

I can't even assign a letter to it, the only option I have is to Delete it. I tried many others software and they do the same, they partly recognize the 1TB hard drive, but doesn't seem to able to detect free-space and used space. They also seem not to be able to do anything with it but to able to delete it.The only thing they do is point out it's GPT.

A:Windows 7, GPT and Unknown file system

Do you see the drive in my computer? can you run check disk on it? Are you able to boot into safe mode and see if you can access it this way? The drive may have failed. This is why its important to keep things backed up.
I would suggest trying out minitool partition wizard and see if that program can detect it. It may just need to be set as an active drive or be set as logical. I would try that software out, and see what you can do. Another alternative is to boot into a live linux cd and see if you can see your data. If you do not know how to do this, I can give you step by step. I would unplug the drive if your using your computer and not trying to get the data off. If the drive is failing, you do not want it connected to power otherwise the disk will fail quicker. Especially with sensitive date on it, your first task should be trying to get the data off the drive.

I got my 1tB WD external disk and it's not working as it used to. The problem came from nowhere, suddenly, totally unexpected. There is/was my precious data on it which I collected for 10+ years and I'd like not to lose it.

It was working fine a day ago, no problems occured. Hasn't been unplugged since then. Has never fallen. Has never had any kind of error. But: I've seen some kind of ".COM not responding" problem on my PC (don't remember, closed it immediately). I believe my laptop is in a good and healthy condition.

So, what my WD HDD does is:
- it can be seen as a device by my computer. I can plug it out safely.
- diode shows that it's working (not showing the data transfer activity)
- nothing else

What I see in Device Management/Storage is (as in the title):
Screenshot by Lightshot

What programs I used to try to restore partition:
- Mini tool Partition Recovery Home Edition (quick and deep scan, no results. Shows disk as a Bad Disk)
- Mini tool Power Data Recovery (pro, non-free tool, however after scan there was no results)
- Find and Mount (no results)
- TestDisk (quick and deep scan, no results)

What I haven't tried doing is connecting the HDD directly to the laptop.

Any suggestions?

A:External HDD shows as Unknown, Not initialized, Unallocated. Restore?

You should try directly conmcting it. If that does not work, try this: Recover a flash drive turned RAW ? Partition Wizard and TestDisk. Do recovery with partition wizard. (Don't mind the name) But if that does not work, your drive is dead. Like a wise man said, backup, backup, backup!

I recently purchased a used Dell Optiplex 760, operating on Windows 7 Professional. It is a core 2 duo 3 gigaherts 2 gigs of ram and Intel onboard graphics. Could I create a complete operating system disk and drivers on 1 dvd copying the Windows folder in programs files. Looking forward to your input. Thank you. KCBC

A:Creating a Windows 7 Professional Operating System Disk

Yes, it's possible but it's not for wimps! It took me 2 years to create Windows7 32bit and 64bit boot discs of my own. Microsoft has scrubbed most of the legit images from the web, so 97% of them are bogus or don't work. I've got some that I used; can't guarantee they still work. Here's some to try:
Windows 7 Direct Download Links, Official Disk Images from Digital River#
Official Windows 7 SP1 ISO Image Downloads | Windows 7 Forums
Download Official Windows 7 SP1 ISO ( 32bit / 64bit ) from Microsoft

I've had the best luck with these 3; but due to Microsoft's policies don't wait too long to try them as they may be gone by next week or next month!

Once you download a Windows7 Pro ISO file, I recommend you use the free IMGburn program in my signature link below. If you attempt to create the boot disc on flash drive, use WiNToBootIC. This takes more work however.

You'll then have to go to and download the Windows7 Pro drivers for the Optiplex760. Be sure to install the BIOS flash upgrade first, then the Chipset drivers, then audio, then video, then utilities, then apps, and everything else. Reinstallation of the drivers in this order is MANDATORY! Failure to do so will result in a failed Windows installation almost everytime.

Your alternative is to call Dell on the phone and order the Optiplex 760 RECOVERY DISCS; you can purchase directly from Dell for $29-$99. They take about 2-3 weeks to get shipped to you.

I was just about to go to bed when I logged in via remote desktop to to my Media Center PC to schedule a show to record when the Windows update notification popped up. I have it set to install updates automatically on Sundays, but since no shows were scheduled to record for the rest of the night I decided to go ahead and install the updates. After it was done and rebooted I logged in to check and make sure everything was OK.

Now when I run any system program (mmc.exe, task manager, etc.) that usually doesn't require a UAC prompt, I now get a UAC prompt showing publisher unknown. I have the Sysinternals process explorer installed, and when I run it as administrator it shows the publisher correctly as Microsoft Corporation. I checked and there are no errors in the event viewer.

I figured it has something to do with security certificates. I ran sfc /verifyonly and it finds errors, so I ran sfc /scannow and let it repair. After rebooting it didn't fix it though. Running sfc /verifyonly again it still shows errors, and running sfc /scannow this time and I get "Windows Resource Protection found corrupt files but was unable to fix some of them." In the CBS.log file there aren't any lines with "Cannot repair member file" in it, but there are a lot of other things.

Hi, so as I said in the title, my computer with windows 7 gets stuck at "loading operating system..." and eventually after a few minutes says "Boot from CD/DVD:" followed by "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER". When I restart the computer with the Windows disk in it goes to the same black screen and eventually tells me boot from a CD/DVD and "press any key to boot from a CD drive". If I don't press anything it continues to "windows boot manager" and gives me three options between Windows 7, Windows Vista home premium (recovered) and windows 7 home premium (recovered). From this point on wards I can boot up normally (selecting windows 7) and the computer runs fine. If "press any button" then it loads the Windows disk and ask me whether I want to resolve problems or install a new copy etc... I have tried many on the options with no success.
This has been going on for at least a year now. 
I should note this happened at the same time (If i remember correctly) my brother decided to install a third hard drive into the computer, as far as I can remember the only problem afterwards was the inconvenience of needing to insert the Windows disk upon reboot. This was never really to much of a concern for us until we tried to install windows 10, we thought it would magically fix the problem (hopeful I know) but instead the installation crashes after 12 or hours of installing.

It is the proxy server that worries me. Doing a quick search of it there does seem to be a Trojan keylogger that will listen on that port.

A:Disk unknown - not initialized

My laptop took a fall and after that it doesnt enter the boot sequence for windows, stops at the laptop manufacturer logo.

That is bad news mate. Usually a mechanical HDD won't survive physical shock like dropping etc. This is because of the microscopical gap between the head and platter. Heads flying height on modern HDDs is about 5-10 nano-meters. For example: an average human's hair is about 25000 nano-meters in diameter. A drop will most likely cause the head to stuck on platter or cause scratches on platter surface.
I would suggest diagnosing the HDD using "Seagate Seatool" and verifying it's health.

SeaTools for Windows | Seagate
Run the tool and select your external HDD for testing. Then choose "Basic Tests --> Shot Generic" and wait for it to finish.

If the test is a pass, run "Basic Tests --> Long Generic". If either of the test fails, the case will be beyond DIY and you should consult a data recovery pro for recovery.

A:Disk 1 Unknown, Not Initialized

I'm not sure you will have much luck if the disk is not readable. You can usually use a Linux distro to try to read it, but you've tried that. If it can be read you can also try Copy & Paste - in Windows Recovery Console. Other than that you could try Recuva and see if that will work. But, if the disk can't be read, I'm afraid there is nothing you can do if those 3 options don't help.

Now, every time I boot up, I get this error. It doesn't matter how I boot up, (safe mode, last known good config, normal) I get this error. I saw on the web that the fix action was to run the XP install CD and do a repair, so I tried that; BUT...when I run the CD, it says, "unknown disk" where it normally lists my partitions and it won't let me continue past there.

For starters, I'd suggest booting (typically you hold down the Delete key during power up) into your CMOS BIOS and make sure the BIOS sees your drives. Could be somehow the BIOS got corrupted and needs to be re-config'd.

First time posting here, so I apologize if I my post is too vague.

I started up my laptop (Alienware M14x, Windows 7 64 bit - not sure if it's Ultimate, Home Premium, etc...) yesterday and it displayed a message saying that Windows had failed to boot. I restarted and attempted starting it in Safe Mode and from the last good configuration and both failed, leaving me with the same screen with the two options of starting normally or running startup repair. I also tried disabling driver signature enforcement, which also failed to resolve the issue. I then ran startup repair and just let it go for about 8 hours and it just continuously "attempted to repair." I left it overnight and then let it keep going for most of my day today. Altogether, it was running startup repair for around 30 hours.

Hi. I've been working on renaming all my music for the past few weeks using a program called Tag&Rename. I have over 350 Gbs of music so it's been quite the undertaking but I've made a fair bit of progress. Until all of a sudden in the middle of renaming some albums today I was shocked to find that all my albums from A through S were just...not there anymore. All my work had just vanished for no apparent reason. I had just deleted a redundant music folder when this happened and thought that maybe I had somehow deleted more than I asked for but there's no trace of the folders anywhere not even in the recycle bin. I did a complete search of my computer looking for Bob Dylan just to see if I had somehow put all the files in some other folder by mistake but no luck. So I downloaded a bunch of free undelete software packages and scanned my hard drive and they couldn't even find the missing files. It's as if they just vanished. Is there any software out there that can help me in my search, or does anyone know what could have happened? I don't mind paying up to a hundred bucks if I can just get my lost work back. I obviously need a program that will maintain my original folder structure since renaming files and folders and changing my folder structure is all I've been doing.

Do you have a media player plugged in by any chance? (iPod, Zen, Zune).

That would also show up as a removable drive, BUT, if it was a media player, you would be able to access it.
Mine has done that with my camera also. it would show 2 separate that I can't do anything with, and the other which is where the pictures are stored. If I remember, they are called "removable drive" and "fixed drive.

Sorry for a long post, but the problems have been mounting and I want to be clear with what's wrong...

A while ago my computer stopped functioning. I came home to find the screen black, so I hit the hard restart button, and it got to the screen with the Windows logo and a scrolling blue bar underneath, but when that ended and it should have flashed to the login screen, it just went black. I tried hard restarting several times, and each time it would either go black or, in some cases, restart of its own accord. Sometimes it would flash a BSOD, but only once did it stay up long enough for me to write down any of the information. Turns out it was a graphics card issue (I have an ATI Radeon X800 Pro AGP card) - something about ati2dvag.dll being caught in an infinite loop. I researched the problem, and there seemed to be a way to fix it as long as I could log on to Windows somehow, which I could not do. Even trying Safe Mode only got me a little bit farther - I could get past the login screen and the desktop would start to load before it would abruptly crash and restart on its own.

Finally I decided the best thing to do would be to reformat. After using a hard drive cradle to pull off the data I needed to keep onto my laptop, I figured it would be a cinch to reformat and reinstall Windows.

A:[SOLVED] Reinstalling XP - Unknown Disk

Thank you for the detailed post, i wish everybody would give such effort when posting. Now, first thing you should is go back into the bios with both of your hard drives plugged in and check and make sure that your bios is picking up them correctly. It will be show the name of the hard drive and some long number. Then go through the other settings like boot order and make sure that the hard drive is in the list. As for that video card did you update the driver for it recently before the crash, it might of done it automatically. That could of caused the problem. FYI i would of tried Last Known Good Configuration before a reinstall, if it was a bad driver that would of rolled it back to a point before it was installed. Anyways, try those things first and we'll move from there. Good Luck

(1) On most occasions, the HDD in question does not appear under My Computer. Under Devices and Printers, I see the external HDD enclosure as "USB to ATA/ATAPI bridge" (but not the HDD). In Disk Management, I see my internal drives and CD/DVD ROM but for the HDD in question, only "Disk 2, Unknown, Not Initialised" - I get the option to initialise it as MBR or GPT (I cancel at that point).

(2) On rare and seemingly random occasions, my laptop does pick up the HDD as drive F: but usually asks me if I want to format it (nope!). At this point it also appears under Devices and Printers, My Computer and in Disk Management as 'RAW' and 'healthy'.

(3) On three occasions, I have seen the drive name; on two occasions, all of the files - and on one occasion, I was able to copy four files across to my laptop (before losing visibility of it). So I know all the files are there.

However the HDD disconnects itself (or is disconnected) quite quickly, such that I am back to position (1) for the vast majority of the time.

I have tried TestDisk and EaseUS Data Recovery Wizard, which do not see the HDD. I have also tried MiniTool Partition Wizard, which mostly does not see the HDD but on one occa... Read more

Trying to install XP on an old AJP Notebook Model D87P

Setup gets so far as recognising the disk and displaying its size.

"Press Enter to Install Windows on Selected Partition"

Then "Unknown Disk" is displayed and something about a Non XP Compatable Partition

Tried it with 2 HDDs and 2 different XP Install disks

Deleted and Created Partitions

Restored BIOS to defaults

Would it be Software, hardware or Bios

Hello guys! I'm having a problem installing windows XP on one of my computers and it's starting to get annoying. I tried to install windows XP from the CD and i got this error when it asks me too chose the partition or something: 4 unknown disk (there is no disk in this drive) messages. If i press the up arrow i get a blue screen, if i press enter i get blue screen!

Weirdest thing is, i installed ubuntu on it and it worked. It was running windows before, just so you know! ;)

The HD i'm installing it to is the samsung sp1614c. I don't have any drivers for it, in case you're wondering, nor my computer has floppy drive :|

Has anyone experienced this problem? Thanks for you help guys! :)

A:Installation error - unknown disk

Does this happen when you try and select a partition to install to? I am assuming yes.

The drive you have appears to be a SATA drive. As setup loads you should see at the bottom a prompt to press a key if you need to load 3rd party SATA or RAID drivers. You will need to follow that prompt to load the drivers for your SATA hard drive. That should work.

Start with this free tool. You should try to recover the partition before worrying about recovering the data. If you can recover the partition, the files should be OK if they haven't been over-written.

Best Free Partition Manager Freeware and free partition magic for Windows 7, Windows 8, Windows Vista and Windows XP 32 bit & 64 bit. MiniTool Free Partition Manager Software Home Edition.

Select Partition Recovery Wizard. Choose the drive, then full disk, quick scan. Quick Scan may take 5 or more hours.

If the partition is eventually found, select and double click on it. You should then see all files in the Explorer.

I already know about local disk Q (office 2010 beta installs this) but Windows Explorer also shows a local disk M.

Disk Management Utility shows Volume C and an un-named Volume, could this by the mysterious M? When I click it I get "location is not available" error.

How can I remove this or figure out what it is? thanks.

Hi, i'm new on this forum. I was searching for an answer to this issue in a lot of threads but i didn't find something to fix it.

I built an external hd using the hard disk of my old laptop (Fujitsu MHV2120AH PL) and a Woxter i-Case 240.

When i connected it via USB i went to the Disk Manager and saw the unit as "Disk 1 Unknown Not Initialized". But there was something else, the disk has a size of 120GB but the Disk Manager shows only 700MB.

The Disk Manager didn't allowed me to format this partition and when I press on "Initialize disk" it didn't do anything.

I used a Linux Live CD and I had the same issue, i tried to create a new partition table but it didn't create it and GParted didn't allow me to create a new partition answering that i need a partition table first.

I tried with Diskpart without any result too.

This HD had an Windows XP installed on the old laptop and before dissamble it i made a quick format with the Bootable CD of my laptop. The quick format was interrupted when the program was copying the files necesary to install Windows XP.

Do you have any idea?

A:Unknown - Not Initialized Disk (External HD)

Hello Matterito!

You could try a couple of things: changing the enclosure, as this one's controller may be corrupt, or hooking up the disk directly to the computer.
Also, see if your USB drivers need updating.

Following this, it may be that your disk is just damaged. It could be just that the partition table is corrupted, so may be writing full zeros to the disk and repartitioning and reformatting it would help fix the issue. That is in the case that you don't need the information on the drive.

Hi all,

My laptop was slow in booting up/shutting down. Much to my annoyance is inserted the recovery disk and wiped the orignal My documents folder which i cannot access. Recovery software shows the documents still on the drive. My problems seems to be that i've cloned the system, unfortunately i've down this twice and as such have reduced the capacity. Initially i had to decide which system to select at boot up, but resolved that in some way.. I would love to format the drives and try to reinstall but i'm a bit scared. If I delete both bootini selections will my system boot up as it did before this chaos. As i noticed on a previous thread on system in title in blue and the installed one in black

My XP systems was factory installed to my Samsung R50

File system NTFS

Any help would be appreciated

This is an HP laptop delivered by Amazon India on 16 Jul 2014.
HP 15-d005TU
-3rd Generation Intel Core i3-3110M Processor (2.4 GHz)
-500GB Hard Drive Toshiba MQ01ABF050
-DVD Optical drive hp DVDRAM GU90N
-Windows 8.1 64bit

On delivery it had 9 Windows updates installed ( 8, dated Nov 13 and the last one dated 07 Mar 2014, perhaps just before it left the factory). My first priority was to update Windows. A total of 78 updates including the last major Windows 8.1 update 1 akin to a Service Pack - KB2919335 and all this took a lot of time. All updates went on well with no problems.

Now I find that Windows Disk Management lists two OEM recovery partitions D: ( What it was earlier, I did not notice but I presume it was showing one correctly since any abnormality would have caught my attention.)

Diskpart lists all the partitions correctly. And so also bootice.

Now what is causing this and how do I fix it?

I find there is a Intel Manageability Firmware Recovery Agent - My own guess is some Intel driver/firmware may be causing it. As I said it is only a guess. I tried the update with it but so far Intel servers could not be reached though my internet connection is OK. Perhaps someone here may be able to throw more light on the problem and fix.

A:Win8.1 Disk Management shows two OEM Recovery drives

Since the partition does not show up in Disk Management graphical representation, or Diskpart, I would say it was a glitch in Disk Management. If you notice, it does not show a file type on the first listing in the upper window of Disk Management.

What makes me wonder is most systems show the last partition as hidden and a Recovery partition. Since there is no way for me to know how it was originally designated, I cannot say for sure the system is completely normal.

Since you know how to use Diskpart, how about selecting the partition and doing a det par command and then copy and paste the results in your next post. Maybe someone else has an HP system who would know how the partition is supposed to be set up.

I am experiencing the same issue as with jenny123 but with an additional problem. I am troubleshooting a Seagate FreeAgent GoFlex 1TB external hard drive for my buddy. It is previously working but one day, it is not detected anymore by any device. It is found in the Disk Management however, it is listed as Unknown, Not Initialized, and not showing the partition as shown in the screenshot.

When I try to change it from Offline to Online, I am encountering the error:
"Virtual Disk Manager: The system cannot find the file specified"

I also used the DISKPART in cmd but it is not showing Disk 1 as shown below.

The external hard drive is found in disk drives but it is not showing it's model name.

I tried all the recommended software (partition wizard, testdisk, icare) but still no luck. I also tried searching online for an answer but there's no closure to their issues as well. Hope someone can help on this as he need a) the drive and b) recover the files in the external drive. Thanks!

EDIT: The drive can be seen in the Devices and Printers as shown below.

A:Disk unknown, not initialized, and not showing partition


For any serious troubleshooting, diagnostics or recovery attempt, you should always connect an HDD to a direct SATA port. Usually you can easily remove the header of any Seagate Golex drive and then connect it to an internal SATA port.

Let us know what "Disk Management" reports when you connect the drive directly.

I have a Lenovo Thinkpad X-Series running Windows Vista and I've been losing disk space for the past few weeks. I checked the disk with WinDirStat and it says that there's 40.3 GB of unknown disk space and I'm only using about 20 GB or so on everything else. I only have 3.2 GB left...I've tried turning off System Restore/Shadow Storage and clearing the disk space, including deleting old restore points. I've also tried limiting how much the restore points can use to 1 GB. None of it has worked...I don't really have any large programs and I removed all of my games. I've cleared $RECYCLE.BIN and scanned my computer with viruses with Norton and Spybot S&D. No problems turned up. I've also used the vssadmin list shadow storage and that was only using about 2 GB. Can anyone suggest something? Thank you in advance!

A:[SOLVED] 40 GB of missing unknown disk space!

I would recommend going to disk management. I bet the is 40GB of unallocated space. If so you can right click the C: (windows partition) and select "extend" and just click next and it will add the unallocated space to your C: drive.

To get there:

start->right click "Computer" -> select "Manage" -> click on Disk Management in left column.

Please let me know if this works for you.

The computer[nt4.0 server with service pack 6a] was running fine with two physical hardisk both running on ntfs. Later when I installed the the modem i just couldnot install it. The modem was not detected and the system just stoped booting also. I installed a fresh nt 4.0 on the same primary hardisk formating it as fat. Instalation is sucessful. But the operating system cannot access the secondary hardisk which is ntfs. The disk manager shows the disk but says "partition unknow" although it is ntfs. When i open the file manager and try to access the secondary hard drive it says "drive is not readable. disk structure is curupt and unreadable".When I right click on the drive and i hit properties i do not see the sercurity tab. Since I have reinstalled the operating system the service pack right now is service pack 1.
I want to recover data from the secondary hardisk which I can not access please help.

A:ntfs partition is unknown by disk manager

Did you overwrite your original install? If not, you may be able to repair it. I would try to convert the current partition to NTFS, but that may not help. Partitions created by disk administrator can be difficult for another OS (other than the one that created it) to work with. You may be able to save the data using ghost to take a picture of the second partition, then wipe it out and re-create it and use ghost to replace the original data. That may work. Hope it helps.

I have this 160GB hard drive that I have not been using for a while, yet I am very sure it was working fine the last time I used it.

Today when I plugged it in to my new notebook that is running Windows 8.1 now, it doesn't detect my hard drive. I also tried on other notebook and it has the same issue. So I know the problem is most likely on the hard drive.

Using Command Prompt, it says Disk 1's status is "Online", but size is "0".

Here is the status at Computer Management:
Disk 1
Not Initialized

I also tried to Initialize on MBR, but it returned me with "Incorrect function." message.

I tried "Troubleshoot" and the result says:
"USB Mass Storage Device is an older USB device and might not work with USB 3.0
Plug the device into an available USB 2.0 port..."
My notebook has 3 USB ports where according to the manual, 2 of them are backward compatible to 2.0... I tested on each, but it is still not working.

What should I do? Although I have not been using it for a while, I wish to check the content first before formatting it. I might have some forgotten, yet important files within.

Thanks in advance. Hope I can be assisted here.

If the controller in the enclosure failed removing the drive and slaving it into a desktop PC may let you recover your files. If the drive failed there isn't much you can do.
