Preferred Solution: Unknown Disk

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: Unknown Disk

Bad hard drive, controller, etc.

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 resto... Read more

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.

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

Answer:Operating system (unknown) on unknown local disk

Welcome!

Try marking the C partition as active again, using the Windows method in my post here.

Then run Startup Repair from the repair disc. Hopefully it will see your installation.

Hi,Bought a G510 running w8.1 in May.  After 3 months of untroubled use I started getting all of the above error messages and problems. Restored to factory image. updated bios and updated drivers problems still persisted, all hardware tests were fine. Contacted Lenovo, laptop needed to be shipped to Germany, from UK as it appears there are no facilities in the UK??, to be examined.  The solution... Lenovo replaced the hard disk. Laptop was working fine again until a couple of weeks ago (about 3 months elapsed since original repair!!)  and exactly the same problems have returned.  The joke is I dont even use the laptop seriously as I dont trust it, and it spends 99.9% of its life as an expensive web browser machine. Surely the drive hasn't failed again, are they really that bad, or does the real problem lie somewhere else? Either way I'm totally unimpressed, no doubt having to send the laptop off for another 10 day holiday in Europe. :-( Anybody got any suggestions whats happening here?  Many thanks

Hi Admin,

I'm also facing the same like the rest of em with My WD 1TB external HDD, whenever I connect it, the computer recognizes it's being plugged in, however it doesn't appear in My Computer. When I go to Disk Management it comes up as "Disk 1, Unknown, Not Initialized".

I tried with the Partition Wizard mentioned earlier in the post, but seems it takes lot of time. Data inside the drive doesn't matter for me. If i get it formatted that would help.. kindly advise on how to proceed further.

Also am not seeing the option, New Simple Volume when selected the Unallocated drive.

If Initialize disk is to be done, what partition type has to be selected "MBR or GPT"

Please Help !! Thank you !!

Hi, My DVD Recorder died, so I took out the HDD Seagate DB35.2 and plugged it in my laptop. I get the above message in disk management. I also tried Knoppix 7.0 but the disk does not show up. My scope is to save the content in the disk and move it to my PC, is it a mission impossible? Any suggestion is very welcome. Thanks Alex

Answer: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.

I turned on my computer the other day and it decided to run a checkdisk. No problems, everything was fine. HOWEVER, the next time I rebooted, it said that there was a computer software problem and the exact error was "load dlls for kernel", please contact your support person for assistance. 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. If anyone can please help me, it would be HUGELY appreciated as all of my children's photos since birth are on this hard drive!!! PLEASE HELP!!!

Answer:Please Help - Hard Disk Unknown

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.

Hope this helps get you going.

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.

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?

Answer: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.

This 2.5" SATA drive is from a Toshiba that seems to have died this morning. There's no boot, no BIOS, nada.
I removed the drive and attached it via USB to my Win7 box where it shows as "Unknown, Not initialized, and offline." There are no rt-click options in disk management. I can hear the drive spinning, but it shuts down on its own occasionally, and sometimes won't power up at all without a bit of fiddiling.
I can't get any response at all from my Linux box, and neither Test Disk nor Recuva finds it at all.
Is there anything else to do, or is this drive dead, as I suspect it is?
 

Answer:Disk unknown, offline, not initialized.

If it's not being recognized properly, there isn't anything else that you can do.

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.

Answer: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.

Is it a virus because of a virus?
Why can't I access it?
Is it because of a program I installed?
Do I have to remove it and how?
Please help.

Answer:Unknown new hard disk drive.

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 drives....one 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.

I guess my first guess would be an external media player. If you have one plugged in, I'd unplug it from the computer and see if that other drive disappears.

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.

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! :)

Answer: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.

Hello Jenny, and welcome to Seven Forums.

What type of drive is it, and how is it being connected?

Please go ahead and post a screenshot showing the full layout of your Disk Management window to see if that may help ID what the issue could be.

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.

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. Thinking it would be easy, I decided to upgrade to a better drive so I purchased a 500 GB SATA Western Digital drive online (the old drive is a 200 GB SATA Maxtor) and tried to install Wi...

Answer:[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

Hi,

I've been recovering data from three older internal hard drives for a friend, by way of an external HDD enclosure connected via USB to my laptop. It went well for the first two HDDs but the third, well ....

It's a Maxtor DiamondMax 10 HDD, 120 GB and is also marked SATA150.

(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

Hi empog,

Welcome to Seven forums.

It could be an either an issue with the harddrive itself or it is formatted in a partition which is not recognized by windows.

Once the harddrive is connected open command prompt and type diskpart and hit enter. Then type list disk and hit enter.

Whatever information is displayed kindly post a screenshot for the same.

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.

I ran BIOS diagnostics on a Dell OptiPlex 3010 yesterday and received an error code (2000-0142) - short self test unsuccessful. I pulled the drive and swapped a new SATA drive to get the user back up and running quickly. I'm trying to connect the drive with the error to my laptop using a StarTech USB 2.0 to IDE SATA Adapter. When I open Disk Management I see Disk 0 (my laptop drive) and Disk 1 (the connected drive). It says Unknown / Not Initialized. When I right click and try to initialize it says "The device is not ready." I've tried the more actions > refresh / rescan. Now when I right click the option to Initialize Disk is grayed out and I can only see Offline and Properties.

I browsed through a thread from about 2 years ago and couldn't find a helpful solution.

We have a laptop that will not startup - 2 lights appear when trying but nothing happens. We need to get data back off it.

I removed harddrive from laptop and connected drive to PC USB with USB to Sata Drive Cable setup. It will not register in Windows Explorer. However, when I go to Disk Management, it seems to see something. It says there is a "Disk 3 Unknown of 465.76 GB" and "Not Initalized". In detail for that drive it says "465.76 GB Unallocated". It also displays a message when I fist enter Disk Management that says "You must Initialize a disk before Logical Disk Manager can access it". It offers initialization in either MBR or GPT partition style. The harddrive is stamped as a HGST of 500 GB capacity.

Listening closely it seems to be spinning. When it started up I did hear some other sounds but not a lot and it was very soft in all sounds - I had to listen very carefully to hear anything. And have not really listed to a drive before to see what sounds it should make. Also, I have not opened it.

I am running Windows 7 on the PC and the laptop was running Windows 8.

I have not initialized it as I assume it will wipe/re-format disk when I am trying to retrieve the data on it. Is it just the case of a drive letter conflict or is the drive just had it?

I am using windows 8 and I have read previous threads with similar issues that I face but my problem is unique. My 60GB external Hard disk was manufactured by FUJITSU and was taken out of a dell laptop.

However, the owner of the laptop removed the cable without safely ejecting the drive first. Later, I connected it to several computer and it would install and be detected in Device manager, Disk Management and even devices and printers but it does not show in My Computer nor does autoplay options pop up. In disk management it is shown as Disk 1 unknown not initialized as shown in the attached screenshot.

I notice that whenever i open disk management, it prompts me to initialize the disk but when i chose gpt and click ok, this window pops up

when I right click the Disk 1 the initialize option is gray and only offline, properties, and help are available. I used mini partition tool and this is what i get

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
Unknown
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.

Hi!
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!

Answer:[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.

I'm pretty sure I have some sort of infection, although I am not sure. My disk is constantly active, grinding constantly every second even when the computer is idle, no matter how much I restart or how long I leave it on. This has been constant for almost two weeks now and it is driving me insane. I did some research, tried to turn off indexing in case it was that, but that did not change anything. I did some disk defragmentations as well, but that didn't help. I have Avast, Malwarebytes, ThreatFire and Online Armor installed, but none of those have detected anything. From what I can tell by looking at the task manager, there is a process called System that identifies itself as NT & Kernel system that seems to gobble up 20% of my cpu in concert with the disk activity I am doing. When I try to locate that particular process though, it takes me to my desktop on explorer with My Computer highlighted.

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.

Since I have reinstalled the operating system the service pack right now is service pack 1.

Answer: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 am trying to recover data from laptop internal HDD use as an external hard drive to recover data from that HDD. I can't see my HDD in my computer but in DISK Managemnet, there is a message, "Disk 1 Unknown Not Initizalized"

Please Help!!

Thanks,

Answer:Recover Data from Disk that is unknown and not initialized

If the data is critical, and it sounds like it is.. the first thing I would do is use a software that makes a sector by sector backup or image of that uninitialized drive. That way if trying to make it readable by initializing it should hose it, you have a copy.

After that, if you know that the unititialized drive was at one time formatted NTFS then you might try initializing it with Partition Wizard freeware

But it may be worthwhile to talk to someone well versed in disk recovery. There may even be some dedicated forums around for that specialty.

If you get lucky and the Partition Wizard initialization shortcut works, then the files should be there after doing a non-destructive format as NTFS file system.

Assuming that's what it was to begin with.

Hi, I just got a new Y570 Laptop with a 64 gb ssd. In the disk management window, there are two hard drives listed. There is a disk 0, which has four partitions on it, and a disk 1 which is unknown and initialized. Disk 0 is the HDD that comes with the computer. When I try to initialize Disk 1, I get a message saying The disk cannot find the sector requested. What does this mean? Also, is disk 1 the ssd that I'm supposed to have? Another problem:On my hdd, I have an empty partition that says Healthy (OEM partition). It has no file system or letter assigned to it.

Hello,

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.

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.

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

Hi

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.

Please help!!! is there any chance i can fix this?

Answer:Please help,disk 1 unknown not initialized (western digital external)

I guess there is mechanical problem with the hard drive. you can try checking and repairing bad sectors (http://www.articlesbase.com/hardware...s-6907958.html), or just send it to some drive repair center.
but, if there is important files on the drive, you'll have to recover data before repairing it.

Hi all,
I've been searching the net and quite a fair bit of people have this problem but i can't find a fix to it. Also well reading through the articles, I'm not sure if it is a virus or if its something wrong with NOD32 software. I'm using NOD32 antivirus software and it keep popping up with this message "MBR sector of the 1. physical disk contains probably unknown TSR.BOOT virus Can't be cleaned."

The reason I'm thinking its a virus is cause my computer just froze and wouldn't go pass the user login. So i formatted the bootable HDD and the message was still there. I have 2 HDD both partitioned into 2 parts each. So 4 partitions over the 2 drives. I unplugged the slave drive and tried fixmbr and fixboot on the master drive. Booted up with the slave drive still unplugged and ran the virus scan with no virus found. So i turned off the computer and plugged the slave drive back in and booted up the computer and ran the virus scan again. There is was the same virus message.

So I'm pretty sure the virus is on the slave drive, but is there anyway to fix it without formatting? and even so would formatting and doing the fixmbr and fixboot solve the problem?

Please help its driving me crazy as the slave drive has files i would like to keep and theres like 250GB worth of stuff that i would have to back up.
Thanks in advance.

Hello. I am trying to reformat my computer and I have ran into a problem. i have tried to reformat using both Windows XP Home and Pro. When I pop in the CD and Boot from it all goes well until I reach the Partition selection screen. Instead of the list of drives and partitions I see this message in the box. It is repeated four times.

Unknown Disk

<There is no Disk in this drive.>
I am confused by this and i am not sure what I should do. i was thinking this could be caused by the fact that the necessary drivers are not present when I try to reformat, but if this was the case wouldn't I get the message before I even got to the Partition Selection screen? That has happened before and simple slims stream of the appropriate drivers fixes it just fine. So would a slipstream of the drivers fix this problem as well? I am hoping someone knows how i can fix this problem and have a successful reformat. This problem is on an HP Pavilion a1530n running Windows XP Media Center Edition. Thanks in advance.

Hi.
My external (seagate) hard drive can be detected, but it won't show on My Computer. I tried few options however the device is still not being recognised.

It appears in my device manager. I have uninstalled it, plug my hard drive back. It gets detected, but it still won't appear in My Computer.

It also appears in disk management. It's shows as Disk 1 Unknown, Not Initialised and the right column is blank.

I downloaded the MiniTool Partition Wizard and attempted to recover my data. I completed all the steps expect the last step as I can't right click to give the drive a letter.

I have important unbacked information on this device. Any help would greatly be appreciated. Thanks

Answer:External Hard Drive Not Detecting. Disk 1 Unknown.

Hello Liyah,

Your screenshots are two small to be able to read.

For now in Disk Management, see if you area able to right click on the smaller Disk 1 box in the lower pane, and click on an Online or Initialize option in the context menu. Afterwards, make sure the disk has a drive letter.

Hi everyone,

I need some help desperately with my Samsung 840 EVO 250GB SSD. Until yesterday, I had been using it for less than a year on a desktop PC to run a Windows 7 Professional x64 installation.

After it suddenly stopped working, it can no longer boot into Windows ("BOOTMGR is missing" is shown at startup), and it cannot be recognised in BIOS either.

I removed it and connected it as an external drive to a couple of other computers (a laptop running Windows 7 Home Premium x64 and a desktop running Windows 8 x64). Even though it showed up as a generic USB device in Device Manager and in the taskbar notification area, it did not appear as a drive in Explorer.

Disk Management showed the following screenshot, where it is listed as Disk 1, which is Unknown and Not Initialized. More importantly, because this seems to be less common than other similarly issues I've looked at here, the disk space doesn't even show.

I've since tried a few tools recommended in previous threads here, with no success:
PhotoRec - did not detect the drive at all
Partition Wizard (free edition) - the drive shows up as 0MB, so there are no partitions to work with
Power Data Recovery (free) - this actually crashes when I select either Lost Partition Recover or Damaged Partition Recovery

I really need to retrieve some data off the disk, and I'm hoping that's not impossible at this point. The fact that the SSD can still power on and (somewhat) show up as an external device is... Read more

My external HD is WD 1TB HD.. it does not matter if i lose the data..but i want the HD to work[ATTACH][/ATTACH]

Answer:disk manager shows DISK1 unknown and not initialized

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.

Hello,

My C: partition is 100GB large, I have already uninstalled every redundant program, leaving only the most important ones. I do not store junk like music/photos etc. on this partition, yet it's still jammed, at the worst point reaching only 300mb free space left.
 
I run glary utilities cleanup every now and then. It's always a max ~1gb gain.
 
Restore points and system protection are disabled. Hibernation mode is disabled. File indexing is disabled.
 
The fragmentation of the disk (HDD) has been assessed for 2%.
 
Windows Update is set to "ask before downloading and installing" for about a month. 
 
I have run DiskCleanup yesterday and it has found almost 9gb of space to free up. Today after rebooting the pc I've found my C: partition again almost fully loaded, having only 2gb left. DiskCleanup has shown only 30mb of data to be deleted. Glary has found only 500mb of junk.

Answer:Unknown Virus Filled My Hard Disk With Files

Hello elzosim and welcome to the BC HijackThis forum. I do not see any signs of viruses or malware in the log. It is clean.It is normal for many files to be in C:\Recycler. This is the folder used by the Recycle Bin. Whenever a file is deleted it is moved to the Recycle Bin so that if it was deleted by mistake it can be recovered (undeleted). Unless the Recycle Bin is emptied regularly there will usually be many files in it. They are stored there until the space that is allocated for the Recycle Bin is used up and then it will automatically delete the oldest files first to make room for any newly deleted files. This is normal.You can manually empty the Recycle Bin by right-clicking on it and choosing Empty Recycly Bin. Some people do this regularly and some never do it. It is up to you.Cheers.OT

This just popped up today and the only thing I can think that I had done since not seeing it was activated AHCI. As can be seen in the attached snip there is a very small partition to the left of the "SSD Common" logical partition. It is bounded by the same green box as the "SSD Common" partition. Hovering over it provides details of it being Free Space 1Mb in size. Right clicking on it provides a menu with everything greyed out except for HELP which simply opens the Disk Management user guide. Should add that both the "SSD General" & "SSD Trade" are W7 bootable partitions with AHCI activated.

Any insight is appreciated.

*edit* -- Oops, meant to place this under Performance & Maintenance.
*edit #2* -- there is also no reference to this 1Mb free space anywhere else on the disk management console (additional info since I failed in posting the full snip. ).

You could play around with it an extend partition F to the left with Partition Wizard. But why bother. It is such a small sliver.

Hi. I seem to be losing massive amounts of disk space extremely fast. All the problems started last week when my computer got drastically slower all of the sudden. I ran diskeeper and it said I was dangerously low on disk space and I couldn't figure out why. I ran a boot-time scan using Avast! antivirus and it found Win32:Trojan-gen {Other} in C:\Program Files\Google\Common\Google Updater\GoogleUpdaterService.exe. It failed to repair the file and so I deleted it and when I went back into Windows Vista after the scan, I had an extra 23GB of free space. At first I thought that everything had been fixed and so I proceeded to tighten my security so an incident like this wouldn't happen again. I turned on UAC and also downloaded Comodo Firewall (and turned off the builtin windows firewall that I had been using). Well unfortunately, I've noticed the disk space problem isn't gone because I've lost about 5 GB of free space just today. I've tried scanning again with AVG, Spybot, Ad-Aware, SuperAntiSpyware, Comodo's malware detection tool and they all came back clean. I tried freeing disk space with CCleaner but it only freed up about 300 MB. I then tried HijackThis for the first time and started deleting entries that seemed suspicious but it didn't help.

Sometimes the read-write heads will scratch the platters and they are then truly screwed up.

Hi -
I'm trying to install XP Pro onto a brand new SATA hard drive since my old one seems to have gone kaput after about 5 years.

I booted from CD, and went thru all the screens to the point where it was ready to start the installation. When i got to the screen to partition the "mass storage device", i got the following:

Unknown Disk
(There is no disk in this drive.)
Unknown Disk
(There is no disk in this drive.)

So i found an old post on this site (http://forums.techguy.org/hardware/823885-solved-unknown-disk-error.html) and followed the lessons learned there, and realized I had a floppy for a RAID DRIVER i had forgotten about (it came with the components I bought to build this box). So i tried the installation again, starting from a reboot, and hitting F6 at the right time. When it came time to install the 3rd party driver, i inserted the floppy as instructed, and hit Enter. The floppy light came on, but i don't believe i heard it do anything, and the screen asking me to insert the floppy quietly came back.

I tried a couple times, but still the floppy did not do its magic. I continued, and the partition screen still showed the Unknown Disk error. So as suspected, the driver did not get installed. I then rebooted, this time hitting F1 to check out the BIOS. My BIOS recognizes both my new hard drive and the floppy drive just fine, and the floppy itself can be read just fine on another PC.

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.

I forced a restart and made a system repair disc using another laptop (also Windows 7 64 bit). I booted with the disc and hit next on the language/country menu. Windows 7 showed up as a choice as my operating system, but I could not hit the next button (blue loading circle would replace my cursor whenever I dragged over the window). After a couple minutes, a window appeared that said something along the lines of "identifying disk." This window stuck around for about 5 minutes and when it disappeared I was taken to the system recovery options. On the top of this window it says "Operating System: Unknown on (Unknown) local disk." I do not have my Windows 7 i... Read more

Alright, so I bought a new portable harddisk, the samsung 3 1tb. However for some reason my pc does detect it, but is not able to run it. it gives me the error that it is an unknown device.

However, i tried the Hdd on several other pcs, and it worked fine, leaving me the conclusion that my pc is at fault. After recommendations from a friend, i tried to find myself some updated drivers for my motherboard, specifically usb drivers. However, my driver CD, aswell as the Asus site did not support my operating system (Windows 7, 64 bit).

So here I am, still unable to resolve this, hoping that any of you might be able to help me out. If you need any additional information, ill provide it asap.

I am trying to do a clean install of XP Pro(I have backed up every thing on an external drive) -my current OS is 2000 pro.This computer is only 3 years old and the manual for the motherboard says that it supports windows 98SE/ME?2000/XP. I get to the part in the installation where you are supposed to choose where to install XP and it says:
Unknown Disk (There is no disk in this drive)
Unknown Disk (There is no disk in this drive)
Unknown Disk (There is no disk in this drive)
Unknown Disk (There is no disk in this drive)
It won't even let me click on one of these without the blue screen coming up. The Stop Message reads:
0x0000008E(0xC0000005,0xF84CAD,0xF809E7E4,0x00000000)
I haven't updated the BIOS as I cannot find updates. And I'm not sure if my boot sequence is correct ? Any one with suggestions?

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. After playing a game, I left and came back to find the screen black, so I hit the hard restart button, and it got to the screen with the Gateway logo but when that ended and it should have flashed to the Windows Loading screen, it just went black with a blinking white _ . I tried hard restarting several times, and each time it would go to the black screen with the white blinking _. It shows the BSOD. Even trying Safe Mode only got me a little bit farther - I could get past the gateway loading screen.Finally I decided the best thing to do would be to reformat. Here is where my current problem lies. The drive is plugged in properly and is brand new, so I know it's not a dud. But, when I boot up with the Windows XP Home installation CD and get to the point of selecting which drive to install Windows on, the options is: "Unknown disk (there is no disk in the drive".Once again I tried to install Windows, and it gave me the same message (Unknown disk). I thought for a moment that maybe it was because the hard drive was bad, so that?s why I bought a new one. When the new one came in the mail, I put it in and the same problem happens.So now I'm at an impasse - neither of my drives, one of which worked fine not too long ago and one of which is brand new, is being recognized by Windows setup, and I don't know wh...

Windows is showing a Disk 3 that is not there. I'm not sure how it got there and I can't find a way to delete it.

Here is the screenshot from Disk Management

Answer:How to delete "Unknown Disk 3"

Really don't know what is happening and in the circumstances shoot all around in dark

1.Make sure you do not have any USB storage device connected to the front and rear ports. Sometimes a faulty pen drive can show up as an HDD..

2. Open Device Manager and check the disk drives shown. Also examine under USB for any unknown device.

3. No clues? Try Power cycling your PC. Remove all externally connected devices (except your Key board and mouse), shut down your PC and disconnect it from Mains pulling out the power plug. Leave it for about five minutes. Press the power button repeatedly a few times and hold for a few seconds to remove all charges in the PC. Power your PC now and boot.

Does your PC still show Disk 3 in WDM? Right click on Disk 3 icon on the left and check what Menu items you get and also check what it says when you try to initialise.

Win xppro, sp3. ie8

I REALLY WILL STOP SURFING PORN NOW

pops up new ie windows (not tabs) that link to random sites, often unknown search engines showing results for last string searched on google, often for other random things (news 6 live, adfat, sals barbershop). seemingly benign.

After some time of this, more serious infections occur, including antivirus soft, many others.

Malabytes will knock out what it brings in, but not kill the initial infection.

have run malabytes in safe mode, safe mode + neworking, and mutiple times after knocking out later more malicious infections in both safe mode and regular. Sometimes picks up a few stragglres, sometimes not. But in all cases I still have the original thing which pops up a new ie window to some odd thing and presumably opens the door for the rest.

Any help greatly appreciated, and, really, despite any other sex life to speak of, sad though that may be, I will leave the porn sites alone after this.

Please help me folks, I'm on borrowed time today.

I had to reformat my computer thanks to a handful of Trojans and of course, I am missing the Ethernet driver to connect. In the past, I had a friend set me up, but he never told me how to do it and he's gone in basic training so I can't ask for his help today.

I have a custom-built Compaq HP
I will have Windows XP HOME installed when I get the cash.

What I need is help figuring out where to look to find the model number to install the correct driver. I have tried the HP website and it does not work; My driver is built into the motherboard.

I currently have Windows XP Professional for English Students, it's my father's OS

I was in the process of updating several sata controllers and chipset drivers. I also installed a new USB 3.0 hub and was in the process of moving around several devices between ports. I had a problem with my keyboard which uses USB 2.0 as a connector but I would recieve a "Unknown USB Device (Port Reset Failed)" code 43 on every port on the USB 3.0 Hub. I finally gave up and put the keyboard back into the 2.0 ports on my motherboard. When I finally fixed everything. I realized my DVD drive was not working. I had to reconnect the SATA cables because it got disconnected while I was moving my PC around. Upon the last restart of my PC.

I checked Disk Managment and noticed lots of system reserved partitions and drives which were not there before. I have no idea what happened but I think updating several drivers and the combination of reinstalling USB ports via device manager or the optical drive being reconnected may have messed up how windows used to have system reserves as partitions. I only had one visible system reserved drive before, now I have 2 visible and lettered system reserved drives.

I also have a unknown partition at the top of the list, I cannot right click that partition and select any options. The only option in my context menu is Help which brings me a link to Overview of Disk Management

I also had my video quick access as my DVD optical drive when I restarted. I have fixed this issue by changing my quick access links back to their proper folders... Read more

Answer:Unknown Partition - Unknown File System - Cannot edit or remove!

Hello taqiyya6 Welcome to the Ten Forums!

Your problem is actually quite basic. You are going into the Disk Managetool and seeing system reserved partitions mounted and assigned drive letters where they shouldn't be seeing any! The 450mb partition is there to allow changing from the MBR type primary to the GPT type usually seen with server set up or large volumes exceeding 2tb in size such as installing and partitioning a new 2.5tb, 3tb, 4tb, or even one of the latest 5tb drives.

The sight of the System Reserved partition being present on the second Disk 1 500gb drive simply shows that had previously seen a Windows installation on it at some time likely before adding in the large 1tb Disk 0 drive you have the present install on. The most likely to succeed option for taking care of the smaller 500gb if nothing is on it would be a complete wipe and a fresh single partition intended for storage and backup. That would eliminate the first SR but not small second unless using an open source type partiioning utility like GParted while still an option to close up the small gap since it is only a 500gb and not exceeding the 2tb mark.

For cleaning the mess overall however going into the Device Manager and knocking out drivers before a full restart would allow Windows to redetect the drives fresh without seeing the System Reserved and MBR parts mounted again at least on the OS drive being the main concern since the SR part has to remain invisible as a system protected space not mount...
