[BOOTCAMP] Operating System: UNKNOWN on (Unknown) Local Disk

Q: [BOOTCAMP] Operating System: UNKNOWN on (Unknown) Local Disk

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.

Then I asked my neighbor and fortunately could borrow Windows 7 discs.
However it's x32, and HP, which I heard only works on HP laptops?

Now, I can boot from DVD and get to System Recovery, but are clueless as to what to do from here.

I have no knowledge in programming and stuff, so I don't know what information am I supposed to provide in order for others to guide me further, so please tell me what to do.

The best would of course be to recover back to how it was a week before, but at least I want to get access to my data in C: drive.

Just a wild guess but I believe the problem is on the Windows system and stuff but my data itself is only unaccessible but not damaged.

For now, I will list out how each options on System recovery goes.

System Recovery Options:
No operating system shown on the list.
No idea what to choose for "Load Drivers".
Local Disk (C:) visible but without the capacity bar(?) or any label.

Choose a recovery tool:
Operating system: Unknown on (Unknown) Local Disk

time taken = 375 ms

Root cause found:
System volume on disk is corrupt.

Repair action: File system repair (chkdsk)
Result: Failed. Error code = 0x1f
Time taken = 0 ms

System Restore:
To use system restore, you must specify which Windows installation to restore.

System Image Recovery:
Windows cannot find a system image on this computer

Windows Memory Diagnostic:
Windows cannot check for memory problems
An error is preventing Windows from checking for memory problem during startup.

Command Prompt:
For cmd, I tried too many things and didn't know what is what.
Willing to provided any results necessary.

Sorry for a really long post and thank you very much for spending your time reading through it.

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

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.

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.

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 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.
I don't have a recovery disk, but I do have 3 Windows backup disks I burned when the computer was new. I was able to get into BIOS and switch the boot order to load the DVD drive first, but it just asks me if I want to load the disk image, which I don't want to do since that'll erase my files and programs.
The option to choose a system image doesn't automatically detect anything. I have the option to select some drivers. When I open that menu, I can see that my two hard drive partitions (D and E) have their remaining space and files listed, but C is blank. I can open the contents of that backup disk (I just tried the first one), but I'm not sure there are even drivers on ... Read more

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.

I first noticed the malware a couple days ago about 5-10 minutes after downloading a chess engine called Thinker and opening it in a chess GUI called Arena. I had scanned the folder containing the engine with Avast before using it, but it said no threats detected. Earlier today I found a site called which scans a file on your computer with something like 53 different antivirus programs including Kaspersky, NANO, Malwarebytes, etc, etc. and all of the programs said it was clean except one called "ByteHero" which says it detects "Virus.Win32.Part.j". Anyway as I said earlier I noticed the malware 5-10 minutes after opening the engine in Arena when all of a sudden a page in my browser popped up for no reason, and soon after my screen turned into the screen that shows all users on your computer when windows loads. I immediately knew I had been infected and turned off my wireless connection and turned off the computer. When I restarted upon bootup I could immediately see weird things happening caused by the virus (I don't remember what was happening, it doesn't happen now). When I logged back into my user, I started task manager and saw a couple of the same or very similar thing under processes (again I don't remember what it was, but in the description I think it said something about "server") when I tried to end task it generated a blue screen.

A:Owner/Local Settings/Temp Folder - Unknown File

Some files are locked by the operating system or locked by running programs during use for protection, so scanners cannot access them. Files that are located in password-protected archives may also be locked or denied access. When the scanner finds such a file, it makes a note and then just skips to the next one. That explains why it shows as "skipped" or "Access Denied" in some anti-virus or anti-malware log scan reports. Similarly, when attempting to delete such a file manually, you may receive a message indicating it is in use or a warning that it is a protected. For more information about this, please refer to How to Delete/Rename a Stubborn File. Several utilities are suggested for dealing with stubborn files to include Unlocker.Please download Unlocker and save to your desktop.Choose the default installation folder C:\Programs Files\Unlocker, click "Next" then click "Install" and reboot when finished.Navigate to the file or folder you want to delete.Right-click on it and select "Unlocker" from the menu.If the folder or file is locked, a window listing of lockers will open.Click to highlight the file path and choose "Unlock all". (make sure "no action" is chosen in the program)After you unlock it, right-click on the file and choose delete.Note: When you are unsure about a suspicious or unknown file, you can rename it by adding .vir after the file's extension (i.e. badfile.dll.vir).

I reset Groove and made it scan the music directories again but the problem remains. Any solutions?

Hi, thanks for reading this and thanks for your help.

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

I remove my hdd from the laptop and put into a external drive i keep for this purpose, checking hdd?s.

I can?t find the drive in my computer but I can see it in disk managment. It says Disk unknown - not initialized.

I?ve tried using PW but i cant see the drive on there. I would really like to keep my files I have on that drive but it seems to me that it toast.


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.

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"

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!!!

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.

Recnetly I noticed I had a 4th hard disk drive instead of 3.
The strange thing is that I can't remember adding one..
I just got my 2 internal hard disk drives and 1 external hard disk. But now it shows 4.
Also, when I try to open this 4th hard disk it gives an acces denied error message.
When i look at it's properties it shows this:

Also, I'm unaible to scan the hard disk. For my other hard disks, when I right click, I got the option to scan for virus. This option isn't in the list when I right click this new station.
Here are the menu list by right clicking on the HDD's.

Where does this hard disk come from?
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.

A: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 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.

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.

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...

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

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'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.

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.

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.

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.

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.

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 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!

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.

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've got 600GB HD (Rock mobile disk) that goes without saying need to be recuperated. It was working fine earlier this summer when I last accessed it. A few weeks ago, I plugged it in again and it gave me an I/O Device Error, read and unspecified error.

I have been researching a solution non stop and today when i plugged it in once again something worst happened, this time I see a External HD not Detected: Disk 1, Unknown, Not Initialized in Disk Management.

Can someone please help?

The irony... we get an external drive to protect our data and not loose it and then this happens

Try this to salvage what you can from it: Download MiniTool Power Data Recovery Free Edition - MajorGeeks
Do that before any attempts to repair.
If nothing, portable drives are even less reliable than stationary ones and it's interfaces are prone to malfunction.

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.

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 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.

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!!


A: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.

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. When I bought a case for it yesterday it was tested in a laptop computer to see if it was working before I paid for the case and it was working properly. 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 am at my wits end. Please assist. I do not need what is inside the hdd. I just want it to work.

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. I need help before I throw my laptop out of the window because that noise is driving me nuts. Here's the DDS log, and I've attached the other two logs required as well. Also, when I ran GMER the first time my computer got a blue screen, the second time GMER crashed unexpectedly, and finally the third time worked, but the log file is too big for me to be able to attach 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.

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.

A: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

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 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

I've been having some very slow system issues today and have checked that system resources seem to be at normal levels - CPU usage at around 20% and Memory usage at around 50% during normal operating.

However I have noticed a new icon in my system tray which I can't identify, can't click on, and has no text when I hover over it. Can anyone recognise it? It looks like a grey/silver square or box with something green on it - no idea what it's trying to represent

Does anyone know what it represents?

Cheers, Smootus

I have a Seagate Goflex 500GB external hard disk. When I connect it to my laptop, it doesn't appear in my computer, and I have attached the screenshots of Disk Management and MiniTool Partition Wizard.
The hard disk is behaving this way when I removed it from my laptop while it was copying a file.

I do not need any data. I just want my hard disk to start working again.
Please help. Thanks in advance! High hopes!

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. ).

A:Disk Management displays unknown/unmanageable 1Mb free space

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.

Hello. Through the power of google, I have come here to see If I can get any help recovering data. Essentially found this thread: disk 1 is unknown, not initialized, unallocated and just having really similar issues.

Issue is with my sisters External Hard drive, a WD My Passport Elite 070B.
Asked her a few questions on how she was using the drive/any issues and she explained that she had to pull the usb plug while still reading/writing because it would hang/freeze (/facepalm)

Downloaded PW Minitool Recovery and EasyRecovery Pro Trial, but haven't really run any lengthy tests yet. Just tried them out for 10 mins to see if anything would show up. Going to leave the computer on tonight and do a full scan though.

Some other things I have tried:
-Tried connecting it to other PC's/Laptops(XP/Vista/Windows 7/OSX). Same thing.
-Tried different USB cables

Any suggestions or things I should try?

Hi all, Let me start off by saying i have spent the last few hours looking online for anything that would be able to help sort out my problem and found your forum the most helpful and the only one i have signed up to. So thankyou in advance.

I have a WD1200D036 (2.5 120GB external) that is not showing in My Computer nor was it showing up in DM but after going to device management\Disk Drives then Volumes tab and clicking on Populate it turned up in Disk Management as: Disk 1 Unkown not initialized. when i click on it and select initialize disk it opens up and asks me to select disk 1 and what partition style (I just sent with MBR) then click ok. It pops up with a error "Incorrect Function"

Any ideas??

I would suggest verifying the health condition of your hard drive first. You can use "WD Data Life Guard Diagnostic" to do that.

Download : WD Support / Downloads / Legacy Internal / WD RE2

The WD tool will list both your internal HDD and USB HDD for testing. Select the USB one and choose "Extended Test" to run. Let us know the test result in next reply.

I'm new to this forum.

My external hard disk (Seagate) is detected in the task bar after connecting, but not visible in "My Computer".

It is visible in Device manager under Disk Drives but not under USB.

There are few threads in this forum which are similar to mine, except that their Drives are visible in the Disk Management as Unallocated Space, mine is not.


I've tried all tools, tried in Windows XP still no solution.

Is there any way to atleast recover the data !!!!!!!!!

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. Then I found this site and it mentioned to not delete entries until someone can analyze the log. I've managed to restore all the backups except 3 because I deleted Bonjour and CVSNT and so the deleted serv... Read more

I am trying to recover data from my external HD 1 TB Fantom Drive GreenDrive. It crashed and I had no choice to force power down. When I look into Disk Management - I see that Disk 1 Unknown Size Not Initialized.

See Disk Man.JPG for printscreen of Disk Management.

I tried following the Mini Partition Tool advice and did not find the external drive on the software. Please see Mini Partion Tool.JPG for print screen.

I am thinking about buying another external HD 2TB and clone this drive to recover the data. Any advice to clone a drive that I cannot select.

Thanks in advance for your help!

It crashed

I've seen that and the HDDs had truly crashed, wasn't anything I could do but in a couple of instances I sent them off to a firm that recovers data if the platters/disks in them haven't been physically damaged. Sometimes the read-write heads will scratch the platters and they are then truly screwed up.

This quick new hard disk. So sad I cant access it anymore? why this happen?

You can see from the photo MY computer cant even see this driver anymore, so I check on the
- Disk management it said unknown no driver letter too ,Not initialized.
-Click Initialized it said i/o device error

I have try uninstall the device and restart let it install again still the same.
Checking many thread have the same problem, I wonder anyone solve this kind of problem before?
Update the possible cause of it, I believe my external hard disk spoil because my laptop was low battery and suddenly off either it goes Hibernate or off there is no time to read or write in the hard disk.
Then I just unplug the external hard disk.

If you face this situation don't unplug it, turn on the computer back and do a proper remove or shut down everything.

OK, I need help. This seems to ba malware related. I have tried to download and install several anti virus apps, (trend, eset nod, avg) and everytime I install them, I lose internt connections. The only way i am able to restore the internet on this machine is to do a system restore. I then tried to scan with super anti spyware, malware bytes, and root repeal, and the machine crashes evey time. I get the "recovered from serious error" message.

I have attached all of the logs I could. Again, I can not get one from root repeal as it crashes the system while scanning.

As a result, our backlog is quite large as are other comparable sites that help others with malware issues. Although our HJT Team members work on hundreds of requests each day, they are all volunteers who work logs when they can and are able to do so. No one is paid by Bleeping Computer for their assistance to our members.Further, our malware removal staff is comprised of team members with various levels of skill and expertise to deal with thousands of malware variants, some more complex than others. Although we try to take DDS/HJT logs in order (starting with the oldest), it is often the skill level of the particular helper and sometimes the operating system that dictates which logs get selected first. Some infections are more complicated than others and require a higher skill level to remove. Without that skill level attempted removal could result in disastrous results.
