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

Question: [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:

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

Preferred Solution: [BOOTCAMP] Operating System: UNKNOWN on (Unknown) Local 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 (This link will automatically start a download of Reimage that you can save to your computer.)

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


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

Answer:unknown operating system

Have you tried anything else like defragment ?Your main problem is you are using ME . Sorry but it just won't work very well on some systems and there's not a lot you can do about it, or rather no matter how much you try it will always give you problems with some setups.There is nothing wrong with IE version 6 it's the updated version.Have you been using Windows automatic updates ? They can be troublesome with ME.You could try BigFix available from click here to update you system with the necessary patches.

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".

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.

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...

For months random local accounts have been popping up on my computer. I have never let anyone else use my laptop, I am the only user and my account is password protected. I would always delete these random accounts when I noticed them, but sooner or later they always reappeared. For a while a local account named Rebecca would continually pop up, and every now and then I'd see some other random users who would disappear after I deleted them, but Rebecca always came back. A short time before Windows 10 came out and I upgraded one of the random accounts kept reappearing, and at some point they replaced Rebecca. This is a local account named sdnftnmnax and ever since the Windows 10 update I have been deleting their account nearly ever other hour only to have them show up again. I don't know if any of these accounts are causing any harm or if they have access to my files, but it's getting really annoying and I just don't want them on my laptop.

Answer:How can I get unknown local accounts to go away?

It sounds like your computer is stuck in demo mode and is displaying the dummy accounts that go along with that.
Are you able to take it back to the store you purchased it from and have them exit Demo Mode for you. It would require whatever Admin password they used to set the device in demo mode.

I am involved with a small band of new user older generation silver surfers.A question that keeps cropping up, is the re-installation of the various operating systems, mainly ME and XP Home with a little 98se.They want to know [in printed form]what will or could happen if they inserted their operating disk in their computer.Would this re-install, reformat or destroy their system. This question came to light recently, due to the fact that a couple of people are having boot-up, crash or similar problems and they want to try some of the technical stuff themselves. Using the advantage of this forum may ease their concern a little.A warning as to what can go wrong or perhaps best be avoided, would be appreciated.

Answer:Re-Installing Operating Systems for the Unknown.

the worst that can happen is they may lose their data if they accidentally format the drive with disk, you should tell them to back up all important data before considering putting the disk in the drive, even if it's for something relatively simple, back-up, back-up and back-up again!!

My local administrator account password has evidently been changed to something unknown to me. I am sure I am typing the password correctly, I've carefully tried several times.

I have 3 local accounts on my machine and my Microsoft account (for purposes of this post I am not referring to that account as I never use it). 2 local accounts are "Standard Users," the third is my administrator account. The administrator account and one "Standard User" account passwords have changed to something unknown.

So, how do I change the password of the local administrator account? Can you even do that in 10?

I did see an online article that talked about Safe Mode that was pretty confusing, too many F8's being pressed.

I do have a recent image of my C: drive made before 1703 came into my life 2 weeks ago, which I can use if it comes down to that.

Was recently infected with virus and successfully removed it, thanks to information in this thread: straight to certain folders to ensure bad bad bad files deleted, and all were.But C:\Documents and Settings\Owner\Local Settings\TempContains a hidden file called x406THs3wg8XQNever appeared before. It's not being used by any programme. Read-only. 12.5 KB in size.When I try to delete it, standard message: The file 'x406THs3wg8XQ' is a system file. If you remove it, your computer or one of your programs may no longer work correctly. Are you sure you want to move it to the Recycle Bin?Googled "x406THs3wg8XQ": Your search - x406THs3wg8XQ - did not match any documents. I've restarted PC several times already (that includes restarting and turn-off/restart) to make sure certain things are okay, everything is operating properly, no errors in Event Viewer, but that file is an issue.Suggestions? Thanks in advance.

Answer: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).

Win xppro, sp3. ie8


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.

I loaded up explorer and opened up my C:/ drive to start a game in my program files, accidentally pressing "Downloads" finding this file there, my operating system is Swedish so the folder should be named "Hämtningar" (Swedish for downloads).

Recently my computer (Dell Dimension 8100, Win98SE) developed a problem with Outlook. I tried everything to resolve it, including uninstall and reinstall. I finally reformatted and reloaded everything. On the first time around it didn't automatically reload the chipset and I had never had that happen before, so I missed it completely and loaded other hardware before I realized that I had then screwed up the IRQ settings, so I reformatted and reloaded again. I also upgraded from IE 5.0 to IE 6.0.

I'm also having problems where if Outlook is receiving mail a Word document will not load until it is done. There is a severe delay in windows opening from one application to another at different times that I can't pin down.

Sometimes the screen doesn't refresh properly.

I had continual problems trying to install Shockwave and Flash, so I restored IE 5.0 and upgraded to 5.5. I now regularly have a problem with this. I can load the animated Flash egreetings cards, however, when I do the Shockwave Daily Jigsaw puzzle I get to the point where I click on 'Play Game', IE hangs and I got the following errors two different times:

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

Answer:Groove Shows Unknown Artist & Unknown Album

It's not something I've experienced and so I'm probably going to be of little help. However, out of interest do the actual song files themselves have metadata stored in them? For example, find the one of these audio files in Windows File Explorer, Right-Click > Properties > Details Tab.

If there is no metadata there, in Groove Music > Settings, is "Media Info: Automatically retrieve and update missing album art and metadata" set to on?

Also, do you have Indexing switched on in Control Panel > Indexing Options and the location where your music is stored (EG: Users folder) set to be indexed?

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

Answer:G510 SATA disk on Controller 0 Port unknown, IQRL not less or equal errors plus 100% disk usage

Maybe you can have someone analyze dump files and figure out what's causing this issue.  You can wait for one of the staff to reply or you can ask at Microsoft Answers as well.

Any advice? Thanks.

Then I ran ComboFix and Malwarebytes Antimalware and found nothing. I then used GMER and removed a virtual cdrom that had been sitting on my computer long after Deamon Tools had been removed. 
It is the proxy server that worries me. Doing a quick search of it there does seem to be a Trojan keylogger that will listen on that port.

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.


Answer: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.

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.

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.

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.

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

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.

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.

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.

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

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! ;)

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.

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.

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.

Is it because of a program I installed?
Do I have to remove it and how?

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 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.

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.

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 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 drive: Western Digital 250GB SATA / 16MB Cache - WD2500AAKX

Answer:Disk Management - Unknown / Not Initialized Drive

Have you attempted to run Western Digital's Data Lifeguard diagnostic software? It has a short test and an extended test.

Are you trying to recover anything from this drive? Or just trying to find out if it's broken?

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

Answer:External HD not Detected: Disk 1, Unknown, Not Initialized

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.

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 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.

Answer:HDD not Detected: Disk 1, Unknown, Not Initialized, Online

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.

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. It is 14.75 gb, and according to disk management, all 14.75 gb are free. What is it, and can I delete it without affecting anything else on my computer?

Answer:Y570 Unknown Disk 1 Not initialized/OEM Partition

hi galaxion2,first of all, do not delete the 14.75 gb partition. it's hidden/system partition that your computer will need to use it during one key recover process.secondly, as you noticed, disk1 is ssd.

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...

Thank you for any help provided, it is greatly appreciated from me and my laptop!

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 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!

My external hd appears in "Devices and Printers" under "Devices".
But cannot be accessed.


It finds the HDD, but "Partition Recovery Wizard" is not able to recover 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. 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.

Answer:External Hard disk not initialized, unknown.

"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"

Did you try initialising it as an MBR disk?

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


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.
