Unknown Disk Partition

Question: Unknown Disk Partition

I believe i was attacked with a virus that messed up my OS booting. The Blue screen pops instantly after the attack. I restarted and the Blue Screen pops up again. I tried to load it with the settings that worked and the blue screen came up once again. I tried safe mode as well and still no change, same blue screen. As usual I thought a reformat would do the trick.I booted with my winxp cd and wanted to reinstall a fresh copy and i saw

Unknown Disk
(there is no disk in the drive)

Unknown Disk
(there is no disk in the drive)

I restarted the comp and rebooted with the cd and i ran the Repair Console
I typed in fixmbr to fix the issue. But the same Unknown Disk was still there when i tried to reinstall again. I did a chkdsk with Repair Console and the ' The Volume appears to contain one or more unrecoverable problems' msg appears.

I'm lost with what to do now

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.

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.
 

Answer:ntfs partition is unknown by disk manager

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

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


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

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


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


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

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

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

Hi

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

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

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.

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

Unknown Disk

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

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

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

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

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

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

Hello taqiyya6 Welcome to the Ten Forums!

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

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

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

I have a hard drive with XP Home on it that I need to get data off of after the partition blew up and now shows up as "Unknown" in XP setup and "RAW" in disk manager. The utility partition and recovery partition form the hard drive are still intact but not the OS partition.

I've already run chkdsk /r , fixboot and fixmbr to no avail. The hard drive ran without errors in HDAT2 and the IBM HD utility, no bad sectors or anything. When I ran fixboot it did tell me there was an error and it took 3 tries to write the new boot sector then I tried another chkdsk /r and still nada.

Anyone have a clue how to fix the file system so I can get this data off the hard drive?

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

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.

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

Trying to do a clean install and my Windows 7 Home Premium x64 seems to have an aversion to putting the system reserved partion on disk 0. My HP notebook has two identical disk drives. If I boot up the windows install with both drives unallocated and do a custom install, the window where i select the partition for the install if I click new to create a partition on disk 0, it creates one partition on the whole disk. If I do the same for disk 1 it automatically creates two partitions, one for the system reserved. If I try to do that in reverse order by partioning disk 1 first it will still create two partitions on disk 1 (one for the system reserved). It wont partion disk 0 with the system reserved partition.

I tried to install windows with only disk 0 plugged to into the motherboard and that worked when i partitioned the drive during the windows install it created the system partion on disk 0. However once i had windows up in running, I plugged disk 1 (unallocated) back into the mother board and windows woudnt boot up.

I could jsut install windows on disk 1 but ive read that it is better to install it on disk 0.

Answer:Clean install wont partition Disk 0 with system reserved partition

Welcome to the forum.

When you tried to boot with both disks installed, did you go to the BIOS and check that disk 0 was the first in the boot priority?

Answer:Creating A New Partition Or Wiping A Partition On External Hard Disk Stuck

I would check the manufacturers site for a windows utility to low level format it. If you cannot find a utility to do that on manufacturer's site, then try this: http://hddguru.com/software/HDD-LLF-Low-Level-Format-Tool/ to wipe the drive. WARNING!! this will destroy all data on the selected hard drive!! be very careful when selecting a drive to wipe that you don't inadvertently select the wrong disk. After a low level format, unplug the drive, plug back in, windows should detect as a new, virgin, drive and it'll prompt you to format it. Format it and hopefully everything will be fine from here on out for you.

Post back, Hope this helps!!

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

If your intention was to delete/format "C", why did you installed OS on the second partition ?. You could simply format the first partition and use it during the install.

Since there is no data to be saved, i would recommend a clean install as per this guide - Clean Install Windows 7

Basically you boot from the install disk, delete all existing partitions, create two partitions ( one for OS and other for data ) and choose first partition for install. If your OS is retail version, use the key for net based auto activation.

If your Windows is OEM, please follow this guide - Clean Reinstall - Factory OEM Windows 7
It is possible to format the "C" and run "Startp Repair" from install disc to fix the boot but it is always better to install and keep OS on the first partition. A clean install will also help you reclaim the space occupied by the 15 GB partition ( probably OEM recovery ).

I have a Dell Inspiration 6000 laptop. I want to repartition it having one 20 gig partiton for Windows and 15 gigs for Linux and the rest a FAT32 drive for them to share. Well I run Partition Magic and I can't run any of the Wizards because it says there are unmoveable partition on my drive. There are 3 primary partitions by default, one is a hidden FAT32 partition which I assume is used for system recovery. The other is called CP/M Concurrent DOS, CTOS which I don't know what it is.

So I can resize C and creeate an ext3 partition for Linux, but when I got to use the rest of unallocated space it won't let me create a new partition. Can someone tell me how I can create more partitions. And what is the CP/M Concurrent DOS, CTOS one?

Thanks.
 

Answer:Partition Magic: Unable to partition disk.

Figured it out. You click on the c drive partition and resize it, setting it to like 30,000 or 40,000 or whatever, leaving the rest unallocated. Then you can create a partition for it in the operations section and label it. Very confusing but it worked for me.

I tried to delete one of them using the Computer Management, however, instead of merging it with the system partition, it remains unallocated. Does someone knows how to solve this issue.

Answer:Hard disk partition with Partition Logic

Partition Logic runs from the CD. You boot it up. But I wouldn't use it. I have great hopes for such free apps, but I don't think that one is ready for prime-time.

Try the free Paragon partitioner (and make the CD after installation so you can partition from the boot CD, too).

The XP partition will need to be resized by a third-party partitioner.

I have a customer's computer here that has two hard disks, a 10GB and a 40GB. The 10GB is the boot drive and has been set up with Ontrack Disk Manager (part of Seagate Disk Wizard, both drives are Seagate drives), the 40GB is regular NTFS. The machine originally ran WinME but has been upgraded to XP. The problem is that Disk Manager comes up with an error on startup saying it can't find the operating system. I can't get into the 10GB drive to find out what's happened, it doesn't show up as a readable partition when I boot off a floppy or plug the drive into another machine. Partition Magic 8 reads it as a "Disk Manager" partition. When I boot off the XP setup CD it doesn't see any partitions on the drive. The most I've been able to do is run EasyRecovery over the drive using the RAW partition type (i.e. it doesn't find any files as FAT32 or NTFS), which allows me to extract all the files, but without the filenames or directories. Spinrite seemed to find a bad sector when I did a level 2 recovery, Seatools found no errors on the drive.

Does anyone know how you can copy files off a drive that has been set up with Ontrack Disk Manager? I installed ODM on a workshop computer but it doesn't seem to have any feature that lets me convert the drive to a regular partition format, or extract files from it.

Hi,

Has anyone tried to resize a partition of a SATA disk with Acronis using an USB enclosure? I forgot that I tried once awhile ago, and it took an extremely long time. Of course this makes sense, given the limitations of USB.

But I forgot about that previous experience, and found myself in a position where I needed to resize a partition on a drive. My desktop is down at the moment because the raid controller failed and a replacement is on the way from LSI. So I thought I would use my laptop and put the drive in an enclosure, instead of taking 5 minutes to setup a disk to boot into on my desktop which was dumb. (because I have an extra disk with an installation for it...)

Anyway, I forgot about the problem last time I tried over USB, and as soon as I clicked "commit" I noticed the 18 hour estimated completion time. I clicked cancel, hit "yes" to confirm the cancel, and nothing happened. It's about an hour later, and it is still trying to resize the drive, and hitting cancel still does not actually stop the process.
Does anyone know what is going on?

If there is data on the partition that is being resized, will terminating the program via end process in task manager before it is complete corrupt the data on that partition?
So I'm looking to have 2 questions answered:

A.) Does anyone know of a method to get Acronis to cancel the partition resize?

I don't have another 15 hours to wait. I need to leave in an hour, and need to bring my... Read more

I'm thinking you should've waited ... the first estimate is always ridiculously long ...
But once Acronis figures out what it has to do ... The time usually drops to something more reasonable.

Hello, Initially when I re-formatted my computer to get rid of the factory image, I found that there was a hidden partition of 1.37GB which I could not touch, meaning i could not delete. I ignored it at that time and formatted my computer and reinstalled vista business on it using the license i got from lenovo. Now after some days, I was kind of getting concerned as to what exactly was the 1.37Gb partition on my computer. I guess I was getting worried as to why I was not able to reclaim that space for normal use. Today, I tried to reclaim it, by deleting the volume, thinking it should merge into the unallocated space, that I have on my primary hard drive. But it did not. However, what happened was that this space of 1.37GB did start showing up on My Computer, once I formatted it using NTFS. I then checked its properties in My Computer and it had an option of readyboost. I selected the option which says use this disk for readyboost, and immediately in no time, the disk was full with on 68MB remaining as free space. It also has an icon of readyboost in the drive, when I double-click it. This is when I figured that this space could be on a separate physical disk. I did some research and found out that this drive or device or chip, is listed as Disk-1 in disk management and as IMD-0 under Disk Drives in Device Manager. I googled about it, and found that it was related to the turbo memory. Now, I believe that turbo memory would be a separate flash chip, which would be hardwir... Read more

I am running Windows 10 Pro.

I have an old 1Tb drive that used to be the boot (C) drive and also had partitions for two additional drives.
I since replaced that 1Tb drive with an SSD and another 2Tb second internal drive.

I've inserted the 1Tb in an external USB SATA dock. In Disk Management I was able to delete all the data volumes on the 1Tb, which then formed two unallocated sections, but there are 4 other partitions that I was not able to deleteDiskMgmtScreenShot.docx.

I then tried to convert the drive to a dynamic disk, but got an error saying "The operation is not supported by the object."

See attachment for screen shots.DiskMgmtScreenShot.docx

Is there any way to just reformat the entire drive, or to remove the partitions? I don't see FDisk in Windows 10.

How about putting this drive in the internal bay, and attempt to reformat it with the Windows 7 install disk, and just tell it to remove all partitions?

Answer:Unable to convert 7 partition disk (basic) to dynamic disk

Open Admin command and type:
diskpart
select disk 6 Note: your doc shows this as disk 6, if different then change it to the correct #

exit

Open disk management and initalize the disk then format.

Hi, I have laptop with system (199mb), windows, recovery and tools, so the 4 primary are taken.
I created another partition in unallocated space, and it converted the disk and all partitions dynamic.

If I image the windows partition with macrium, convert the disk back to basic, and restore the image, will it work 100% as if it was imaged on a basic disk, or does the fact it was imaged on a dynamic partition change anything in the image?

Also, can I just move all the folders and files from the system partition to the windows partition, and just run a start-up repair in macrium or paragon, and it will make the windows partition active and bootable?


Thanks.

Move windows 7 installation from one disk partition to other disk partition
HI all ,

Before going into details of my problem, I am listing down my system setup.

I have 3 HDDs on my pc with following details :-
1. Disk 0 - 500 GB - Windows 7 32-Bit Installation on C: - Partitions ( C - H)
2. Disk 1 - 1 TB - Windows 7 64-Bit Installation on J: - Partitions ( J - N)
Here I want to mention that, my Win 7 64-Bit installed on J: , and my linked documents folders reside in K: under folder K:\MyFolders ( as shown in K_myFolder.jpg)
3. Disk 2 - 1 TB - No OS on any partition - Partitions ( O - T)
As shown in attachment DiskMgmt.jpg


Now my problem is, windows 7 has detected some fault in Disk 1, thus I need to send the Disk 1 for RMA. So for the same I need to move my Windows 7 64-bit OS installation from Disk1 - Partition J: to Disk 2 - Partition O:, and data folder Disk 1 - K:\myFolder to Disk 2 - P:\myFolder.

How can I do with keeping the settings as mentioned above. How does my OS References will be remained for the requirements.

Thanks in Advance.

Answer:Move windows 7 installation from one disk partition to other disk part

We need to see the labels which are obscurred in the Disk Mgmt columns, nor can we see how much space is used on K you want to move to the smaller P.

You want to use Disk Imaging.. I would use free Macrium Reflect which offers more flexibility where to reimage the partitions you choose to image. Macrium - Image your system.

However if you have a WD or Seagate HD in the mix, you can use their premium Acronis imaging app which is best of all, and has a very easy to understand Manual on it's download page on either HD maker's site.

After imaging if the OS fails to start on the new HD, unplug all other HD's, confirm the OS is marked Active, then run Startup Repair - Run 3 Separate Times until it starts and holds the System flag. Then set preferred HD to boot first in BIOS, boot other one using one-time BIOS Boot Menu key.

Running a freshly done re-install of win 7 64 bit.

I'm working on bringing the newly installed machine up to speed, and want to do it like the old OS that lasted 5 yrs was done.

That is, I broke the main OS disk into 2 pieces... so three total since the OS takes a tiny 200mb partition.

I guessed a good size would be 150 GB for the OS... 5 yrs ago. It turned out to be a bit close by the end of its career and was only 34GB shy of 150 GB.

So this time I thought I'd give it another 40GB making it around 190 GB.

So, cutting to the chase:
Using the OS tools, it appears the disk manager wants to keep around 250+ for the OS. I cannot see why this would be the case.
I have some screen grabs at the end showing the shrink dialog, and snap of the properties of the disk.

And know too that I have:
Tested and De-fragmented this disc, and it has been freshly reformatted too. All not long before starting work to shrink it.
The dialog (see image below) shows (Sz taken direct from the tool. Conversions from : Convert gigabyte to 248006 megabyte - Conversion of Measurement Units )

. . . . . size before shrink: 476838 - 465.66 GB
. . . . Shrinkable amount: 228832 - 223.47 GB
Total size after shrinking: 248006 - 242.12 GB

242 GB seems a bit hefty for the OS partition given the fact that it topped out at less than 150 GB after 5 yrs of use.

I'd really like to pare that down... but a little hesitant to get after it with Partition Wizard or the like.

So, I'm asking if I should h... Read more

Answer:Using win7 Disk manager to shrink disk... leaving partition too big

I'd think only you can decide how much additional space you need, both for application programs you plan to install eventually as well as for any data those programs may manage, not to mention other documents and files you currently have or plan to have in the future.

I myself have three internal hard drives in my "small" machine, divided into partitions C-M. This structure has evolved for many years, and I know exactly the type of data I put on each partition. C is obviously primarily for Windows and programs, along with miscellaneous "data" that's kind of generic. Any other data that is significant in size or numbers (e.g. multi-media audio/video/pictures) go elsewhere, as does important "work related" data. I've never bothered to try and move "\My Documents" off of C, I simply SAVE data to other partitions when given the opportunity.

Anyway, I agree with you that a "minimalist C" in the real world doesn't need to be much larger than probably 75-100GB tops, assuming you have someplace else (like a second partition) to store your REAL (or really large/numerous) DATA files, and assuming you're conscientious about SAVE'ing your data to those other partitions rather than just letting the target location default to say "downloads" or "\My Documents", etc.

Here's my "small machine" setup. Note that I'm only using about 64GB of my C-partition, of which the Windows 7 Pro x64 folder itself is 29G... Read more

Hi all,
Hope someone can help.

Recently I was running this program to decrypt a ps3 hdd but this required an addition hdd to be formatted with x0xx or something. instead of choosing the other hdd i chose my C: which i was using at that time.

after 3% my laptop shut down then i realised that i done something wrong.

I tried to format my c: instead of the other drive.

I have a files and folders of huge importance in there.

I connected the hdd using a sata-USB cable to my sisters laptop and on the disk management window it shows as...

L:
layout - simple
type - basic
file system - used to show 'RAW' but now blank
status - active (healthy, primary partition) 4
capacity 74.53gb
free space 74.53

fault tolorence no
overhead - 0

I cannot remember if this was originally a fat32 or ntfs.

When I start my laptop it says 'no operating system found.
I went into recovery console andtriewd fixboot and fixmbr but it still wouldnt load up.
on winxp installation window, it shows this partition as unkown.
I have used several data recovery programs and found some files but they are not in the right order and does not have the proper file names.

is there any way I can go into the hdd and recover the data by folder names.
or can i somehow reinstall windows without formatting and then i can access the files and folder.

Please help me

Answer:unknown partition?? help :( :(

Well, it looks like you formatted the drive for sure. Pull the HDD out and put it on your sisters computer and try running Recuva or GetBack for NTFS to retrieve your lost files (pictures, Music, documents etc) and save them to her computer. Once you have recovered everything you can from that drive, put it back in the computer and install Windows XP.

Question: partition unknown

I have a problem with one hard drive and one one USB stick.
Last week I could not access the USB stick and it was listed in disk management as "Healthy Partition unknown". Today the same thing happened to two of my hard drives. the first partition on one of them and the entire second hard drive are inaccessible through normal means (like explorer) and show up as "Healthy Partition unknown".
Luckily I got all my data back by using the "Recover my files" utility,
but the drives are otherwise useless.
Incidentally these were FAT32 partitions, but I do have an other drive with the same FAT32 format and is so far not effected.
Do I have virus? or what caused this?
The system is XP SP 2 all security updates.
AVG antivirus, Comodo firewall.
Everything else is working normally.

A couple of years ago I uploaded Ubuntu and experimented with using it as an operating system for my VAIO laptop. In order to do this I partitioned my hardrive and for a while ran a dual boot system. I didn't take to Ubuntu and decided to stick with Vista, so I deleted it and attempted to delete the temporary partition on my hardrive with no luck.

I have sat on this problem for years, occasionally trying to solve it to no avail. Now my main C drive is nearly full, only 5.59 GB of free space and I need to access this unused partition space and the 9.31 GB of potential it contains. But still I cannot delete this partition, it should be sooo easy, but my system is not operating as text book.

I am in Disk Management, in Computer Management folder.

It is a basic type partition, simple layout that says Healthy(EISA Configuration). But when I right click the mouse over the partition I want to delete, the only icon that pops up says 'Help', it doesn't give me the option to 'delete, shrink or expand volume'

Now I have tried lots of suggestions from the help section, but can't seem to solve why my computer will not allow me to access the necessary options icon to delete this partition.

My company's computer needs to be patitioned and reformat. The system is still working well. I mean, nothing wrong with anything (weird huh?). Ok the hard disk just need to be 'split'. I mean, make drive C & D on the hard disk. I know how to do that... easy... Then the HD need to be formatted & reinstall windows XP. Ok, easy too..

But the main problem occured before I do anything (partition & format). I have my own bootable CD that I usually use for partitioning & formatting.

Ok, i insert the CD & restart.
I went to BIOS & changed the boot order (1st boot: CD-ROM, 2nd: HDD-0 & 3rd: Floppy). Then restart again.
Ok the bootable CD is excellently loaded.
I typed fdisk, then came the first problem. it says something like 'no fixed disk'. I exit fdisk.
Then I typed format c:, 2nd problem occured. it says something like, 'invalid drive'.
I forgot the error message because the pc is in my office right now. I'm currently at home 'begging for help' So the error message is not accurate. sorry..

I think, if I run the CD, the hard disk will not be loaded (or should I say, hard disk failure). & If I take off the CD & restart again, change the BIOS (1st boot: HDD-0) then windows will load! Weird right?

I don't think my CD is 'corrupted' nor broken because I tried to run the CD from another PC. Yes, I can access the C drive from that PC.

Answer:Can't format hard-disk nor do partition when using boot disk. Hard-disk failure

It sounds like it might be the bootable CD you've created is not picking up the HDD's/partitions.
To eliminate this as a posibility travel to bootdisk and grab the WinME bootdisk and boot from there. If it picks up the HDD you can FDISK and Format from there.
The other option is to boot using the XP CD and let it handle the formatting/partitioning duties...

Hi,

I have a laptop (packard bell easynote) that I use every now and then just to play games. When I bought it it came with windows vista already installed and frankly I'm getting tired of it and so want to downgrade to XP.

I inserted the windows xp installation cd in the dvd/cd drive and restarted it....etc....to get the issue at hand here -> I'm right now in windows xp proffessional setup (in the middle of installing xp) I have deleted the partition where vista was installed and am about to make a new one to install xp in but there is another partition there

F: Partition1 (_OEMBP) [NTFS] 8197 MB ( 2196 MB free)

I'm not sure what it's there for so this is basically why I'm here. Should I or should I not delete this partition? It's taking quite a bit of space so that's why I ask. I have looked around on the net for a description but nothing so far so why I decided to ask my own question.

Answer:[SOLVED] Unknown partition

Hello Alerno

Welcome to TSF

This partition is your built in OEM partition, this is where your computers recovery software is kept. Now because its OEM this means that it came pre-installed with vista and alot of free and trial software, so if just say, there was something wrong with your PC,you could boot into the recovery console and restore back to manufacturers settings using this partion

It is always good to keep this partition as you can use it to upgrade to vista again if you change your mind,

I do stupid things like this on a Monthly bases and I usually just reinstall Windows 7, however I broke the disk and now don't have one, plus I have important Files on there that I NEED.

Now to What Caused the Problem:
Today while installing a Game, I didn't have enough space to install it on Windows 7, and I had 100 GB for Ubuntu (Didn't think I would ever use 100 GB for Windows, but I did), So I deleted the Ubuntu Partition and added it to the Windows Partition. After Installing the Game I decided I would restart my Computer, and when it was starting I got the "No Such Partition" error.
( So I used Ubuntu Live when it wouldn't work to find out the prob.)

So then I figured I would Reinstall Ubuntu on a 20gig Partition. So I started the Install, and it had an Error (I'm assuming it was because the disk was dirty). I figured I would clean the disk and try again, so Did that, went to install, however the 20 Gigs I was going to have it use was a Unknown Partition. Not wanting to not use it, I figured I would find another way to fix Windows.

So I borrowed a Windows 7 Disk from a Friend to use it to Repair Mine, but it was for the Wrong Version so it wouldn't fix it. However I found a way around that and Used the Repair Option (I figured the Problem should be an easy fix), and So when I finished I restarted my Computer, Now I get "Requiered Device is Inaccessible", Status 0XC0000225.

Answer:Windows is now a Unknown Partition.

Bit confused, which OS was the primary one, was this a dual boot ?

What did you use to re-allocate the 100G?

Either way I'd download a copy of the Ultimate Boot CD V5 (obviously on another machine) and get it burnt to disk, there are tools on this disk for accessing pretty well any kind of hard drive. You should at least be able to check the partitioning (DO NOT try to fix unless you are absolutely certain you know what you are doing), there is an application on there called Parted Magic that should help you get your files back at least (Ultimate Boot CD - Download the UBCD)

Alternatively buy another hard drive, get yourself up and running on that, preferably with a Windows OS and install the 'failed' drive and see if you can access it, this I think will be your easiest initial option.

The most important is to stop messing about with the failed 'OS' disk, number one priority is to get your files back, the more you mess around on it the less chance you have.

Either way you should consider the failed 'OS' disk off limits for rebuilding or rebooting with until you get your files off.

Hi all,


It happened all at once, I restarted my asus K52E with windows 7 x64 and a black page with a blinking underscore was shown, indicating a damaged mbr.

The recovery partition is not accessible. I tried all the Win7 mbr recovery (with the command prompt of the win7 installation disk) but didn't work
Moreover, I'm afraid of my data partition, because this one is the only not readable by the ubuntu live cd. I post here my HD partitions:
ImageShack? - Online Photo and Video Hosting


I explain:
dev/sda1 is the asus recovery partition (cannot access it)
dev/sda2 (C:\), is the ntfs win7 installation partition
dev/sda5, is the ntfs data partition (I WANT TO RECOVER)

please, how can I access the sda5 partition or boot my pc without hurting the files in the data partition ?
Do you know any bootable SW?

thank you,

Fred

I have a 20GB hard drive with windows 98 se loaded. It also has Go Back loaded. So every time I boot the computer, Go back starts first, then windows kicks in. Well, recently Go back seems to be locking up, so windows can't start. I restarted the computer with a windows 98 startup disk to get to a "C:" prompt. The disk indicated that there was no hard drive. I ran FDISK to see. FDISK indicated that there was a hard drive but it had an unknown partition type. I NEED the data on this drive! Is there anyway I can get to the data? Can I change the partition type to fat32 without losing the data? Is there a utility I can use?

Thanks
Ray
 

Answer:Unknown Partition Type

It's been a while since I've used 98 (SE?)

Boot with the floppy and go to your a: drive, then type in dir and press enter.

Somewhere in there are scandisk and utilities that may help.

i needed more hard disk space, so i cloned a 10 gig hard drive to a 20 gig hard drive. i booted up with my 250 gig as slave and my 20 gig as master. it booted up fine, and i had 10 gigs free space. the only problem is, my 250 gig (D) wasn't there. so i went into administrative tools

after going into the disk manager i saw that the western digital 250 was there, but aparently it was an "unknown partition (healthy)", which is weird cuz BIOS recognizes it and partition commander sees it as NTFS and can access the files, and i scanned it with SMART and partition manager and it's apparently fine, but windows doesn't recognize it right

i think im gona buy a hard drive enclosure and see if windows sees it fine through that. will that work, or are there alternatives, or what??

----UPDATE----

i got the hard drive enclosure and windows does pretty much the same thing. it works with different hard drives too.

Of course, I am on w8. I have a 1 TB single hdd on my system, with
C 100 GB w8 boot,
D 100 GB w7 boot,
E 100 GB having all my info and data.
F remaining 600+ GB empty.

All are primary partitions.

I want only my E partition data to be backed up or mirrored or cloned or synced or imaged or copied (don't know the correct term) to a part of F so that whenever I make any changes to anything in E, that is automatically always reflected to that back up of E in F.

If automatic syncing is not possible, it will be ok if I have to run that software daily once or schedule it to get it automatically at a fix time of the day.

I have tried w8 imaging or backup but they do this in some cryptic method so that I am not able to figure out how to restore any particular file when I needed it. I need just an exact replica of my E folder-file structure to be made to a part of F.

I don't want C (w8) or D (w7) to be touched or changed or backed up or anything at all to be done to them.

Please suggest any free software or something built into w8 to achieve the same.

Thanks.

Answer:DISP:Partition Unknown Format

May I ask... what it is that you are trying to do with an 80GB HDD and 6 partitions? Or, is it Windows that is setting up these partitions? Windows does set up at least one partition for the NT kernel. Are you sure that they are all, in fact, HDD's and not CD/DVD/USB, etc... ?

Dear all,I am running Windows 7 home premium. Sorry for the essay, but I'd like to fully describe my problem!I believe I have a rootkit issue. It came from a downloaded video which had a corrupted time-base, and once a certain point in the episode was reached, my PC crashed and rebooted. Initially it started as before, but I very quickly started to receive the typical "your computer is infected with malware - buy our software", or "your hard-drive is corrupted!" scare-type messages. Also desktop icons were lost, and my start bar was changed in a few ways.I deleted the infected video, ran Rkill, malwarebytes and then unhide. I typically have 2-3 processes killed by Rkill - almost always the following two: * C:\Windows\DAODx.exe (PID: 2220) [WD-HEUR] * C:\Windows\system32\lxdncoms.exe (PID: 3556) [WD-HEUR] (I would like to add that I do not have a lexmark printer, have any printing software installed, or has this PC ever been connected to any printer!)The computer was (relatively) stable, the icons were recovered and I am able to open software (.exe). However, the start bar was left before, for example icons on the bar are listed rather than stacked, and the system tray does not auto-hide. I don't know if these are options which I can replace, but so far I can't find them.In order to try to return to normal, I tried to run windows' System Restore, to a restore point before I downloaded the offending it...

Hi all,

I had a virus so I reformatted the partition that had my OS (XP Home). I left the other partitions intact, but I realized after I reformatted that 2 of them were logical (1 xp, 1 ubuntu). I reformatted with XP Pro and now I can?t access the xp partition and the option to boot into ubuntu is gone. I just read that XP pro and home formats aren?t compatible (http://www.bleepingcomputer.com/forums/index.php?showtopic=99028&hl=dskprobe), but I don?t think that?s my problem (yet) since I don?t have the ?Foreign Status? in disk management.

I?m guessing I screwed up by overwriting the MBR on that first logical drive? Disk management shows ?Unknown Healthy Partition? for the 2 partitions in question. I?ve heard about dskprobe.exe, but can?t find any resources on how to use it? I have read that you can really screw things up though. Anyone know of any guides or other software I could use to access those partitions?

TIA!

Okay,

Let it be known that I have done this before for many years on many different computers, and never had this happen before.

so here's how it went. Bought it two days ago, PC came as is with OS loaded with software that I didn't need or want. Decided to re-format, now I get a butt-load of errors during install. (80+ at most, and never the same).

Formatted NTFS on the two HDD's I have, rebooted, Primary Unknown, Secondary NTFS, booted recovery console and ran FIXMBR and DISKPART and both said NTFS. Booted back into XP DOS setup, primary unknown, secondary NTFS.

Tried install on secondary MBR, same 80+ errors and that's when I had to head to work.

If anyone has any ideas, please reply, will check in tomorrow.

it's not the HD's, I just bought one of them and the other was booting XP before all this. And I don't think it's the board, because it would not have booted XP in the first place

Answer:CPU Usage always 100%, All security features disabled and unknown partition

An update,

I detirmined that I had rootkit on my machine and I got it cleaned. Once I got that cleaned some of my security features came back, my antivrus being one of them!

I ran my antivirus and it detected over 3000 infected files with a Win32 virus, I then deleted and disinfected these files. I think this virus infected everything it could!

However, I think i may have deleted some files that I shouldn't have as my all my network adapters are now showing a yellow ! in device manager and have error code 39. This has disabled my connection to the internet! There are also other applications such as chkdsk that can no longer be found.

I have recovered some of the files using the antivirus backup, but I do not know the locations of which ones I need to restore the drivers and chkdsk etc, with over 3000 possibilities where should I concentrate my efforts? If I uninstall the drivers will they reinstall themselves on restart?

I'm getting there slowly, any advice would be much appreciated.

Today, my notebook crashed (BSoD) while playing an online game - Team Fortress 2. It happened a few times before and, with a little research, found that other users with my video card had the same problem, so I thought nothing of it. After the most recent crash, on reboot, I get the message that "NTFS.sys is missing or corrupt," and I can't access Windows at all. I can get into BIOS fine.

I tried using the Recovery Console to copy NTFS.sys to my Windows\System32\Drivers folder, but Recovery Console isn't recognizing any files or folders on my C: drive. When I enter the DIR command, I get the message "An error occurred during directory enumeration." If I access the D: drive, my extra partition shows up just fine, and I can access all the files I've stored on there.

When I boot with my Windows CD and look at the partition information, I see the following:

-: Partition1 (EISA Utilities) 4997 MB ( 355 MB free )
C: Partition2 [Unknown] 54486 MB ( 54486 MB free )
D: Partition3 (Storage) [NTFS] 54988 MB ( 1141 MB free )

Although the count and free space for drive D: is accurate, drive C: isn't even close. The total is correct, but the actual free space is around 8-10 GB.

Hi.

A while back, a friend of mine partitioned my hard drive and added in a virtual machine for Windows Vista, which was 100 GB in size. This was fine at the time, however now my Windows 8 seems to be randomly shrinking. Over the past few weeks I've lost about 100 GB and I can't understand why. I'm still actively investigating, but I'm now down to 39 GB free of over 400 and to tide me over until I can find out what's happened (and why) I want to remove 50 Gb of my Windows Vista and add it to my Windows 8.

This sounds like a really easy thing to do, but... the problem is that they are on two completely separate hard disks. Disk 1 contains Vista and Disk 0 contains the rest. I do have another couple of questions about removing certain unnecessary partitions on Disk 0, but I'll wait until I get this solved first.

To start with, I shrunk my Vista down by 50 GB, and then I attempted to simply move it across to the C drive. But it wasn't until then I realised that that it wasn't going to be as easy as just merging partitions or even just 'extending' my C drive.

I have also downloaded this tool which has helped me understand slightly more what's going wrong, but I'm still struggling to understand how it can be done. I've searched and have been unable to find any kind of answer on this; people either seem to give up or it isn't related to my issue. I'm not sure how well I've explained this, so I'll also attach a screenshot of the Windows partition manager so you can see what exa... Read more

Answer:Moving Partition from 'Disk 1' to 'Disk 0'

Of course you cannot add partitions from one disk to another. A 500 GB hard disk is a 500 GB hard disk whatever you do, it will not become a 550 GB hard disk by adding 50 GB from another disk. You don't get a three liter Coke bottle by adding a one liter bottle to your existing two liter bottle. It's impossible.

I don't see any issue here; use the free space on disk 1 as storage space for your Windows 8. Simply create a new partition using all unused space on disk 1 and store your files there. You can create totally normal folders there and for instance add those folders to your existing Windows 8 libraries.

hello everyone,

ok so I have a vaio vgc-rb64g desktop (giving to me by a friend) and im trying to get windows xp installed on this thing. At 1st the original hard drive came up as unknown disk when i tried to install it. So i downloaded windows 7 beta and is using that on the original hard drive. Now my brother's computer mother board had crashed and i took his hard drive and put it in the vaio. I wanted to do a clean install of windows xp on that hard drive but its coming up as unknown disk as well. I tried searching far and wide but was unable to find what i was looking for i do not know what the problem is. I also tried taking the original hard drive out and using my brothers but no luck.

Answer:unknown Disk Help plz

Get the OEM setup/diagnostic disk from the hard drive manufacterer and run the diagnostics. Also, check your cables.

I reconnected my external to another port, and that went fine, but this locall disk q remains, and can not be accessed, changed, removed, etc. I scanned for virus's, and all seems ok. How can I remove this, and where did it come from?

Hi Admin,

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

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

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

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

Please Help !! Thank you !!

Answer:WD Passport HD 1 TB disk 1 is unknown

Welcome onboard.

( I am not Admin but still usurp their address to address this query)

Initialise it as an MBR disk. Only more than 2TB drives need to be GPT disks.

I turned on my computer the other day and it decided to run a checkdisk. No problems, everything was fine. HOWEVER, the next time I rebooted, it said that there was a computer software problem and the exact error was "load dlls for kernel", please contact your support person for assistance. Now, every time I boot up, I get this error. It doesn't matter how I boot up, (safe mode, last known good config, normal) I get this error. I saw on the web that the fix action was to run the XP install CD and do a repair, so I tried that; BUT...when I run the CD, it says, "unknown disk" where it normally lists my partitions and it won't let me continue past there. If anyone can please help me, it would be HUGELY appreciated as all of my children's photos since birth are on this hard drive!!! PLEASE HELP!!!

Answer:Please Help - Hard Disk Unknown

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

Hope this helps get you going.

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

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

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

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

Answer:Disk 1 Unknown, Not Initialized

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

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.

my hard drive changed to raw, and now do not look in windows! In the data manager, I can see that it exists. unknown disk no initiated! I can not format it and can not change partition or do anything else? I have tried many programs, mini tools two but it's coming nowhere! is anyone who has any idea how to format or restore it? I have my child's movie, photo and much more on it.Sincerely, Hamidi

Answer:Hard drive to RAW and unknown disk

Welcome to the forum. Raw means its lost the paritionyou need to download specific parition recovery software which will return all the files. If its not showing in disk manager thats worrying does it show correct in the bios?

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

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

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

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

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.

I've had a schlew of problems with a PC starting with a bad installation of Microsoft's Lifecame software leading up to a constantly crashing XP.

I ended up getting a new hard drive thinking that was the problem but at the point of installing XP I get the same problem,

Once XP install starts up and I get to the 'partition screen' I get this as a choice of drives

"Bad hard drive, controller, etc."

So, it can't be the drive as I got the same 'unknown disk' problem with a brand new drive. The power cable and sata cables are fine. If it is a controller - what exactly is that and how can it be fixed?
