Computer Management fails to show disk usage

Q: Computer Management fails to show disk usage

I have five Sata drives. Of these five, Windows 7 Pro 64 "Computer management" reports that two of them still are 100% free despite both having significant usage as reported in "Computer" and "Explorer"

F: Simple, Basic, NTFS, Healthy, Primary partition,

"Computer management" Capacity 92.21GB Free 92.21GB
"Computer" Capacity 92.2 GB Free 16.8GB

L: Simple, Basic, NTFS, Healthy, Primary partition,

"Computer management" Capacity 389.59GB Free 389.59GB
"Computer" Capacity 389GB Free 379GB

The L: drive is newly installed and only ebook files are on it. What might have caused this and can it be corrected?

Preferred Solution: Computer Management fails to show disk usage

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

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

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

A:Mystery Partition In My Computer Doesn ' t Show Up In Disk Management

Hello rawmess and welcome to Seven Forums.

My usual disclaimer: I'm not an expert at anything.

According to your second screenshot, Disk 0 is 596.17GB. That should be the total amount of space on the disk. I'm guessing that HP installed a "620GB" hard drive. That would be based on the manufacturer using a decimal rating system where 1000KB = 1MB and 1000MB = 1GB. But in computer speak (or the binary system that computers use) it actually takes 1024KB to equal 1MB and 1024MB to equal 1GB. So if you keep dividing 620GB (620,000,000,000 bytes) by 1024 (you have to divide 3 times) you will eventually get around 596GB.

As to the mystery Q: drive, since it doesn't show up in Disk Management I'm thinking that perhaps it was a removable drive (external hard drive, flash drive) and the previous owner gave it the letter Q. Here's a couple of previous Forum threads that may offer some help.


Mystery Drive (Q:)

Hope some of this helps.

A newbie here that just completed a first-time new Win7 PC build. Successful installation of Win7 Pro on WD 600GB 10000 system drive. Went back and installed 4 additional HDD. (2) WD Caviar Black 1TB 7200 RPM and (2) WD Caviar 7200 500GB HDD from XP system that were used for storage.

BIOS sees all HDDs, but are not viewable in Disk Management.

System Specs:
Antec Nine Hundred
Intel Core i7-980 3.33ghz
24GB (3 x 4gb) Corsair XMS3 1600mhz RAM
PNY Quadro 4000 2GB VC
Corsair 850TX 850W PSU
1 WD 600GB SATA HDD for OS
2X WD 500gb SATA HDs (previously used on WinXP system for storage)
1 Pioneer Blue Ray Burner SATA BDR

SATA4=WD 500GB (previously used as storage on XP system)
SATA5= Pioneer BDR
SATA6= WD 500GB (previously used as storage on XP system)

SATA configuration is enhanced. BIOS is 0701. Marvel 9128 Controller [IDE Mode] PCI/PnP is set to [NO] which was the default setting. The grey SATA1-6G headers are not in use.

Device Manager lists all drives.
However, only three are visible in Disk Management. Missing (1) WD 500GB (previously used on WinXP system) and (1) new WD 1T.

What am I missing here?

Thanks in advance.

It needs to by GPT to see all 3 TB.

How did you do this switching back and forth from MBR to GPT??

Stay away from dynamic disks at all costs. Just say no if they are ever offered.

What is this disk's purpose? Data only? OS? Data and OS?

Do you want just a single partition on it?

Hi All,

I would really appreciate some expert advise on this issue I have, I am running Windows 8.1 Professional. (and no thats not the issue )

I have just bought myself a new Seagate 5TB internal drive, model is a ST5000DM000. I managed to put the drive as an external and formatted the drive with disk management and also converted the disk to a GPT so it is just one partition as 5TB, the drive will work perfectly fine as an external in a case.

But, if I plug the drive as an internal via SATA cable as a second disk, my bios identifies the drive. Afterwards when Windows tries to boot it takes an additional 3-4 minutes to boot, eventually I log on and the disk is not present nor is it shown in disk management or device manager.

I have tried using different SATA ports on my board (nearly all of them including one that is coloured different which I thought would be my savoir), I am yet to try run it as a secondary drive in another machine which I hope to do in the coming week to see if I can replicate the issue.

Any feedback to this would be sincerely appreciated.

Many thanks

Any ideas why this would be happening?

A:Disk Management will not show any volumes

I came across a thread where they suggested checking the Windows/System32 folder for a file named dmserver.dll.

The file had been renamed to "dmserverxxx.dll", and when renamed to "dmserver.dll" it fixed the issue.

Apparently happens sometimes when new externals are connected.

Worth checking.

My machine O/S is Windows XP SP3 with all current updates.

A few months ago I had a problem with my boot Hard Drive (blue scree and error code indicated lost boot sector). I installed a new hard drive and rebuilt my system .

I have some files that were not backed up on the HD and would like to try to recover some of these files .
The HD is Samsung SP4002H 40GB IDE Drive. I have put the HD in an external Drive enclosure (Sabrent ECS-STU35) and connected it to my PC via USB. When I turn on the drive enclosure:

Device Manger shows a SAMSUNG SP4002H USB Device entry under Disk Drives; and
a USB Mass Storage Device entry is under Universal Serial Bus Controllers.
The HD from the Drive enclosure does not appear in My Computer or in Windows Explorer.
The HD from the Drive enclosure does not appear under Disk Managment.
Under Disk Management I do see 2 Hard drives (Disk 0 is a 500GB and Disk 1 is 120 GB) - the 40GB drive is not present.
I suspect that my original problem with the 40 GB HD was a damaged boot sector and partion table.

I am looking for ideas on how to make the drive visible to to Windows XP and also some thoughts on how to partition table and files.

Thanks for your help

A:Hard Drive Not Show in WIN XP Disk Management

how about putting it into slave and then you can use it to recover all files that have not been corrupted by the bad sectors. you can also get your HDD tables by formatting it when it's slave...

although its not clear why you didnt bother replacing the damaged boot file with the install disc, its only one or two files...and if your lazy like me put the install disc in and do a recovery install, it looks like a normal install but it replaces all the original files like bootloader and other things that i cant think of right now...

I have been trying to find an answer for hours on google and am throwing in the towel.

I have: HP Desktop xt963, Windows xp sp3, 1.2 ghz processor, 512 RAM, 2 internal WD 40gb HD (one ide and one sata), 1 external Hitachi HD (the problem). The external HD is connected to the system via a generic ide/sata cable adapter.

The external HD is first connected to power, the power turned on, the adapter cable plugged into the HD then plugged into a USB 2.0 recepticle on the computer. (The USB 2.0 was an add-on. The existing USB 1.0 was factory installed.)

At that point, a "new hardware" message appears preceded by the usual chiming sound. An icon saying "safely remove hardware" appears. In Device Manager, the HD is recognized and in Properties it says "device is working." However, the HD is not recognized in My Computer or in Device Management.and accordingly is useless to me

In the beginning, it did work off and on for a while, but lately I can't use it at all.

I have tried "uninstalling" in Device Manager and restarting the computer. Upon restart, the device shows up again in Device Manager (installed) but nothing else changes. I tried connecting via the original USB 1 but it didn't make any difference.

I connected the cable and HD to my wife's Dell laptop (Windows xp) via a USB 1.0 port and viola everything worked just fine.

It would seem (a) there's nothing wrong with the HD or cable adapter or power supply, (b) t... Read more

A:External HD Doesn't Show in Disk Management

I just discovered something. After you utilize "safely remove hardware" before disconnecting the HD, the next time you connect it it does not power up (the power light is on but you can't feel the disk spinning) until you hook up to the usb port).

Previously, I had not been using "safely remove hardware" at all so I'm guessing the disk was running when conneting to the usb and that's when it didn't work right. But when power is not running when you plug the cable into usb (and it wasn't just a moment ago) then eveything is normal (as it is right now).

At least I'm going to go on that assumption until proven wrong and you can consider this thread solved.

I purchased a 500 GB drive about a year and a half ago to hold my backups for my main 160 GB drive. Just about everytime I have to reboot my PC, the 500 GB does not show in Computer. I them boot again and it shows and everything is fine. I have attempted to sort this out but no luck yet. Today I had to reboot and the 500 GB did not show. I have rebooted about four times but nothing. I went into the Bios and did not see anything strange. The 500 shows up as it should. The only unusual thing I see in the setup is that my main drive with the C and D partitions is listed as drive 1 while the 500 GB with my backups is listed as drive 0. I believe the reverse is the preferred but don't know if it really matters. Here is my Disk Management and a prompt that says I must initialize it. The two partitions on the 500 GB are primary if that makes a difference and the prompt refers to Logical. Any help is appreciated as to why the 500 GB is not showing. Thanks, == I just found out how to initialize the disk, but it looks like I will lose my backups. Not a big deal, but I want this to not occur again. Does it sound like a bad disk that might be causing this?

A:Hard Drive Doesn't Show in Disk Management

Normally, one would expect to see the Windows drive on Sata 0, but I don't think it really matters that it's not.

Initializing the drive means it's asking for it to be partitioned and formatted, but the puzzling thing is why did it lose its partition in the first place?

Was the partition on Drive 0 a logical partition?

I'm off to do some investigating.

A:My Hard Drives Dont Show Up In Disk Management

That doesn't make any sense, can you post a screen shot?

Read other 5 answers

As a preamble, everything is working fine, and the volume/partition in question is unimportant so it's ok if I lose the data (I'm gonna format it anyway). No external drives are connected, so only the HDD and the internal DVD drive (no disk in it) are in play.

On my 1TB internal HDD, Disk Management and diskpart disagree about a volume and/or partition (I'm not sure if it is "actually" both a volume and a partition or just a partition). DM identifies (in the list of volumes) a 181GB Healthy Primary Partition. diskpart does not see this "volume" at all, but it does see it at as a partition. Twice. One is 181GB logical, one is 189GB extended, neither is primary.

Here is a screenshot of DM showing 5 volumes. In the order shown they are: Windows reserved, MS Office Click to Run (I think?), OEM recovery, the "mystery volume or partition" (red dot), and Windows C:\.

Here is what diskpart has to say about it:

DISKPART> list partition

Partition ### Type Size Offset
------------- ---------------- ------- -------
Partition 1 Primary 100 MB 1024 KB
Partition 2 Primary 719 GB 101 MB
Partition 0 Extended 189 GB 719 GB
Partition 5 Logical 181 GB 719 GB
Partition 4 Logical 8137 MB 900 GB
Partition 3 Recovery 22 GB 908 GB

DISKPART> select partition 0

Partition 0 is now the selected partition.

I did not even know of such things a few days ago, but in diagnosing an issue I was having, I discovered that all of our external hard-drives, regardless of which of our computers they may be connected to, show as Active in disk management.
All of our ext. drives are identical 1-TB Transcend; one is brand-new and we have had the others for a couple years.
If I ever did anything to these hard-drives that would make them show as active, I have no idea what it may have been; they have probably been like that for a long time.
The only reason I even found it out was that I had to look in Disk Management.
Has anyone else had their external hard-drive to show as Active ?
Is this just a weird thing with Transcend drives ?

I tried installing VMWare workstation and when it got to then end it said it could not create the user and group name on my system.

When I went into Computer Management and clicked on Local User and Groups, in the Groups folder none of the built in group names show up.

For instance in Groups you should have:
Backup Operators
Network Configuration
Power Users (etc.)

Well you get the jist of it.

Anyways none of those entries show up. I tried adding in Administrators manually and it said user group is already there. It doesn't show though.

I also created an entry called TEST and I added me to that as an administrator and it created it however then TEST name doesn't show up
in the Group Names.

At one time I had some malware and when I finally got rid of it I used a registry cleaner to clean up my registry. I was careful not to
delete stuff that should be there but I was wondering if something could've been deleted. Maybe a SID entry? I compared my desktop registry
with my laptop registry and the SID's do seem to match up for the most part.

I googled this problem and a the MIcrosoft website said to reinstall SP3. I did that but still no luck.

Does anyone know what to do? I am running Windows XP Pro SP3. I have a Workgroup set up but I'm not part of a domain if anyone asks that question.

Any help would be appreciated.



A:No Built-in Group Names Show Up in Computer Management

It sounds most likely that there's something corrupted in your registry that's related to permissions - and I'd suspect that it's related to the malware rather than the registry cleaner. I'd suggest something like the RRT (Remove Restrictions Tool) as a first guess, but haven't used it myself. It's available here: http://www.sergiwa.com/en/modules/mydownlo...cid=2&lid=1

What can I do to make it better? Please help me.

A:External hard disk not detected in My Computer and in Disk Management

First off, how old is your Toshiba external HDD? Also, when it starts to spin up, do you hear any sort of clicking or whining noise?

If you hear any noises that sound off, it's possible your external HDD is failing.

When you formatted it, what file system did you use to do so? Because sometimes even if Windows can't detect it, I have had success with booting with a Ubuntu Live CD, and then connecting the external HDD in order to format it that way. It all has to do with how Windows formats HDD's and how Ubuntu and other Linux systems do.

If you can I recommend downloading Ubuntu onto a CD and boot to it on one of your computers, in the Live CD mode, so it doesn't install anything. Once its loaded, plug in the Toshiba and try to format it as NTFS (this is important, because Ubuntu doesn't use it as a native file system, so you need to make sure that NTFS is selected on the format window, not EXT4 or the other types of Linux OS File Systems)

If it doesn't work, post back here, and I will see if I can help you some more. Also feel free to PM me if you have any other issues.

(what my recovery partition contains, am I missing a file?)

I copied the recovery partition over to another block of unallocated space since it was in the way of a partition I wanted to merge with my Windows partition.

After doing that, Disk Management displayed "Primary Partition" instead of "Recovery Partition".

How do I get it to show "Recovery Partition"? I re-registered WindowsRE using reagentc /setreimage, I even obtained new files for WinRE from the install.wim in my ESD folder, used 450 MB on the dot, and I tried this diskpart script:

rem == HideRecoveryPartitions-UEFI.txt
select disk 0
select partition 3
set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
gpt attributes=0x8000000000000001

It still displays "Primary Partition". All I want is for Disk Management to identify the partition as the Recovery Partition.

Also, what is the default PBRImage Location (the one that uses install.wim, not winre.wim) for Windows 10? I'm currently using a custom one, but I'm curious of the default one.

A:How do I show "(Recovery Partition)" in Disk Management?

So despite my computer being able to boot into a UEFI-environment, I had to use a BIOS-environment script to get the desired result.

rem == HideRecoveryPartitions-BIOS.txt
select disk 0
select partition 3
set id=27
list volume

This topic can now be locked (although I am still curious about the default PBRImage location, as mentioned previously--so if anyone knows that, please post :3).

Hi all,
I had a problem of Windows 7 x64 Pro not seeing my 8TB Seagate USB HDD no matter what I tried, it just would not show anywhere except in "Devices and printers" and there was nothing I could do with it there!
After several weeks and hours spent on the net searching for an answer I struck the resolution by chance, because i like to fiddle about my operating system.
In case someone is still facing such a problem of external USB HDDs not being recognized and not even showing in "My Computer" or in "Disk Management" (as I had), here is what I did to resolve this problem:
1. Open "Device Manager>Universal Serial Bus Controllers",
2. Look for the USB "Mass Storage Device" and uninstall it by selecting it and hitting the "Uninstall" menu button at the top (with the red X on it),
3. Do a "Scan for hardware changes", the system will find and install the appropriate drivers and you should be able to find and use your device now.
I hope this will be of help to someone.

Hello guys!

This is the first time I am asking for tech support,which is to say how much of an ordeal I am in!

I have an external hard disk,and the last time I used it,I unplugged it without going through the 'Safely Remove Hardware' process.Consequently my Hard Drive was corrupted.I used all sorts of programs to format the hard disk,and finally I was able to get the device back again.Here is what I did: I deleted the volume on the hard disk and then initialized it on Disk Manager,and then,formatted it on MiniTool Partition Wizard.It was fine again.

However given that I also use my PS3 as a BluRay player,I tried to convert it into Fat32.The program I used to do so was ultra slow and in the end,I had no choice but to disconnect my Hard Disk.As a result,I was back to square one.This time,things are worse.

Whenever I connect the device,''Computer'' won't show anything and ''Disk Manager'' will freeze! I've formatted the Hard Disk on the Partition Wizard and according to the latter,there is nothing wrong with my hard disk - there is not any way to verify whether this is true or not.I can also see my Hard Disk on Device Manager.

Can you help me plz?? I don't have enough money to buy another external hard disk.....

None of my usb drives are showing in My Computer. None of my drives are showing in Disk Management at all! (not even my internal hard drives)
I've tried my external HD, Flash drive, ipod, & my digital camera. Windows plays the normal sound when I connect them but nothing happens. None show up in my computer. The ipod charges as normal and I can print via usb.

The only things listed in My Computer are my 2 internal HDs C: & D: and my DVD drive H:

I have been having issues with my external hard drive. It is a Toshiba STOR.E PARTNER 2.5" 1TB. I understand there are many threads relating to similar problems but I thought it would be best to post my exact problem because none of the solutions I have read worked for me.

The problem began after I accidentally disconnected the hard drive whilst moving my laptop. I assume something important must have been happening at the time of disconnecting. The HDD still appears to work in the sense that the light is on when connected and my laptop makes an acknowledgment sound when I plug it in. This is almost certainly a software/driver issue.

So when I plug it in, it does not appear in My Computer at all. When I go to Disk Management there is also no sign of it existing. It does seem to appear in Device Manager under 'USB Mass Storage Device' but it has a yellow ! mark on it. It has the Device status: This device cannot start. (Code 10). I have tried upgrading drivers but they seem to be up to date. I have also tried uninstalling the drivers and restarting the laptop - it attempts to reinstall them but fails to do so.

I have also tried using all of the available USB ports on the latop but all have the same outcome as above.

Any help is greatly appreciated as I have important files that I need to use on this HDD. I have two images attached below:

Device Manager:

Disk Management:

Hi all,

I'm having a problem with a 3TB Western Digital Red drive.

It does not show up in My Computer, Disk Management or Device Manager or diskpart >> list volume.
Also a no show in the Western Digital Data LifeGuard Diagnostics tool and CrystalDiskInfo.

It does show up in BIOS (See screenshot) and also in the Intel Rapid Storage Technology tool (See screenshot)
In both places it is showing as 0GB though.

What I've tried:
Unplugged all other drives except the C Drive and the 3TB WD, same result as above.
Unplugged all other drives except the 3TB WD and launched the installation CD for both Windows 7 and XP to see if either would recognise it. Neither did.

I'm out of ideas (I did see a few things online I didn't try, like uninstall the IDE ATA/ATAPI controllers from the Device Manager, since I don't really know what that means I didn't)

DVD/CD drive is not listed on "Computer" nor on "Disk Management"

Windows "Trouble shooting" reports "TSSTcorp CDDVDW TS-L633J" is missing (or corrupted ?)

With a DVD movie in the drive, the drive spins up but does not auto play. It just spins down and stops. The drive is not listed in VLC.

Four days ago I uninstalled (using RevoUninstaller) some ancient apps I never use with a restore point before each uninstall. 4-Feb, 5-Feb
1. CloneDVD2.exe
2. AnyDVD.exe ... this one was a ring in (unsolicited)
- both by SlySoft.com ... there is an obvious omen in there ...

I have tried 3 system restores, one each before the unstalls and one a daily (1-Feb) system restore. Each System Restore failed.

On the third "fail" (1-Feb) I decided to try Windows Troubleshooter, targeting devices and hardware

After the attempted fix ...

I am way in over my head, this is the first system Restore I have done in 25 years.

For the past 12 months I have been reading up on virual drives, imaging, OEM backup, recue discs etc ... all a bit late for todays dilema.
I have never made a media disc of the OEM -- could I do that onto a USB stick (or USB pocket drive) or must it be a CD/DVD ?
recently I made a "Rescue Disc" for my new unused Lenovo ... so I am learning

How would I know if it is a hardware or a driver problem ?

Would appreciate some help, thank you

A:DVD/CD drive not showing on Computer nor Disk Management

Any easy hardware check: Try booting from bootable CD/DVD. Boot from CD/DVD is handled by BIOS (and before Windows even starts running). So if it boots from media OK, it's a windows issue

To check Windows, download and run Filter Load Order Tool. Is the DVD drive listed in the display? If so, select it then hit the Clipboard button in the display. Paste the results into next post

Hello everybody,
Just got a Samsung Chronos 7. It came with 4 partitions...or at least that's what it seemed to me. I had the usual 100Mb System one along with the OEM 23,78GB. I wanted to change the Windows version so I boldly booted from the Windows 7 disk I was interested in. At one point, the system asked me where I wanted to install it. I left the two afore mentioned partitions alone, just in case.
I know I should whip myself for not doing any back-up thinking that by leaving those partitions alone, I could fall back on my feet if anything went wrong.
The fact is that I did reinstall Windows all right but lost all my drivers and basically all the programs that came with this laptop. I don't know if they were worth anything
Now my confusion is that I can still see the two partitions when I go to "computer management". But they don't appear in the Computer window. How is it so? Do you think there is a way to "reach" the OEM partition and restore the system? Or does it work with the dedicated Samsung recovery system that I simply and stupidly squashed?
Many thanks in advance for your kind help!

A:External hard drive not seen in disk management and computer

USB drives dont show in BIOS.

The USB adaptor may be USB 2 and your USB may be usb1 and as such is having trouble seeing the drive.

Or your USB sockets or drivers are faulty, try another USB device in them

Skill level: Beginner

I've been toying with the idea of swapping the hard drive out of my Acer Aspire 5740-5780 laptop with an Intel SSD 330 to improve performance. So I used Norton Ghost 15.0 to copy my data to my new Intel SSD. So after that was done I swapped hard drives, and booted up. My laptop was stuck at the Acer Splash Screen (F2 and F12) menu. I'm able to press either key, but it locks after that.

Then I read somewhere that I need to go through sysprep. So I swapped the original hard drive back in. After attempting sysprep, I get an error, Fatal Error...

Now as I'm typing I'm using my original Hard Drive just fine on my laptop. However, when I connect my Intel SSD via USB on my external enclosure - it is no longer detected in My Computer or Disk Management.

A:SSD no longer appears in Disk Management, or My Computer, no Activity

Have you tried restarting the computer with the SSD connected? Also, a clean install is recommended, although cloning the hard drive can be done, but much easier with Paragon migrate ( not free $19.95). it will transfer the complete OS and align the SSD at the same time. You may find this useful, SSD - Install and Transfer the Operating System

My computer is not automatically assigning a drive letter (path) for a new external hard drive device. (Manhattan Quantum Bigfoot USB device) Hoping to manually assign a letter I try to go into the Disk Management folder and manually do it. However each time I attempt to open the folder it crashes (resets) my computer. If the device is NOT hooked into the USB port the folder will then open with no problem. It only crashes when the USB device is connected. FYI: the hardware device page indicates that the device is working properly. It just has not been assigned a drive letter or path.

My OS is Windows 2000 Pro.

Thank you for any suggestions you might have.


A:Opening Disk Management folder causes computer crash

I would be willing to bet it is a driver problem as that drive is pretty old and as far as I could tell the only drivers available are for win 98.

SO basically, i'm doomed.

when i plug the damn thing in, SOMETIMES windows will say that it is "not recognized", and SOMETIMES Windows won't say nuthin at all. jsyk i've tried 5 times, and only one time windows responded with that uplifting message.

i tried searching for the device in my computer, not there. there is no "removable disk" icon either.

i also tried going into disk management, not there either.

oh and i've also tried this on 2 other computers.

SO therefore I assume that the thing is un-salvageable. UNLESS of course one of you angels reveal that it is not actually a goner, and that i can actually still access it and save my life. in which case it would just mean i'm a complete tech noob. however, that optimistic situation seems highly unlikely, and therefore i shall return to my assumption that i am doomed.

seeing as life is so, is there any way i can recover my data from the thumbdrive? and no, i can't send it back to the dealer because i never actually bought the thing; it was given as a door gift at someone's birthday. IKR.

so yeah.

hi i am new to this and 18 about to go to uni next week so i need some help and FAST! i bought a 320gb hardrive in june 2010 and it was perfect i made a back up of my whole HP system. However a friend of mine plugged my hardrive into her apple mac and i think my hardrive must have synced to her hardrive called time machine or something like that and now i am trying to use my hardrive in my hp laptop it wont work.

ive tried everything it wont show my computer i searched for help all over the net and with technicians on the phone saying to go into disk management and its not there either. One techinician was sayin i might have to reformat it on the mac.

this cost soo much money and i cant afford to buy another one nor can i afford to lose all my data on this one..

please is there a genius out there that can help me!!!!!!!!!!!

A:Hard drive not recogized in my computer or disk management

Timemachine shouldn't automatically synchronise to the hard drive, unless told to do so. Also, in order for time machine to function on that drive, it requires it to be formatted in the MacOSX native filesystem.

In case your not aware, Timemachine is Apple's backup software, designed to backup Apple systems.

If the data on the hard disk is not of any consequence (e.g. it contains no essential data), it can be formatted as NTFS, which will then be read by Windows. Unless it has been formatted as a Mac OSX partition it should be read natively anyway. In other words, it should be NTFS still.

Lets go back to basics:

1. If it's an internal hard drive, does BIOS identify the hard disk?
2. Your positive disk management doesn't identify the hard disk?

You could use a bootable partition editor like GpartED to boot from the DVD drive and inspect all your connected partitions.

You could also boot from a Linux Live distribution like Ubuntu as well, which would enable you to check your connected partitions/drives.

The fact Windows is refusing to identify that hard disk is leading me to suspect its been re-formatted as a Mac OSX filesystem and as such can't be read from Windows. If its been re-formatted your data is already lost, in which case just formatting it will resolve your problem.

I have a Western Digital (WD) 250gb external hard drive and run Windows XP on my Asus Eeepc laptop.

One day I pulled my external hard drive straight out of my computer (didn't use "safely remove hardware"). From now on it isnt displayed in my computer, and it doesnt appear in disk management either. When I open device manager and then open my WD SES Device, it tells me the device is working properly. I have tried updating the driver and uninstalling it, but everytime I plug it in reinstalls itself and tells me it is working fine.

I am not a computer guy. I have read other forums and none have a solution for me. Does anybody know how to access my external hard drive? (please write responses in simple language with simple steps I can follow)

I've been having this problem for a few months now. I recently built my own computer, having been on a lap top for a couple of years, and found my old external hard drive. I plugged it in to the new computer, and it said something about needing to be formatted, which I promptly did due to nothing of importance being on it. I went to sleep, and woke up to see that it couldn't be formatted.

This is where my issue begins. It no longer appears in Computer, or Disk Management. Disk Management won't even load if I have the drive plugged in. There seems to be no way at all to format the drive, since Computer, and Disk Management both don't load when the drive is plugged in. Any help?
