An HDD suddenly became unallocated

post #1 of 13
Thread Starter 
Hi all,

While I've copied some files to an old WD 160 GB I got an "driver need to be formatted" error, so I've rebooted.
Now it's gone from My Computer, but I can see it in the Disk management, as an unallocated disk.
How can I convert it back to NTFS without losing data?

PS
I must add that this HDD worked perfectly for a good while now in this rig, all of the sudden it decided to take a break

It's probably Windows not detecting it properly, happens all the time.

Is it a IDE or SATA drive you're using? I'd try re-plugging the hard drive and checking if the cable is damaged.

It's an IDE drive, it was connected via IDE-to-SATA adapter.

I've tried plugging it directly to the IDE cable, yet still the same resulted.

Try restoring the default BIOS settings. Maybe your adapter triggered a change in IDE settings that are still there.

I've tried both loading Fail-Safe and resting the BIOS by removing the battery, but unfortunately no change

BTW, thanks for the quick responds

Just to make sure: is the HDD making any noises it didn't before (constant clicking or something similar)?

If that doesn't work, and using a different IDE port on the motherboard doesn't work either, then the only thing I can recommend is to keep restarting till it comes up again. That might sound dumb to you now, but I'm willing to bet that it's the Windows crappy hardware detection not reading the drive/partition table correctly. I had a very similar problem to yours and it took me 8 reboots yesterday to get an ancient Pentium III rig with a 8GB IDE drive with Windows 2000 on it to boot properly.

Also it would be worth trying to connect the drive to an external caddy, if you have one laying around, but definitely don't consider "converting" or formatting the drive to anything. All the data should still be there, it's Windows that's failing to read it correctly, as this happens all the time when I plug in my external HDDs.

Nop, no weird noise whatsoever from the HDD.

I've got only one IDE port at my MB, so I've tried changing the cable, no help.
I'll try restarting, maybe from a linux live-cd I'll have more luck?

Also, I wonder, should I quick-format the HDD and the try to recover it with a recovery tool?
AFAIK, quick-format doesn't delete the files, just marking the place as available.

I was going to recommend just that. Linux is much more likely to detect it than Windows, definitely give the Live CD a try.

Also you're right about the quick format not deleting files, but you'd have to use an un-delete program to read the stuff off it again. Not worth the risk of reformatting IMHO.

Goto "Disk Management" it's in control panel. Once it loads you should see your disk in there with out a Drive letter

Right click on that disk and click change drive letter. Exit all that and your HDD should be in My Computer

Wasn't able to use the live-cd, anyway, about the Disk management, I can't see the option you've said
