Hi!

I have WD Passport Essential (750GB). Overnight, my files just dissappeared and only the RECYCLER folder is visible. Going into properties, it shows that disk space is used, so I think i can be sure that my files are still there.
I try to read the HD in ubuntu, but my PC hangs. Seems there's trouble reading from the HD.
Checked for viruses using K7 antivirus, and its clean.
I'm trying to recover my data using free tools, but haven't really found a good one. But, I don't know if thats the best option too.

Any suggestions?

Thanx all!

Hi,

I just tried running chkdsk, and it hangs!! Program closes as soon as the HD is unplugged!

Thanx

Thanks for posting the link: It's all interesting stuff.

Are you able/willing to remove the hard drive from the enclosure and connect it directly to the motherboard of a desktop PC? That would eliminate any possibility of a problem with the enclosure USB-SATA adapter, and data corruption during transfer over a USB connection, and would be a preferable option.

Edit: Are you aware that you will end up with a 750 GB image file if you intend to copy the whole hard drive?

Hi,

I'd rather not, I feel. I've lost a Transcend HD while doing that.. ended up with a void warranty :/

Thanks!

Have you considered running badblocks from the Live Ubuntu CD to see where and how extensive the problem is on the hard drive?

Have you considered using TestDisk run from a Live Linux CD (instead of Windows) to attempt recovery of your files?

Open a Terminal in Ubuntu and enter:

sudo fdisk -lu

and press <ENTER>, to determine the designation of your external USB hard drive.
(It will be something like sdb, sdc, sdd. Your internal hard drive will be sda.)

In the Terminal type

sudo badblocks -sv /dev/sdd
(assuming your external hard drive is represented by sdd)
and press <ENTER>.

You will end up with a list of bad blocks with their locations. Record the locations.

I have WD Passport Essential (750GB).

The logical first step would be to attempt to use the Western Digital diagnostic utility to test the hard drive. I don't know whether the DOS (bootable CD) version can be used on a USB connected hard drive, and you might end up having to use the Windows version of the utility. (The Windows version is installed in Windows as any normal program.)

Run the Short/Quick test first and then the Long/Extended test. There is a chance that the utility will offer to repair the problem during the Long test. If your files are important, I suggest that you decline the offer and attempt recovery of the files first, before trying the repair.
