Target disk reporting bad sectors after imaging failing disk

Had a laptop disk that was reporting imminenet failure.  While waiting for a suitable replacement to arrive I tried to transfer an image of the drive onto a portable USB disk.

Unfortunately this didn't work - kept stalling.  In the end I just pulled off as much data as I could and rebuilt the laptop from scratch with the replacement drive.

Problem is...the USB drive I was trying to create an image on is now unusable.  Have tried to reformat in Windows, but stops at 99%.  Also tried to reformat using Acronis and reports bad sectors.

This drive was working fine up until he point that I tried to transfer the failing disk image onto it.

Any ideas what the problem might be?  Can't believe the USB drive has suddenly failed too.

check your warranty - you may have it replaced for free

verify that your USB is not infected by a virus.

I don't think that would be the issue, the disk is completely blank - it won't even mount.

did you check it with an anti-virus application? you should verify that even if it appears blank!

How would a virus get onto a disk that has no logical drives or even partitions on it?

And further, how would an anti-virus program check it?

Can you get to this drive? If yes then run CHKDSK /r on it.

devon-ladAuthor Commented:
No - I can't create a logical drive.  I can see it in Disk Management as unallocated space, but it fails to format.

Ok, then erase it. What is the model of the drive?

WD My Passport Essential USB3.

Have tried the WD drive formatting tool on it - but that failed also.

I guess it could just be a very coincidental hardware fault.

Transferring an image cannot transfer a mechanical bad block. There may be some common mode failure, for example if a power supply sends 8 Volt all over instead of 5 Volt, which will affect everything you connect to the system, but I'd bet on coincidence.

Yes, that's what I thought re. transfer of bad block.  It had been working happily connected to many different machines before the attempted imaging - seems like it could just be another hardware failure.

Not the most expensive bit of kit, so not worth spending alot of time on - but I'll put the question to WD in case they have any bright ideas.

Instead of formatting using WD tool use Erase drive. There are WD tools available that can do this erase.

Downloaded WD Smartware - drive showed up, but the settings tab containing the Drive Erase button was disabled.

Tried a firmware update - still didn't show up.

Tried a quick format using Windows Disk Management - failed, but drive showed as mounted (but unusable)

Now showing in Smartware.  Tried Drive Erase - this failed too.

There are a few diagnostic tests in the Smartware software - will give those a try.

Next step would be - open the enclosure (if the drive is not warranty) and connect the drive as internal directly to motherboard. Then run the diagnostics. This will let you exclude USB controller of the drive as suspect.

Still not found a solution to this even with the help of WD support.

Suspect it's just a hardware fault.

you can still test if it shwos when booted form a knoppix live cd : ftp://ftp.gwdg.de/pub/linux/knoppix/KNOPPIX_V6.7.0CD-2011-08-01-EN.iso   

it uses another oS and driver..
