2TB external HDD

#1 Post by tpch » 15 Nov 2015, 12:35

Hi

I recently had a Samsung Story 2TB external drive fail on me. I've tried testdisk, but think I've gone wrong somewhere and possibly written over something which is now causing the drive to not show up in Windows (it shows in Device Manager under disk drives as HDD USB Device, but doesn't show up in Disk Management or in Test Disk). The drive was initially at least showing in Windows, and therefore scan-able in testdisk.

Can anyone give me any pointers?

Test disk log attached. Thought I'd worked out where the problem was, but then managed to do something which has taken me two steps back so that I can't even see the drive now!

Thanks in advance for any help.

If the disk doesn't show up anymore, it's probably a hardware problem. In this case, you need to contact a data recovery company.

Thanks for replying. That's a shame that it sounds like a hardware problem. The drive was showing up perfectly before in Windows, device manager, and disk management. Now only in device manager.

Anyway, just in case it sheds any more light, here is the testdisk log (which I thought I'd attavched)
