I used Killdisk to wipe a hard drive intending to clean it before selling.

I now cannot use the hard drive. Device Manager in Windows reports the "device is working properly"

It is connected using USB.

I have tried:

  • Using Disk Management in Windows, can't operate on drive
  • Using GPartEd, cannot see drive
  • Various other software with same result
  • Using two other computers
  • Using both the USB and eSATA connections

The drive (or maybe the record represents the bridge, not the drive itself) does show up under Windows in "My Computer" as a "Removable Disk".

  • Opening it results in "Please insert a disk into Removable Disk (G:)."
  • Attempting to format results in "There is no disk in drive G:. Insert a disk, and then try again."

Any ideas?

Does it happen to have a security lock code on it? (There's a "secure erase" command or something in the ATA standard... it might have used that option, although I'm not sure it has.) – Mehrdad May 19 '11 at 1:25
Mehrdad, it is a standard hard drive in a standard enclosure. No security locks. – James May 19 '11 at 5:04
@James: Sorry, I meant a software lock, nothing to do with the enclosure. – Mehrdad May 19 '11 at 5:07
Oh, sorry, no, nothing of the kind. The drive "contents" are 100% unallocated space. – James May 19 '11 at 5:09
@James Huh interesting, okay. – Mehrdad May 19 '11 at 5:13

Try using a newer computer to set up your partitions on it -- some older BIOSes seem to prevent this from working.

Randolf, what does the BIOS have to do with it? The hard drive is recognised on both computers, and they are both under 4 years old. – James May 19 '11 at 5:03
@James: I'm not sure exactly what the BIOS has to do with it, but I suspect the BIOS because upgrading it in at least one instance resolved the problem for me for initializing and partitioning external USB mass storage devices. – Randolf Richardson May 20 '11 at 17:01
