HD trouble

[califas]

I sold my old HD off my T23 on ebay and the buyer says its DOA. It was working the day I sent it off and I packed it up well. The only thing I can figure is that I was using it in an external enclosure and had it assigned as drive letter k:

Would the drive formatted as k: cause it not to boot up? If so whats the easiest way to re partition it and format it to c:

TIA

I don't think that merely reassigning the drive letter in Windows would cause the drive not to work.
