When I rebooted and left the disk 'on' it only would be recognized. Then I tried the other way and rebooted, let the startup programs load, and got a crash. One other time I got a crash also but I'm going to try it one more time (I was fearful to do that). and thanks. I will get back to you. In a message dated 8/11/2012 10:01:51 A.M.

Does the external drive crash your pc once the pc is booted or do u try to boot the pc w/the drive attached? Please try attaching the drive only after the pc is booted & your desktop icons appear. The syntax for the chkdsk command is chkdsk /f /r (that's the forward slash, i.e. the ? unshifted). Since u appear to be familiar w/at least some aspects of the command line, u likely know that, but just a friendly reminder. If the computer shop won't help, or u just don't trust 'em, contact me off list.
