Yes, I believe it may be possible to run `chkdsk` on a USB drive. I have only followed the information stated in the `chkdsk` manual, here  (www.microsoft.com). Do try the following (from Windows XP, not the XP CD): `chkdsk drive_letter /r /x`
  The `chkdsk` manual warns that this may take a long time. Quote: "If you use chkdsk /f on a very large disk (for example, 70 gigabytes) or a disk with a very large number of files (for example, millions of files), chkdsk might take a long time (for example, over several days) to complete. The computer is not available during this time because chkdsk does not relinquish control until it is finished."
  I think this is likely the worst-case scenario, but I am not sure. It sounds like a good warning for people using 80GB drives with a Pentium II. It should be much faster on modern systems, but should still take a pretty long time. The real killer is the 'bad block checking' feature. Checking for bad blocks on an ext3 filesystem in Linux takes very, very long as well.
