I just saw a comment from Marco in the spam blocker (he sent html email)
which notes:

1) That /cygdrive should be avoided in the tar command.

He's right.  --one-file-system should be added to the tar file creation that
should avoid trying to recurse into /cygdrive, /proc, or /dev.

2) That the USB drive should be formatted as NTFS.

That shouldn't be necessary if you're just using tar and it is another
reason for using tar rather than copying files directory.

FYI.
