>Well, sure. Except that I DO have a purpose. A training session is being run with my app, which I want to be fully functional only if the user has the right token - in this case, a floppy diskette. The volume serial number is the only diskette property not copied by DISKCOPY, which makes it difficult to make more than 1 token diskette for the training class.

PMFJI--Just an idea from left field, but could you write a custom copy routine that branded the disk with its own serial number? Then you could make sure that they matched.
