[clue-tech] Detecting media change

[David L. Willson]

Anyone have a "best" way to detect the successful swap of a USB disc (or new blank
optical media)?

I want my backup program to automatically detect the attachment of new media, validate a
few things, and then blank that media.  Hmmm...  I was thinking of doing something fancy
like reading the UUID off the filesystem and keeping track of that locally, but I guess
I could do something simpler, like recording a "last-used" bookmark on the currently
attached disc, and deciding what to do with the currently attached media based on
whether that bookmark is present and what it's mod-date is.

Hmmm...  Thoughts?
