EXT :Re: CD Burner Auditing

[Boyce, Kevin P. (AS)]

Hmm.  That is an interesting thought, but I would think there is no 
filesystem that would be able to be mounted until the user has written 
something to the disc first. In other words I don't believe blank media 
gets mounted as part of the burning process (at least not in my 
experience anyways--maybe I'd need to turn some feature on for that?).
