I think it needs some kind of temporary disable option, possibly on a per 
drive basis.

The burning library I'm working on won't use a device if it's mounted, 
so if a user inserts a CDRW with a valid filesystem on it, they won't be 
able to blank it or burn to it until they unmount it.
(insert, unmount, burn.. seems counterintuitive, and I think I'll end up 
fielding thousands of "can't blank CDRW" bug reports :)

Same problem with backing up a disc.  if it's inserted while my program is 
running, it's probably a safe assumption the user doesn't want it 

How do you do the automounting with CDs?  some CDROM drives take a few 
seconds to figure out they're empty if you're just polling with mount.  It 
might not be a good idea to manage all cdrom drives in all cases.

If it's polling, then a far more interesting failure mode is a race
between mount and erase on a CDRW.  app opens device, locks drive door,
gives a 5 second warning that all contents will be lost.  automounter
kicks in, mounts the volume, runs an auto run script.  app sends the blank
disc command...
