Here's a related question:  How can I grab control of a specific disk drive?
What I want to do is I want to write raw data to the disk drive (like Apple
Diskmaker does), but I have to make sure that the system doesn't eject the
disk I have in there, put up a disk switch alert, and have an unsuspecting user
put in a disk only for my program (once it gets control) to write all over
their disk.  Also, it would be nice if I could ask the user to switch disks--
if I want to unpack a compressed disk image from a disk to a different disk in
the same drive, for instance.

(Right now what I do is never call Get/Wait NextEvent, don't use any resources
in the critical section, and don't allow single-drive use)

Also, is there any way I can get a descriptive name for a specific floppy drive
(for instance 1: Bottom drive 2: Top drive 3: External drive, but without 
hard-coding that).
