The Disk II drive icon is displayed so you can tell the Finder when a disk has
been changed.  Normally, the Disk II icon should be displayed all the time,
even when no disk is inserted when the Finder starts up.  However, some Disk
II drives incorrectly report No Device Connected when there's no disk
inserted, instead of the proper I/O Error.  I've seen this on most old Disk II
drives, all the time on the Mitac 5.25" drive I use at work, most of the time
on my DuoDisk at home, but never on the newer Apple 5.25 platinum drives.

If the drive says No Device Connected instead of I/O Error, the Finder assumes
there's no drive there.  An I/O Error says the drive is there, but no disk has
been inserted.
