When you have a situation where the BIOS can't detect (for sure) if
the media has been changed or not.  For instance, if you have a
write-protected disk in the drive, and the drive has been idle for
over a second or so, the state changes to "Maybe".

You can still yank out a non-write-protected disk and put it back in
the drive.  So the "Maybe" state really reflects the fact that the
BIOS hasn't had a chance to match disk serial numbers yet.
