"Maybe" means that the disk was ejected, but the same disk might have
been put back in the drive.  When the drive is in this state, the next
access will cause the BIOS to check the serial number against the last
disk that was there: if they match, then the media hasn't really
changed, and the operation succeeds.  If they don't match, that
operation returns the "media changed" error.
