I just did some experimenting this morning before I came to work; the Jaz
doesn't properly honour the 'Eject' bit in the START STOP UNIT command.
It honours the 'Start' bit, ie. it will spin up/spin down, but doesn't
eject.

(FYI, "scsi -f /dev/rsd04c -s 15 -c "1b 0 0 0 2 0" was what I was
 trying, with variations on the '2' as Start is bit 0, Eject is bit 1)

This was the only medium eject command I could find for direct-access
devices; perhaps the Jaz honours CD-style medium control commands?
