This is just the way it should be. If you send a SHIP command to a Quantum
drive, it will spin down and just sit there waiting for some reviving command
from the computer. If you look at some SCSI specs, this is perfectly OK:
The SHIP command really is called "START/STOP UNIT" in SCSI terms, so
that's what Quantum drives do.
