If an RA81 has been spun down due to a power loss or a dismount when
/NOUNLOAD has not been set, the drive will stay spun down until a MOUNT 
request has been issued for the drive or the RUN/STOP button is toggled.

During system startup, the drives do not all come bouncing to life at the
same time because the sequencing cables allow one disk to fully spin-up
before another tries to.  This protects the power distribution panel from
an accessive current draw.
