:P~When it does, the disk starts yanking the signals on the SCSI bus

Actually, what I've noticed is that the drive will just spin down
and will then start up and spin down erratically.

:P~According to the little booklet that comes with the drives, you need
:P~something like 50 cubic feet per minute of airflow directly across
:P~the drive.  I'd get a couple fans and blow air across all the drives.

The newer 'cudas seem to be better than the older ones in terms
of not converting energy to heat, <g> but they still require a
fair amount of airflow over them.
