In the old days the heads were not driven back, but for around more than
20 years the heads will park by the momentum of the turns, when there
should be a blackout. IIRC if the drives didn't turn fast enough, the
heads could crash. Today a power outage definitively doesn't cause a
crash and AFAIR even my old 42 MB SCSI survived power outages.
