	  Most of the full-height hard drives will automatically park
	the heads on a landing zone.  This is true of Quantum, Micropolis
	and Seagate.  These drives shutdown the read/write circuits as soon
	as power is lost and in the case of the Quantum, if power drops
	below a certain level it will shut off the read/write circuit and
	perform a recalibration of the head assembly.  So I don't see any
	benefit to parking the heads of these drives.
	  On half-height hard drives, it is a good idea.  I do not know of
	any half-heights that automatically park the heads for you.
