Summary: I'll ammend what I said.


Hi,

	I think I shoudl ammend what I said about  parking the
heads on a Seagate drive.  From what I observe, it seems that when
operated with an adaptec controller that the drive parks itself at
power off.  I can't say if the Z-8 MPU or whatever is in the drive
itself does this, or if it is related to the controller card.  It
may or may not work with a WD controller.

Berger@clio alluded to the above in his posting.  I have indeed
noticed that the Seagate ST-238 in particular goes though a rather
lengthy g-r-r-r-r-r recalibrate noise at the next reboot after it
has been "parked" with the shipdisk program on the diagnostics
disk.  The ST-238 doesn't do that if it is just powered down.
Actually, we've never lost an HDU, except for the full height 10
meg unit on one IBM-XT.  Oh yes, a 30 meg HDU on an altos 586, but
it got zapped by lightning, so that doesn't count for vibrational
damage.
