Well, I'll be leaving tomorrow afternoon to pick up the VAX 8600 lot
at Austin. I have a question regarding the locking of heads on the
RA81s. When I've hauled one before, the owner already had it locked
and ready to go. The status of the RA81s at Austin is unknown. I
seem to recall that the heads should be locked only while the disk
is spinning or scrapage of the platter will occur.
My question is this: assuming the disks are not locked and there is
no way to spin them up, should I haul them unlocked or go ahead and
try locking them?

I'd never heard of this on an RA81. The two I got yesterday were locked
up while stopped, under direction of two sysadmins who have been working
with this stuff for a long time. The disks certainly don't say anything
about it.

while at DEC with no problem. However, they were spun down and fully
parked (I think they had a landing/parking zone) before I locked them.
I was warned about the locking them while spinning only after I'd worked
on at least 20 or so with the fatal glue stiction problem.
Now, Eagles always got locked down the right way.
