Yeah, I had thought about that too, but this drive
doesn't have a physical head lock - and the drive
seeks fine during it's power up self-test. Also, the
front panel diagnostics run fine - i.e. the random
seek test. Something's getting screwed up in the
command translation from the computer to the drive.
I've tried setting the drive to 86 sectors that's
listed in the Emulex manual as the default for this
drive. Same results. It actually tries/buzzes for a
good minute or so, not the 30 seconds I originally
thought. I've tried every combination of settings on
the drive I could think of. I am obviously missing
something... The drive is properly terminated, and I
double checked all the cables.

After entering
the
relevant settings (from the manual) for the hard
drive, the controller will sort-of talk to the
drive.
It shows it as being available, but when I try to
format it, the drive makes a buzzing noise for
about
30 seconds, then I get the message that
"This
operation timed out". When I answer the error
message
with the enter key, the buzzing from the drive
stops.
Is it possible that the drive's head restraint is
still
activated/in-place?
That'd certainly cause the buzzing, with the
voicecoil positioner
attempting to move the head when it's locked in
place. These big old
drives with rather massive head carriage assemblies
always had some
means by which the head could be locked into a home
position for
transportation purposes. Sometimes it was an actual
screw that was put
in place to hold the head in place, or some kind of
cam-activated
mechanism that would lock the head.
Just a thought...
