Long story short, it's my server and rarely ever gets turned off. I
turned it off during the hot weather to save on the A/C bill. When I
powered it up again, the drive will not spin up. The controller sees it,
tries to tell it to start, it won't listen.
Anyone have any ideas that might get it spinning again? Anyone got a
reliable, cheap 36GB Ultra160 drive - cheap? (yes, I did say cheap
twice :) )
Possible it's a mechanical hangup (bad bearing). Try taking it out and
give it a twist with your wrist, to spin the platters with respect to
the case. I'm not sure if I've had that work, but I always thought it
might.
I had a SCSI drive quit this summer too, in much the same situation. The
controller doesn't even see it.

Well, if the card can't see the drive, then that tells me the drive
electronics have failed. In the older days of IDE, I was able to swap
electronics with the same make/model of drive and get things to work.
If it's a bearing problem, then that's an entirely different animal. Never
tried to swap out platters into another frame and see if it would work.
I did that once.
First, I took apart another bad drive (same manufacturer and similar era
and capacity) to see what all tools might be needed. Then I put all
such tools into a clear plastic trash bag along with the drive of
interest and it's surrogate. I sealed the bag (hoping no other tools
would be needed), gutted the surrogate and transferred the guts of the
drive of interest and put the cover back on. It worked. We got the
data off immediately. But just for grins, I continued to used the
drive, mainly just stuff like burn-in. It continued working like a
champ. SpinRite never found another problem on it.
But even *ONE* dust particle (or even smaller, a smoke particle) would
have wreaked havoc. I recall being told that a smoke particle clinging
to the platter hitting one of the heads would be akin to a 747 flying 20
feet off the ground and finding a 30 foot diameter boulder.
