Bob,
I've seen this work with IDE drives that wouldn't spin up due to bad
bearings.
Freeze the drive in your freezer then spin it up while it's still frozen.
This seems to free the bearings for a short time so the drive can spin up.
I know of a couple people who used this technique to copy the contents off a
dead drive, they required several freeze passes to get all the data as the
drive tends to warm up quickly once pulled from the freezer and powered up.
The speculation has been that the metal contracts when frozen and releases
stuck bearings, this has always seemed an
'Odd' explanation as the bearings and races should contract at the same rate
assuming similar materials.
Of course this is a last resort option and your experience may vary.

Is there a repository of information regarding reviving
old hard drives?
Specifically, I have a Seagate ST3390N in a Mac Iici
that appeard not to
spin-up anymore. I'm wondering if there are any
"tricks" that might get
this
drive running again? It's got my running copy of
Opcode Vision on it, and
I've not found any newer MIDI sequencing software
that runs on current
systems that I'm more comfortablr with... I'd
love to get my Vision running
again!
