	The info file is _DEFINITELY_ needed.  It contains information as
to which piece of hardware the driver is for.

	Sounds like crashed heads.  Was it subjected to any shocks or bumps?
(including the table it sits on)  Could also be the anti-static bruch under-
neath the spindle, which keeps the platters from building up a static charge.
It is usually designed to rub against the bottom of the spindle.  You could try
carefully bending it away from the spindle, and see if the noise persists. 
Note: caveat user (let the user beware), don't do this if you don't know what
you're doing, and I suspect it will void your warranty.

	Some drives sporadically make lots of noise: particularily Rodimes.
I have such a rodime, it can make some nasty squeals, but has never lost any
data.  Commdore uses rodimes in some A2500's, I think.  Quantums are _very_
quiet, but run hotter.
