We've seen the same problem in a 40MB internal drive on a Mac II.  This Mac II
is about 18 months old and has the Apple drive (Quantum?).  The symptoms
are that when you turn on the power to the Mac, the drive doesn't spin
up.  Thus, the Finder does not see the drive and blinks the question
mark at the center of the Mac icon on the screen.  Our solution is to bang on
the side of the Mac right before turning on the power.  A few good shots and
drive powers up and works normally.

Unfortunately, due to sometimes erratic temperature fluctuations in our
building in the evening, the guy who has the Mac II has to turn it off
at night lest it fry.  He's been beating on his Mac every morning and gets
some strange looks from onlookers in the hallway (we're mostly a PS/2 company
and this doesn't help the image of the Mac).

We bought the Mac from Businessland and they have made some noises about
replacing the drive although I don't know the final disposition.
