        I have a Supra 20Meg drive that I believe is a MiniScribe - at least
the software format program references this.  Anyway, the drive will be
sitting running quietly and I'll be reading conversations, say on P-Net, when
all of a sudden I'll get the buzz saw sound effect too.  It will fade in, last
for 15 or 20 seconds say, then fade back out.  I've been wondering if this is
some speed adjustment that the drive has sensed it needs to make.  When the
drive, on occasion, was active during this phenomenon there was no apparent
read/write problem.  I don't know if this sound effect is the same as the ones
described by the previous posters.  I am guessing that what the sound really
is is a harmonic vibration of some sort that gets started.  What sets it off
or if it is causing any damage I have no idea.
