Jules,
That sounds like a spindle motor bearing that is going bad. Yes, it
will get worst and the motor will fail to spin up at one point. I
wouldn't use this drive for anything that is important. Remember these
motors don't have a lot of torque.
GOD Bless and Thanks,
rich!

I picked up a couple of 9GB Seagate Elite SCSI disks the other day
(model 410800N, 1995-vintage but 5.25" FH units).
Both drives spin up, both pass r/w tests successfully. On one unit,
the spindle motor sound is constant. On the other, however, it makes a
sound that I can best describe as "reverse surging", where every 5
seconds or thereabouts there's a very brief lowering in tone before
the "normal" sound resumes.
Anyone familiar with the Elite range know if "some of them just do
that", or if it's likely to be some form of fault (which may only get
worse)? I've never encountered a disk which does this before; my ear's
not detecting any kind of speed increase prior to the decrease (and I
don't know if that's what's really going on or not), but that's what
my brain wants to think is happening. However, if the speed really was
fluctuating to the point that I could hear it then I'm surprised that
I'm not getting read/write problems.
cheers
Jules
