[..."repairing" a disk drive whose bearings may be shot...]
Don't
expect to get good results but consider it as an experiment in
how to analyze a drive failure. One last thing is that you may need to make some
special spanners to
undo some of the fasteners.
I've taken apart a couple of drives that were sufficiently dead I
didn't care about them, and I didn't need anything but a set of torxes.
I suppose this drive may be different, but certainly all the things I
can _see_ are simple torxes....
Remember, you can't rotate the disk while the
heads are on the
surface. You'll need to make a comb like tool to lift them off while
banging and digging on things.
Actually, in the two drives I took apart, when powered down the heads
swung completely clear of the platters. I suppose when I take this one
apart I'll find out whether it's similar.
Hope this doesn't scare you. I do wish to hear
what results you
have. Also any observations you have while disassembling.
Oh, never fear, I'll report here, even if it's only "sorry, I dropped
the screwdriver on the platter, so it can't possibly work right even if
I did get the bearing fixed" :-/
The brand and type of drive are also of interest here.
Seagate ST51080N, OEMed thorugh SGI.
