This is not always the case.  Most of the time, a squeaking hard disk, will
be due to the the wearing of the static brush.

I encountered this problem on 5 seperate occasions with SuperMac drives.
SuperMac have amazingly modular architechture for thier HD's.  Basically
it is three parts (controller, power supply, hard disk chamber), so it
was really easy to pluck the little squealing beast from it's resting place.

If you are at all squeamish about opening your breed of HD, then your
dealer will probably be able to replace/remove the static brush for you.

I gather the idea of the static brush is to eliminate (ground) any static
build-up, so it won't go skating across the surface of your HD destroying
data on the way.

If you look at the circuit board side of your hard disk, you will see what
looks like an opening in the board.  There is a little cap like affair sitting
on top of a bearing.. that is usually the cause of the screech.  The NEC
chambers that come with the dataframe XP 40's has a little screw that holds
it in, so it is easy to remove.

I removed mine only after it was blessed and anointed by my SuperMac dealer,
so you might like to check on anything that would cause the warantee to be
voided (like clipping the staticbrush off, if it is soldered to the PCB etc).

Now children, don't you try this at home... :-)

Hope this help,

Stu.
