Does anyone know of any resources on the web that describe the various
sounds hard drives will make before they start to crash?
Like, I know from experience that when I hear a hard drive occasionally
buzz or give out a momentary high pitched squeal, it means the bearings
are failing and it will probably eventually crash (maybe not soon, but
eventually).
Anyone have any info on this?
Thanks!

I've had 2 hard drives* fail in this way. On dismantling it was clear
that in both cases the original grease had gone hard. Both made that
high pitched squeal. Both ran for a few months like that before they
stopped turning for good.

Thus, it makes sense that the failure mode was that of the
grease going hard; this should be specially frequent at
higher temperatures.
I've had quite a few ST410800 (WD, N and W suffixes) 5.25" drives up
and running continuously for >5 years in a variety of machines, though.
They are incredibly reliable.

I'll have to check our HP service contract receipts -- we had at least three
drive failures in four years on an HP (Apollo) 715/75 workstation. Between
that and the DAT drive failures on our 9000/G40s, the legendary HP quality
seemed to be scarce in the early-90's and apparently has only gotten worse
since then, especially in their PC and calculator products.

Back in the "good old days" (15-20 years ago), a lot of the 5.25" full
height drives would make high pitched squeals, without being a sign of
impending failure. The strap that rubbed on the end of the spindle would
develod a small pit that would make noise. Pushing down on it would
silence it briefly. bending it very slightly sideways would silence it
for a long time, until it had worn another pit.
'course the same drives no longer make those noises (ever since I stopped
hearing those frequencies).
are failing and it will probably eventually crash
(maybe not soon, but
eventually).
ALL mechanical devices, including drives, will EVENTUALLY crash!
