Well, our drives made terrible noises when they spun
up the first time
after many years. My first thought was bad bearings (singing and
screaking like old HDDs), but otherwise the drives worked fine, so I just
ignored (and somehow even enjoyed ;-)) the noise. But the noise went away
after a few hours of running, so I think the bearings (the grease or
whatever) have "recovered" from sitting there unused for such a long time.
But it may be possible that you really have bad bearings or a bad motor.
I am totally cleueless about THOSE drives, but, 25+ years ago, a lot of
hard drives would squeal or shriek from the pad rubbing on the end of the
spindle.
Pressing it harder against the spindle would sometimes work, but not for
very long.
Some people would pry it away, or rip it off!
But, in most cases, deforming it slightly to move it SIDEWAYS a tiny
fraction of a mm would let it get started on a new wear spot, and silence
it for years.
