The other thing you mentioned but didn't comment on the condition of is
the grating and the optical sensor for said.  are they clean?  also, on
the drive's we had, of the western dynex and microdata variety, you
could physically feel the drive or the voice coil and feel it vibrating
when there was a servo problem, in most cases, or hear a difference
in the seeks as it failed.
