Interesting FYI ... Like anyone who has been around
the early days of
micro HDs, I have heard HDs make an attention getting squeal. After a
while, we knew/found out that it was caused by the grounding spring on
the bottom of the drive, and bend it out of the way. In glancing through
some old Compaq Service Bulletins, I saw IN PRINT that the fix was to
remove the grounding strap with the comment that the drive is adequately
grounded though other contact points.
I've been doing that since, oh, 1985 or thereabouts.
Uneven wear on the graphite button on the grounding strap is usually the cause
of the noise...
