I have recently made quite a few people happy by pointing out an easy fix
for *some* whining hard drives. While some whining is caused by head/disk
interference or a bad bearing, many times it is caused by the vibration of
the small brass grounding strap that makes contact with the spindle of the
drive mechanism.

The fix is simplicity itself. Just play with the strap, increasing
(usually) the tension, decreasing (not usually) the tension, or just
forming the strap to make it ride on a different spot against the spindle.
The strap may or may not have a carbon 'button' on it. If all else fails,
use a little graphite lubricant (very sparingly).
