  It is very likely MICRO 1 is wrong. What is much more common is that
on a drive with a ground strap touching the spindle, the strap vibrates
slightly, giving off a whine, hum, or other ominous noise.

  The best solution (my opinion) is to bend the strap slightly to one
side or the other. Note that a few thousandths (0.1mm for people with
metric fingers) will usually do it. You are bending the strap to the
*side*, not away from the spindle, so the strap still works, but a
different part of the strap rubs on the spindle. This still protects
against static but doesn't make noise.
