[stuff about HD squeaks being due to vibration of anti-static tab]

There were reams of messages about this in the National Hard Drive
Echo. On solution is to remove the tab. I did not see any evidence
presented for or against the functionality of these tabs, although
most folks feel reluctant to remove them, assuming they serve some
purpose. It is said that newer, tab-less drives use a conductive
spindle lubricant, and that is why no tab.

A proposed alternative solution is to damp the resonant frequency
of the tabl by putting thick epoxy on the back of it. Other suggest
moving the tab slightly sideways, so that the drive spindle rides
against a new, unworn spot.

Does anyone have any hard evidence for or against the usefulness of
these tabs?
