...
  Quite a few years ago, I scrapped out a big drive that
had an arm
 with very fine brushes that would sweep the platters just after the
 thing came to speed. 
   DEC RP04s (Sperry drives, IIRC) had that as a feature. It was later
found that the brushes did more damage than good, and the brushes were
subsequently all tied back with wire-ties as per an ECO.
