When I worked as a technician for AT&T, we had a (semi-)permanent fix
for this problem.  We used a syringe to place a small amount of
graphite (which I believe was suspended in a viscous material) onto
the strap.  I used a drive which had this problem, and after the
graphite application it ran for over two years without so much as a
squeal.
