When I worked for Imprimis, we used to pull the strap off the drive. I've
never had any problem with this approach. I find the squeal that the strap
makes intolerable. What about corrosion due to the graphite lubricant? The
reason you don't see graphite used so much as a lubricant anymore, is that
it was found to be a major source of corrosion.
 
I obviously cannot take responisibility for anyone pulling the ground strap
off thier drive, but I've never had any ill effects. Followups to some
hardware group, or by mail. This is _way_ off-topic for c.s.a
