I'd always put silicone on the strap to change the mass.  Then I ran into
the Micropolis drives.  Their spring design is so whacky the silicone
didn't work for long.

Then, a couple of days ago, I got a call from a nice fellow named
Terry Kennedy.  He said that somebody at Priam told him that on a
3.5 or 5.25 inch form factor drive you can't build up enough static to
cause any problems.  Micropolis used to send him boxes of replacement
springs, but when asked, they also agreed that you could just rip
off the spring.

This is all hearsay, but the next time I open the case, *my* Micropolis
will be silenced *forever*.
