Summary: fast-moving parts *should* be sealed

I have some older Winchesters with transparent plastic HDA housings
(Fujitsu 2284, 2298).  When I had one hanging out on its slides for
seek adjustments, with only thin plastic between the 125-MPH platter
edges and my stomach, and the heads banging against the stops when I
adjust too far, I can never help wondering "if this crashes, will I
live?".  It gives me the creeps.

While lying under a 2298, pulling a cable snags the power switch and
the belt starts moving inches from my head.  (I have long hair...)

I have to caution every field service person about our ancient 9766
top-loading disk drive with no door interlock, worrying that one of
them is going to open the top while it's spinning and get his necktie
sucked in.

Dangerous moving parts *SHOULD* be sealed!
