Lets add in 'environmentals' too.
Ive been on site and seen:
120d ambient temp machine rooms.
Racks with running filers being moved across a room by hammering a pipe at the
base of the rack.
Shelves dropped.
Drives dropped.
Heads dropped.
A & B power supplies all on the same curcuit (causes FCAL brown out badness in a
lot of cases)
Leaky styrofoam cups placed on the filer head.
Drives SLAMMED home when replaced/installed by customer.
Stripped screws securing a shelf having the heads hammered off with a
chisel..with the shelf/drives still spinning
..and the winner...
...a serial cable in place of a FCAL jumper cable.

Actual field numbers would no doubt be greater, since you are
dealing with a wider variety of drives over history (presumably
some less reliable than the current ones) and you also have some
rare software / firmware bugs that probably necessitated a restore
once or twice.
