CD and DVD drive safety
CD and DVD drives spin discs at a high speed. If a CD or DVD is cracked or
otherwise physically damaged, it is possible for the disc to break apart or even
shatter when the CD drive is in use. To protect against possible injury due to
this situation, and to reduce the risk of damage to your machine, do the
following:
v Always store CD/DVD discs in their original packaging
v Always store CD/DVD discs out of direct sunlight and away from direct
heat sources
v Remove CD/DVD discs from the computer when not in use
v Do not bend or flex CD/DVD discs, or force them into the computer or their
packaging
v Check CD/DVD discs for cracks before each use. Do not use cracked or
damaged discs
