CD and DVD drive safety
Danger:
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 computer,
do the following:
Always store CD/DVD discs in their original packaging.
Always store CD/DVD discs out of direct sunlight and away from direct
heat sources.
Remove CD/DVD discs from the computer when not in use.
Do not bend or flex CD/DVD discs, or force them into the computer or
their packaging.
Check CD/DVD discs for cracks before each use. Do not use cracked or
damaged discs.
