This section provides tips on protecting data stored on your CD/DVD.
Handle your media with care. The following simple precautions will
increase the lifetime of your media and protect the data stored on them.
CD/DVD
1. Store your CD/DVD in the container they came in to protect them and
keep them clean.

3. Do not write on, apply a sticker to, or otherwise mark the surface of the
CD/DVD that contains data.

Fingerprints on the surface can prevent the drive from properly reading
data.

cleaner. Do not use benzine, thinner or similar cleaner.
