A CD or DVD does not work
Symptom: A CD or DVD does not work.
Actions:
• Verify that the disc is inserted correctly, with its label up.
• Make sure that the disc you are using is clean. To remove dust or fingerprints, wipe the disc clean with a
soft cloth from the center to the outside. Wiping a disc in a circular motion might cause loss of data.
• Verify that the disc you are using is not scratched or damaged. Try inserting another disc that you know
is good. If you cannot read from a known-good disc, you might have a problem with your CD or DVD
drive or the cabling to your CD or DVD drive. Make sure that the power cable and signal cable are
securely connected to the drive.
