Symptoms
A CD does not work.
Action
v Verify that the disk is inserted correctly, with its
label up.
v Make sure that the disk you are using is clean. To
remove dust or fingerprints, wipe the CD with a
clean, soft cloth from the center to the outside.
Wiping the CD in a circular direction might cause
loss of data.
v Verify that the disk you are using is good and not
scratched or damaged. Try inserting another disk
that you know is good. If you cannot read from a
known-good disk, you might have a problem with
your drive. Check that the power-supply cable and
signal cable are securely connected to the drive (see
"Removing the cover" on page 45 for cover removal
instructions).
v Use the Configuration/Setup Utility program to
verify that the drive is enabled (see "Chapter 4.
Using the Configuration/Setup Utility program" on
page 29).
If these actions do not correct the problem, run the
diagnostic programs (see "IBM Enhanced Diagnostics
program" on page 92). If you need technical assistance,
see "Chapter 7. Getting help, service, and information"
on page 99.
