Troubleshooting: Reading Discs
Symptom
Possible Causes
Solutions
Session was left open
on a CD-R disc and
does not have a Table
of Contents.
Place this disc back into the
PlexWriter and use the same
software originally used to write to
it. Then close the session/disc.
Excessive noise.
Excessive
vibration.
Slow read
performance.
CD is poorly balanced.
Poorly manufactured
discs or discs with
poorly distributed ink on
labeling cause
significant vibration at
high speeds because
they are out of balance.
Read errors may also
occur.
If the disc label
(especially adhesive
labels) adds more
weight to one area of
the disc than another it
can also cause the disc
to be out of balance.
Remove the adhesive label, if
present. Be careful not to damage
the foil underneath.
Clean the disc as detailed on page
20.
If there is no foreign substance on
the disc, contact the disc
manufacturer for a replacement.
Can read only
the last session
of a multisession
CD-R or CD-RW
disc.
“Import previous
session” or a similar
feature was not
enabled when the
multisession disc was
created.
Use CD-R or CD-RW mastering
software to import session(s). Such
features may vary in name
depending on the software being
used. Please refer to the
appropriate online help or manual
regarding this feature.
