Troubleshooting: Reading Discs
Symptom Possible
Causes
Solutions
Trying to read a CD-
RW disc in a CD-ROM
drive that does not
support it.
Use the PlexWriter to read CD-RW
discs or use a different CD-ROM
drive. Only CD-ROM drives
manufactured after 1997 can read
CD-RW discs.
UDF reader is not
installed on the system
to read CD-RW or
packet written discs
from a CD-ROM drive.
Refer to your packet writing
software manual for how to obtain
a UDF reader and install it on the
computer where you need to
access these discs.
Cannot use other
CD-ROM drives
to read discs
written by
PlexWriter.
Session was left open
on a CD-R disc and
does not have a table
of contents.
Place this disc back into 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
18.
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 manual regarding this
feature.
