Plextor PL-6P3 Operation Manual page 20

Symptom
Low Performance of CD-ROM Application Software
Possible Cause and Solution
Drive Automatically Set to Standard Throughput (150KB/sec)
Plextor's drives are designed to automatically switch from six speed throughput
(900KB/sec) to quad speed (600KB/sec) and then single speed (150KB/sec) when
they encounter a defect or a scratch on your disc. The drive then will continue to
read data from the disk at quad or single speed until a new read command is
transmitted to the drive. The drive will then return to six speed mode.
It is also possible that the disc is dirty. Please refer to page 44 for instructions on how
to clean your CD-ROM disc.
Symptom
Disc is Ejected After Being Inserted
ON/BUSY Light Flashes 4 Times
Possible Cause and Solution
CD is unreadable
Plextor's drives are designed to automatically eject any unreadable CD. Please be
sure that the CD-ROM disc, or audio CD is ''Label-side'' up in the caddy. If not,
this will cause the drive to eject the CD. A blank or incorrectly written CD-R (blank
media), a damaged, scratched or otherwise unreadable CD will cause this same
symptom. Inserting a known good disc will correct this problem.
