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 4.5 speed throughput
(675KB/sec) to double speed (300KB/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 double or single speed until a new read command is
transmitted to the drive. The drive will then return to 4.5 speed mode.
It is also possible that the disc is dirty. Please refer to page 48 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.
