Cannot Read or Write Discs.
• Is the condition of everything else in the system (CPU, hard disc, and others) as it should be?
(See system environment page 2.)
• Does the CD-R, DVD or CD-RW disc have dirt or scratches?
• Did a screen saver or other application operate while writing to the disc?
• Is there enough free space on the CD-R/RW disc?
• Does writing fail even using the simulation test?
• Is the disc loaded in the drive with the read/write surface facing the right direction? (label up)
• Is the drive installed in the correct orientation?
• Was the drive or disc moved from a low temperature environment to a high temperature environment?
(There is a possibility of condensation on the lens in the drive or on the surface of the disc.)
When you call for service, be prepared to give as much information as possible of your system, environment,
and the specific problem. (What happened? When? How long? What was going on? Were there any error
messages displayed? etc.)
Please Note:
Since this product supports Region Playback Control Phase II, a certain MPEG decoder card or
Software without regional code setting may cause this drive not to read DVD-ROM discs. This Drive enables
you to change the regional code up to 5 times.
Read Speed Control for CD-R Data CD
The basic default reading speed for CD-R disc media in this drive is 40X. The Read Speed Control will allow
you to select the maximum read speed (52X) for CD-R media, simply by pressing the eject button. Note that
this function is only available with a CD-R data disc. To enable 52X CD-R read speed, follow the chart below:
Flow Chart
Open the Disc Tray
Load CD-R Disc
Close Disc Tray
Initialize 52X READ
Operation
User instruction
(Push Eject /
button)
(Put CD-R disc on Tray)
(Push and hold the eject
button for more than 3
seconds)
The LED indicator turns on for 3 seconds. The 52X maximum read speed
for this CD-R disc has been enabled. The Read Speed Control will allow
you to select the 48X maximum read speed for CD-RW Data CD.
Ejecting this disc or turning off the PC will disable the 52X maximum read
speed function. The drive will default back to the 40X CD-R read speed.
CAUTION:
The quality of CD-R data disc varies significantly from brand to brand (or brandless), as well as disc condition used over time. A disc that is poorly balanced
or that may have cracks in it greatly increases the chance of disc failure or disc shatter when being read back at speeds higher than 40X, possibly causing
damage to the drive. Closely inspect discs you plan to use in the drive for any abnormalities or cracks. If you hear strange noise or sounds from the drive
during operation, this could be a sign of an unbalanced or damaged disc and it should be removed immediately. LG Electronics does not warranty drive
damage caused by faulty or shattered discs.
