Troubleshooting
Errors occur when backing up at 6X or 8X speed from a separate CD-
ROM drive to the CRW8824SX drive.
● A possible reason is that the CD-ROM drive is not suitable. Please use a high-
speed CD-ROM drive. However, for various possible reasons, you may still
encounter errors even if you are using a 32X or 42X speed CD-ROM drive.
Therefore, before writing directly at 6X or faster speed, you should check that it is
possible to do so by choosing to test before writing.
The “Buffer Underrun” error message is displayed.
● Try the following:
• Lower the writing speed setting.
• Create an image file of the CD on the computer’s hard disk.
• Defragment the hard disk.
• Turn hard disk power management off.
• Deactivate the Active Desktop (if you are using Internet Explorer 4 or 5).
• Disable network access.
• Close other applications (including screen savers, task schedulers, etc.).
n Errors can occur if you knock the CRW8824SX drive while it is writing to disc.
n When using packet writing on a CD-RW disc, the actual data capacity is 100MB less
than that stated on the cover of the disc. The difference in capacity is dependent on
the writing mode.
No sound is audible when playing back CD-DA (audio CD) discs.
● Check that the Line OUT (L/R) connector of the CRW8824SX is connected
correctly to your sound card or amplified speakers.
