Yamaha CRW2100SX Series Owner's Manual page 37

The drive ejects or fails to read the disc, or the LED on the front panel
remains lit in orange after the disc has been loaded (meaning that the
disc has not been recognized). ( P. 32)
Power down the computer. Then disconnect the SCSI cable from your drive but
leave the power cable connected. Now try loading the disc.
There may be problems with the disc itself. If the drive fails to recognize a variety
of discs including audio CDs, CD-ROMs and blank CD-R/RW discs (the LED on
the front panel remains lit in orange after any discs have been inserted), you
should contact your nearest Yamaha dealer.
Errors occur when writing a disc at a high speed directly from a separate
CD-ROM drive to the CRW2100SX 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-speed or faster CD-ROM drive.
Therefore, before attempting high-speed writing directly from another CD-ROM
drive, 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 CRW2100SX 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 CRW2100SX is connected
correctly to your sound card or amplified speakers.
