• It may be necessary to write audio at slower speeds than those
you can achieve for data, since writing CD-DA audio requires
streaming more bits per second to the recorder.
• Record in lower speed – it takes linger time to empty the buffer
when recording at lower speed.
• Keep the CDs, the recorder, and your source CD-ROM drive free of
dust.
• Close all other application programs.
• Disable the screen saver and anti-virus programs.
• PC power management makes PC slower and thus it may result in
buffer underrun. Disable the power management or delay the
power saving time.
• Keep your CD-R/CD-RW cool. Sometimes the drive fails when they
overheat.
• Your system must fulfill the minimum configuration of your CD-
recording Mastering software.
• Do not try to copy empty directories, zero byte files, or files that
may be in use by the system at the time of recording.
• If your data includes more than 10,000 very small files, create a
disc image first, or record at a slower speed.
• The temporary directory should always have space free at least
twice the size of the largest file you are recording.
• Try a different brand of recordable disc.
Q: Cannot directly copy from one CD to another.
• Some CD-ROM disc will not allow direct copying to the CD-ReWriter
or are not capable of digital audio extraction.
• You need to have a supported CD-ROM drive to use as your source.
• Some CD discs may have copy protections or other features that
do not allow a CD-to-CD copy.
Q: Poor audio quality.
• Make sure the audio cable is connected completely between the
sound card and CD-ReWriter or CD-ROM.
• Make sure that you do not have any sound-muting feature turned
on by way of the monitor or software.
• Try listening to the wave files (.WAV) on your hard drive to see if
they sounded poor before you copy them to CD.
Q: Unable to see a second session reading from a CD-ROM drive.
• Eject the CD and re-load it.
