A buffer underrun is a
common error condition
that occurs when the flow
of data from the source
device (for example hard
drive, DVD-ROM or CD-
ROM drive) to the CD-RW
drive is interrupted long
enough for the CD-RW
drive's buffer to be
emptied. Once a buffer
underrun occurs, the CD
creation process is halted.
To successfully create a
CD, a continuous data
stream must be maintained
at the selected recording
speed.

Preventing Buffer Underruns
Note: If a buffer underrun occurs during an actual write operation rather
than during a test operation, the CD may be ruined.
Try closing other programs (disable screen savers, virus
➜
software, and other tasks or applications running in the
background).
Defragment your hard drive.
➜
Make sure that the temporary files are created on a local
➜
hard drive. Do not assign the location of temporary files to a
directory on a network drive. Set the location for the
temporary files by selecting the Options command under the
Tools menu.
Record at a slower speed.
➜
Do not record across a network. Copy the desired files or
➜
folders to your local hard drive.
Check the Auto Resync box under Drive Properties (for the
➜
source drive).
Note: The Easy CD Creator software automatically turns on a feature called
Audio Resync. Audio Resync helps the drive resync the buffer so that the
extraction is clean without audio dropouts. When Easy CD Creator tests the
drive, there are two read audio commands used at different parts of the CD:
the center, the middle, and the outer edge. If there is dropout or slow
extraction, it automatically turns on Audio Resync. Audio Resync affects the
performance of the drive by about 50-60 percent, causing the audio
extraction speed with resync on to be slower but more reliable.
