Solutions to Some Common Symptoms
Hard Drive compression software.
We do not recommend using hard drive compression software. If you use
hard drive compression software, it estimates free hard drive space based
upon a compression ratio (often user selectable). Programs may check
your hard drive for space needed and may think you have the necessary
free space. However, depending on the type of files you are copying, you
may in fact not have enough hard drive space.
Achieving optimal performance.
Run SCANDISK.EXE and DEFRAG.EXE on your hard drive before using
your CD-Writer Plus drive for the first time (see your Windows manual
for more information). Then run them periodically after that. These
programs improve access times to the hard drive, which will help
improve system performance while writing to and reading from the CD-
Writer Plus drive.
Buffer underrun error messages.
CD recordable devices require an uninterrupted data stream from the
hard drive in order to write successfully to a CD. A buffer underrun
message appears when for some reason the data stream is interrupted.
This can occur, for example, if another application interrupts the writing
process, or if the CD-Writer Plus drive’s write speed is set too high for the
speed at which the hard drive can accesses and transfer data.
When using Easy-CD Creator or Disc Copier:
■
Make sure you use the Test option in the software to ensure that the
write speed is appropriate for your computer. For more information
see the application’s online help.
■
Make sure your system meets the minimum system requirements, see
Minimum System Requirements on page A-1.
■
Buffer underrun may be caused by hard drive compression software
(see page 3-6).
■
NEVER write to the recordable CD while other applications are
running that could interrupt the writing-to-CD process. Log off any
networks, disable any fax modem, email, screen saver, or other
programs (such as TSRs, terminate-and-stay-resident programs) that
may automatically send messages to your computer while writing
data to the CD. If the interruption is long enough, you could ruin a
write-once CD to which you are writing.
■
Exit any other programs before writing data to the CD.
