Lost power to the computer or had to press CTRL-ALT-DEL
while writing to the CD!
If you lose power while writing to your CD (the CD-Writer Plus drive's
red light is on) OR If you exit an application or press CTRL-ALT-DEL
while writing to CD...
You may be able to salvage your CD, but ONLY if you:
1. LEAVE YOUR CD IN THE DRIVE, DO NOT OPEN THE CD TRAY
2. Turn your machine off
3. Turn it back on
4. Then re-enter the application you were using
Once the application tries to access the CD-Writer Plus drive, the
recovery operation will make it appear that the last session is there.
However, in reality, only a part of the CD's directory may be there. Your
recordable CD is still usable if you can read the directory. Repeat the
entire copy operation to make sure that your files are copied to the
recordable or ReWritable CD.
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.
