Maintenance
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.
Do not mix audio and data files on the same CD, since they require 
different formats, unless you are creating Mixed Mode or CD-Extra 
CDs. For more information on Mixed Mode and CD-Extra CDs, see 
the Easy-CD Creator online help.
Maintenance
The CD-Writer Plus drive requires no maintenance or cleaning. If you 
simply keep your CDs clean, you will prevent most problems. 
CAUTION: DO NOT use the CD-ROM cleaning CDs that rely on a small brush 
to sweep dirt off the laser. DO NOT use high-pressure air to clean the inside of 
the drive. These cleaning techniques will damage the CD-Writer Plus drive.
Identifying CD-Writer Plus’s Drive Letter
Not sure which drive letter was assigned to the CD-Writer Plus 
drive?
The CD-Writer Plus drive has a drive icon just like a CD-ROM drive icon. 
You can determine which icon is your CD-ROM drive and which icon is 
your CD-Writer Plus drive by double-clicking on the My Computer icon, 
right-clicking on the CD drive icon, and selecting Eject
