VAIO® Notebook User Guide
Always use the AC adapter as the power source for your computer when you are writing data
to a CD-RW or CD-R. Using battery power may result in data transfer failure.
Do not strike or shake the computer while writing data to a disc.
For optimal writing speed, deactivate the screen saver before writing data to a disc.
For best results, use CD-Rs that are compatible with 4x speed, as DirectCD™ and Easy CD
Creator™ are preset to that speed. Your notebook does not support 1x writing speed. If you
use CD-RW or CD-R writing software other than DirectCD, use PowerPanel to select the DVD
Profile. Memory-resident disk utilities may cause unstable operation or data loss. Deactivate
these utilities before writing data to a disc.
Exit anti-virus software before writing data to a disc.
When using Easy CD Creator™ Standard, be sure to close and exit all other applications.
If your notebook computer has preinstalled Microsoft® Office applications, such as Excel,
Word, and Outlook, turn off the FindFast application.
Do not put your notebook into power saving mode while using DirectCD to write data or
while using Easy CD Creator.
