Information on burning CD-Rs/CD-RWs 
 
 
Caution 
Data may be corrupted when burning CD-R or CD-RW!  
Burning is permissible only in an undisturbed environment, i.e. shock and vibration stress 
must be avoided. Because of heavy fluctuation in the quality of CD-Rs, data may be 
corrupted in a burning session, even if no error message is initially displayed. The written 
data can only be verified by comparing these with the source. To be on the safe side, data 
should be verified after every burning session. When backing up an image, the data should 
be restored to the hard disk and the system should be rebooted from the hard disk.
