DVD-ROM/CD-RW
The DVD-ROM/CD-RW drive is an optional feature. Recording methods supported by the
disk drive: Disc at once, Track at once, Session at once, Packet writing, whereby Disc at
once und Track at once are recommended due to their compatibility to other CD drives.
DVD-ROM, CD-ROM, CD-R and Video CDs can be read.
Burner/DVD player software
To utilize the full functionality of our DVD-ROM/CD-RW drive, you need to install additional
software (burning or DVD player software). This software is included on the CD supplied with
the device. Insert the CD in the drive, run setup and follow the instructions on the screen.
Notice
When first starting the burner software, no data carriers should be inserted in the drive. This
is because data carriers with errors can interrupt the automatic hard drive recognition. This
makes it impossible to correctly display the possible burner functions.
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.
