The DVD burner drive is an optional feature. Recording methods supported by the disk drive:
Disc-at-once, Track-at-once, Session-at-once, Packet writing. CD-R, CD-RW, DVD+R,
DVD-R, DVD-RW and DVD+RW and dual layer media can be used.
Burner software
To utilize the full functionality of the DVD burner, you need to install additional software
(burner 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.
Notes on burning optical data carriers
Caution
Danger of data errors when burning data carriers!
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.
