about device on burning CD

[OErjan]

use /dev/hdX where X is the devicename.
something like this

cdrecord speed=1 dev=/dev/hdc -v -eject ./Knoppix4.02.iso

for DVD use

growisofs -dvd-compat -Z speed=1 /dev/hdc=./knoppix.iso

This work in 99% of cases with a 2.6 kernel.
if you type dmesg|grep CD in a console you will see what the CDburner is called.
also sudo cdrecord scanbuss dev=ATAPI might help you.
happy burning[/code]
