[QUOTE=mathf;2457840]If it is an external drive, make sure that the corresponding /dev/sgXX file is readable and writable by your user account. This is the entry point that Nero Linux will use to communicate with the device.[/QUOTE]
I found /dev/sg0 and /dev/sg1 and set the permissions to 666. Re-ran Nero but it will still only write an image file. Is this a limitation of the trial version or did I not understand you correctly?
