The problem only exists when I use native burning apps like Brasero, K3B
or cdrecord on all Ubuntu versions including Faisty. NeroLinux has no
problem with the disk and everything works fine. I have also learned
from a colleague which owns the same drive  that the problem does not
occur on Gutsy Gibbon, and he is able to burn such disks with Brasero
etc.
