CDRW doesn´t work anymore

[KeTZer]

My Kernel is tainted because of the NVidia Drivers, which I use.

dmesg|grep *
with any of the devices suggested does not give any output...

Thank you people for the help, but the problem has solved itself as I tested the drive in another computer and it wasn´t recognised by bios. Shortly after this some chip in the drive got extremely hot and left for chip heaven...
