Hello,
my old PLEXTOR CD-R PX-W1210A, FwRev=1.09 is not recognized any more in Linux 2.6.31.4.
In my old Rescue-Linux on the same machine with Linux 2.6.25.14 the CD-Writer is recognized and it works.
To give you some Information about the Plextor-CD-Burner, I booted my old 2.6.25.14-Linux:

The difference between my old 2.6.25.14-Linux and the newer 2.6.31.4-Linux is mainly the actuality of the updates (and the kernel).
I configured the kernel by my own and the changes were made with "make oldconfig" and answer the questions.
Can You please tell me if/why the Plextor do not work any more. Or better: Give me instructions to get it working again in newer versions of Linux Kernel.
Thank You.
Greetings
Mario
