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.
It's difficult to say without seeing the dmesg output from the newer
kernel. However, from the output you posted above it seems that you may
not have any hardware-specific IDE driver enabled in your kernel
configuration and it's using a generic driver. I believe this mode isn't
supported anymore, at least not by default.
