This drive may be so old that it uses an older version of the backpack
protocol that is not supported by PARIDE.

I know of three versions of the backpack protocol. The first version
was used with some non-ATAPI CD-ROMs and early IDE hard drives. The second
is used in all current products except the CD-RW drive. The third version
is used in the new CD-RW drives. At this time, only the second version
is supported by bpck. There will be a driver for the third version soon
but it is not ready yet.

Now, back to your problem. Please try loading pd with

        insmod pd verbose=1

and report the kernel log messages. (Use dmesg to retrieve them.)

Unfortunately, I don't remember the mapping of product codes to protocol
