There are a number of CD-ROM mechanisms that seem to interpret the
ATAPI standard in ways that pcd does not understand.

Among the messages that you see in the kernel log should be the identification
string from the drive. (Different batches of MSI drives have different
mechanisms in them.)

How so ? The unit number is the last two digits of your drive's serial
number, unless you have reprogrammed it.

This is not surprising, there haven't been any changes to PARIDE since that
disk was prepared.

I don't have any easy solutions. You've probably already sent me your
verbose=2 traces, but if not, please do so. Perhaps I'll see something
this time.
