Please investigate the CMOS settings for your parallel port. If possible,
change the port to "EPP" mode.

Ok, the bpck protocol driver located your backpack, and was able to
communicate with it - but it failed a data integrity test.

The integrity test failed because of an oddity with your specific
port, that MSI's driver's understand, but ours doesn't. If you can
get into EPP mode, this specific problem should go away.

By pure coincidence, your drive happens to have an ID number of 46.
(That's the last two digits of its serial number.) 46 is also the
major device number for the pcd driver - there's no relationship
between them.
