After some SCSI specification reading, as far as I can tell:

This error should not exist. That said:

0x47/0x00 is "SCSI Parity Error". A kernel with options SCSI_VERBOSE
would have decoded that for you, but of course, we need to keep
install kernels small, so it wasn't.

Now, if your cabling is broken enough to create a bit error in one direction,
it might be broken enough to create a bit error transmitting the error code
back.

My advice is:  Check your cabling. Re-check, then check the
terminators. "Worked last year" or even "worked last week" doesn't
count.
