Bad CRC indicates a data transfer problem between the drive and the
controller. The CRC is computed one end and verified the other. The OS
isn't directly involved.

This usually means either
#1 A 40 wire cable in use for > UDMA33
#2 A drive plugged into the middle of the cable and none on the end
#3 The short part of the cable connected between a drive and the
controller not the long part

And occassionally it may indicate power, iffy connectors or electrical
noise problems.

Theoretically it can also be caused by the kernel misprogramming the
timings but the old VIA IDE driver is very well tested in this area and
the one bug I know it has with timing it always sets to be excessively
safe not problematic.
