To pinpoint, you are listing wrong speeds. You are listing FSB speeds
while you should be listing PCI bus speeds :
FSB/PCI
66/33 (1/2)
100/33 (1/3)
112/34 (1/3)
75/37 (1/2)
83/42 (1/2)
133/41 (1/3)

as you see, the speed of the PCI bus grows, and the time between PCI
bus "clocks" shortens. This might be enough for something to take too
long - for example, slow buffer memory in HD will not work fast enough
to fit into one PCI bus cycle.

Sometimes by lowering the PIO level of the drive you can fix the
errors, but this will slow the data transfer HD<->PC as well.
