The remedy sounds like it solved your problem, but I don't understand
why there mere use of the drive cache, which should be transparent,
should cause CRC errors directly.

Maybe there is an underlying issue with cable length or quality vs the
UDMA speed in use with it... when the cache was enabled the drive could
spew back data fast enough to show the problem?  Just a guess that maybe
dropping down a UDMA level or two might also make the problem go away.
Although it being a VIA chipset, anything is possible or even likely.
