The OS can typically revert a drive down to PIO mode if it detects driver
errors, including CRC. But, other tricks that can trigger it include having
zips/isos/imgs that were mastered with CRC errors when in fact the drive
housing them is perfectly fine.

Good call...it did change the IDE drive down to PIO mode.
Why would it do that?

Do not test the SMART Gods, you should bow to them for giving you a
warning.
YMMV.
As far as the CRC goes, I would first make sure your OS did not dumb down
the IDE drive to PIO mode.
