I've now stressed the new disk for almost a week and seen no indication 
at all to the previous error. Everything else is the same as before - I 
even installed from the very same DVD. My conclusion is therefore that I 
really had a disk that was broken in a way that normal tests will not 
detect.

Hence, my tip to anyone having a similar experience: Don't blame the 
driver, nor the motherboard/chipset - just replace the drive. It would 
of course be even nicer if the error message could spell this out 
somewhat clearer too, but I guess the "I/O error" in the middle is a 
fair hint in retrospect.
