Sounds like a good idea. However, I had the drive swapped yesterday and
have now reinstalled on a (seemingly) identical one which so far seems
to be free from these messages. Hence, I keep my fingers crossed that
this was indeed a hw error.

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.
