I'm not aware of any test that I could make that would
detect an error on the disk media. Even if there were
such a test, would it be worth wasting a couple of machine
cycles on *every* byte read by *every* program?

I believe that each disk sector has a checksum on it.
Perhaps your "Nero" program sees if the checksum is correct.

I would have thought that the O/S would complain loudly
if a sector were bad (i.e. bad checksum).
