Andreas Jellinghaus replied to me with useful advice. But he didn't really
answer my questions. Please, if anyone knows the answers to my questions,
please kindly say.
(Why the sectors were numbered so strangely,
what does Linux do with them after detecting them,
and how to know if the errors occured during writes or during reads.)
Anyway,

Good idea, thank you.

It's essentially my crash box at the moment. But I didn't expect visible
errors on a 2-year-old disk. (Of course the magnetic layer always has
errors but I didn't expect things to get beyond the firmware's automatic
assignment and writing of replacement sectors.)
And my reason for posting is that the error logs didn't look the way I would
have expected, regarding the sector numbers and the repetitions.

1. There are none.
2. If the connector on the motherboard were coming loose from the
motherboard, or if the motherboard had a crack causing intermittent failures
in some of its connections, surely the I/O errors would be far more numerous
and far more random than the strange occurences I observed.
