smartctl says that SMART overall-health self-assessment is passed.
I've tinkered around with badblocks and the results are surprising. I
really hope this is not a case of bad hard disk that intermittently
decides to act up.
badblocks gives the same errors as when copying files into the drive.
*However* badblocks reports 0 bad sectors and no libata error if I
test the exact same sectors it reported were bad *immediately after
the previous (errored) run* (no cooldown/reboot/etc) It might have to
do with length of SATA bus activity? I get both libata and badblocks
errors around the 60000000 sector range after badblocks has been
running ~1 hour into a test. if I just run badblocks over those
reported blocks, it always shows up fine, no libata or badblocks error
(including badblocks -w)
I experience the errors only on the reading phase of badblocks, not
the writing phase. Also, as said above, I get zero errors when I
repeat badblocks -w over any specific "problem" areas. This cycle
repeats itself. (if I run a full drive scan, similar errors occur. if
I check just those "bad" blocks, they disappear)
I'm going to try starting a long block scan from a different address n
and see if the reported "bad" blocks show up around the n+60000000
sector range.

I just patched my kernel. The new error messages are below.

Yup, 2.6.16.1
