And it gets "better", just re-ran a long self test, and still got:
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed: read failure 90% 561 569442000
So, the disk sees bad blocks, SMART says there are bad blocks, and
badblocks run over the entire drive in read/write mode, finds nothing
anymore.
Anyway, those drives are going back in the box and the mail tomorrow,
but that sure is/was weird...
