is it known what a long self-test does? for instance, ultimately you

that is, not just read and checked, possibly with parity "fixed",
but all blocks read and rewritten (with verify, I suppose!)
The smartctl man page is a little vague, but it looks like it does no
writing.
Paraphrasing somewhat:
short selftest - The "Self" tests check the electrical and
mechanical performance as well as the read performance of the disk.
long selftest - This is a longer and more thorough version of the
Short Self Test described above.
