On Wednesday the drive temperature hit 39 C in the afternoon (hot
weather) and I couldn't stand it any longer, so I shut the machine
down, plugged the extra case fan in, and restarted it at 18:52.  Half
an hour later, I got the errors in [1] --- but nothing since then.

Today I've run `smartctl -t long -d ata /dev/sda` and later `smartctl
-l selftest -d ata /dev/sda` with the happy-looking results in [2] and
`smartctl -a -d ata /dev/sda` with the results excerpted in [3].
Unfortunately I don't know how to read that last table --- is it
alarming?

Thanks,
Adam
