Ok, so I guess a good guideline for SATA disk usage is to not use the
end of the disk for important filesystems.
Or perhaps play around with RAID and carefully inspect the amount of
cylinders/sectors and verify that the disk has shrunk once before
starting to use it for important data.
Or take regular backups to a backup disk _in another computer_.. :-)
Anyway, I have toggled all SATA/IDE/RAID settings I can find in the
BIOS but the last cylinders are not shown for NetBSD. I did not play
with these settings before the "shrink event", so I guess that
something happened before or during the hang+restart I wrote about
