What you need:
- a good earing
- smartmontools
Indeed, so far, I haven’t found anything better than launching a process making a lot of disk activity.
This command just do it:
% sudo smartctl -t short /dev/sda
The “short” test will give you a few minutes to carefully listen and select the right disk.
Well, it sure is pretty primitive! But do you know anything better?
By the way, there is a good article for the recovery procedure.
