Great to hear that this has changed. :)

I run weekly SMART "long" tests on all my disks because, in my
experience, that has been the best indication of impending disk
failure. It performs a full surface scan, so on a 2TB disk this can
take 6 hours (maybe more on green disks).

Something like this in smartd.conf:

/dev/sda -a -H -l error -l selftest -f -m marti at juffo.org -s L/../../3/11

checks for attribute changes and performs a long test every thursday
(3) at 11 o'clock and emails me about problems.
