It's strange... quite unlucky I'd say...
Maybe the check needs to be run more frequently, like weekly.
(Asdo taking notes... :-D)
I also am not expert of this kind of statistics.
FWIW I have seen two hardware raid controllers, and they do the scrub
weekly by default. I don't know if they also run SMART tests.
Also is it possible that you experienced an electricity surge or a
physical shock on the computer?
Obviously smart checks also help.
Good luck
