Another thing I do is every month for each partition I fill 
the empty space with 0's

dd if=/dev/zero of=zero.zero; rm zero.zero

(doing this even on the root partition hasn't caused any 
crashes in the years I've been doing it).

I do this for 2 reasons, neither of which I've needed.

o if ddrescue partially recovers a sector with almost all 
0's, I know I can ignore it.

o if I have to do an unerase, I know which sectors to 
ignore. However I haven't figured out how to recover erased 
files - I couldn't understand the instructions with 
sleuthkit etc - and I assume I'm never going to be able to 
use this feature.
