And a journalling fs is not necessarily going to help you with that case
due to hardware issues. Harddrives, especially on commodity level equipment
like PC's, have been known to write garbage as power fluctuates during a
write in this kind of scenario. So you may well journal garbage as well.
Not necessarily a big improvement.
