I could say "use XFS" but the same sort of problem can occur. _NO_
filesystem is proof against a power-down while the machine is writing to
disk(which always has the potential of destroying a low-level format).
I have seen Reiser do this more frequently than most others, but the
answer is to restore from your backup. (Well a filesystem consisting of
a chisel, hammer and stone tablets might be somewhat more secure ...)
And if you have at least a CDRW, you can backup rather simply, using
scdbackup. Bulk CD-Rs are about $.33 US each.
Naturally, I back up only my work files, usually /home, /etc, and /var...
