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... Civileme
