Yup. I know ext2 can do it. I expect a filesystem to not foul up my data
when something happens. Especially not shuffle around sectors in several
files. I can understand that the changes I made are not on disc, I can
even understand it if my files are gone, but not when it corrupts my data.
That just plain sucks.

A friend of mine has had crashes as well (not reiser related btw), where
files he was using at the time suddenly contained different pieces of
different files. It's just plain annoying. The reason why *I* use(d)
reiserfs was the fact that I thought that it would protect my data when
something does crash. From my experience, it doesn't, and I'd rather wait
a couple of minutes for ext2 to fsck than use reiserfs and be sure I can
start all over again.
