indeed..

also, there are different journalling modes. the default one with
reiserfs, meta-data journalling can have funny effects - your fs will
always be consistent, but your data won't neccessarily be. (eg after a
crash you can find that a file has data in it that should be in
another file).

full journalling is much better for data integrity. (but slower).

above info culled from a recent l-k thread.
