Most journaling filesystems make guarantees on the filesystem meta-data, but not on the data. Some like ext3, and reiserfs (with suse's journaling patch) can journal the data, or order things so that the data is written before any pointers (ie meta-data) make it to the disk so it will be harder to loose data.
