Oh sorry, I missed that. But something like that must be expected on
every system on crashed at least if you do not mount the FS "in sync"
(like sugested for a totally safe qmail mailserver :-) ).

The journal normally only protects the filesystem metadata so that the
OS can still "recognize" the the block-dev as a filesystem. Some
filesystems also allow "data journaling" but at a cost of writing the
data twice to the disc(s).
