Actuall, e2fsck can also do the journal replay, so depending on whether this
is the root fs or not, it may be that you get a journal replay and still
mount it as ext2...

Well, if you had a SCSI error, then it may be that the fs marked an error
in the superblock, which would force a full fsck also.

Note also, that it is often normal to have "orphaned inodes" cleaned up when
the journal is cleaned up. This is not an error. I normally have these on
my system because of PCMCIA cardmgr creating device inodes in /tmp and then
unlinking them immediately after opening them.

If you have an open but unlinked file, then ext3 will delete this file at
mount/fsck time (unlike reiserfs which leaves it around wasting space).
Did you actually get files in lost+found, or only the orphaned inode
