Can't rebuild journal of EXT-3 partition

[Longming Lee]

Dear friends,

There is a EXT-3 partion in the FC2 hard disk, and it needs to
fsck for something wrong. I do the fsck while booting. But
6 hours passes and it can't be done. I stop fsck and then I
mount it to be EXT-2 OK.

I unmount this broken partition, and try to rebuild the journal of EXT-3,
but it is failure.

[root at nfs2 root]# tune2fs -O ^has_journal /dev/sdb1
tune2fs 1.35 (28-Feb-2004)
Illegal block number passed to ext2fs_unmark_block_bitmap #1632133966
for block bitmap for /dev/sdb1
Segmentation fault

How should I do to fix or rebuild the journal of this EXT-3 broken
partition?

regards,
