That is better in any case; such stale additional signatures cause

OK, the normal way to fix the "differences between boot sector and its
backup" problem on a vfat filesystem is:
fsck.vfat -ar /dev/hda1
(The filesystem should be unmounted for this procedure.)
However, I have never had to use it on an ext3 partition and I have no
idea if is safe, therefore I am hesitant to recommend it to you.
(Fsck.vfat will overwrite the backup of the boot sector with its current
content, making the two identical again.)
I would like to see your output of
wipefs /dev/hda1
(to verify that the ext3 signature has the normal offset) and also the
output of
fdisk -l /dev/hda
to check if the partition type is correct.
