Well, if only the first 500 sectors or so are gone, you still 
have backup superblocks left. For example:

bohr:/home/anthony# mke2fs -F -n /dev/sda1
mke2fs 1.27 (8-Mar-2002)
... snip ...
Superblock backups stored on blocks:
        32768, 98304, 163840, 229376, 294912, 819200, 884736

If you don't have any superblocks left, read about the -S 
option, which can give you new ones.

Any fsck on a file system where the primary superblock was 
destroyed would (I think) error out.

Also, there is e2recover which might help, too.
