       -S     Write superblock and group descriptors only.  This is useful
if
              all  of the superblock and backup superblocks are corrupted,
and
              a last-ditch recovery method is desired.  It  causes  mke2fs
to
              reinitialize  the  superblock  and  group descriptors, while
not
              touching the inode table and the block and inode  bitmaps.
The
              e2fsck  program  should  be run immediately after this option
is
              used, and there is no guarantee that any data will  be
salvage=E2
              able.   It  is critical to specify the correct filesystem
block=E2
              size when using this option, or there is no chance of
recovery.


Apologies if you've already been down this route with no sucess. :(
