Your hard drive is lunched.  The fsck utility, not knowing that the hardware
is fried, is giving you false hope.

Revert to backups, or if you really need to, you can plug the HDD into
another machine (with lots of spare disk space), rip the contents of the
partition into a file, replace the blocks that can't be read with blocks of
NUL, and then try fscking and loop-mounting the resultant partition to copy
your data off.  Don't expect that method to necessarily recover all of your
data, though.
