>: DO YOU KNOW ANY WAY TO RECOVER THE CONTENT OF THE DUMP FILE ?

I have found good luck in simlar situation by
	- make an example of a non-corrupted structure
	- figure out the displacement of the good data in the file
	- lift a copy of the non-corrupted structure with dd into a file
		using the 'count=NNNN' argument of dd
	- place the good header, superblock, whatever onto the damaged disk
		using dd, possibly using the 'skip=NNNN' argument as well as
		the 'count=NNNN' argument.

Then its time to see if existing file access or repair programs can help.
