Partition damaged

["Patricio Inzaghi" <patricio.inzaghi@gmail.com>]

Hello there,

I have a headache with my hard disk, i used gparted to resize a
partition and for some strange reason it make it unusable. I make an
image of the device with ddrescue. When i try to mount it ("mount
bkp.img /media/data -o loop") , it claims:

EXT3-fs error (device loop0): ext3_check_descriptors: Block bitmap for
group 1 not in group (block 0)!
EXT3-fs: group descriptors corrupted!

If i use "fsck -y bkp.img" , only shows the program usage options and
nothing more.

When i use "fsck.ext3" (it was an ext3 partition), the error message vary to:

fsck.ext3: Group descriptors look bad... trying backup blocks...
fsck.ext3: Bad magic number in super-block while trying to open bkp.img

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

And finally, if i execute "e2fsck -b 8193 bkp.img", show the same message error.

Is there any possibility of restore the partition? or i have to focus
in data recovering?

Thanks in advance, and sorry for my English.

Cheers
