Gparted resize failed, can't restore superblock

view story

http://askubuntu.com – I tried to resize my data partition with gparted, from a ubuntu 12.04 live usb. I then accidentally closed my laptop screen, which caused ubuntu to hibernate. After I tried to get it back up, the screen kept black and the hdd indicator didn't blink. I then rebooted (again to my live usb). Gparted shows now that the partition is of the desired size, but it can't detect the filesystem. I found out that the superblock went bad, and tried the instructions found here. After trying all superblock backups (16), I am still stuck. Can anyone help me with the next step? (HowTos)
