Grub Error 17, possible bad grub sector

I have a single boot SUSE (11.4, I believe) system with a single hard drive. I have made no changes to the system in a couple of years. When I rebooted the system a few days ago I got a grub error 17. After searching some forums, I was able to get the system started with a SUSE LiveCD. I ran an fdisk -l and findgrub:

I'm concerned that I'm getting the 0x83 (INVALID) when findgrub looks at /dev/sda6. I haven't been able to mount /dev/sda6, I receive an error that it is the incorrect fs type or has a bad superblock. fsck on /dev/sda6 aborts because of a suspected harware problem.

Any help on being able to correct the MBR or mount this drive to copy the data to another drive would be very much appreciated.
