You could try boot from the a cdrom if you have one, mount the drive
and then look around get more information.

I would try, from the the fixit system on the cdrom, trying to mount
different partitions to find out what partitions are mount-able.
You may then edit your /etc/fstab file (make a copy first). 
Once you have more information on the condition of the drives,
you'll be in a better position to post your next question, or just
fix it.
