I've inserted a new HDD into my computer and now I am getting this error on one of the partitions on one of my other drives.
Error mounting: mount exited with exit code 1: helper failed with:
mount: wrong fs type, bad option, bad superblock on /dev/sdc2,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Doing "dmesg | tail" reported the following

If anybody has any ideas I would be grateful.
Isn't it the way that you figure out what is going wrong after you post for help. Anyway if anybody else come across this problem, this is how I fixed it:
I had accidentally swapped two sata data cables around on two drives and the one partition that was EXT3 rather then EXT4 couldn't handle it and blocked the mounting of the one at its mount point.
Doing "sudo gedit /etc/fstab" and then editing the sd letters (ie sdb1 became sdc1 etc) so they were correct for the drives as shown in the drive utility or Gparted fixed it.
