I tried to add a second hard drive, but was unable to do so. I edited /etc/fstab with pico to do this. Now i cannot boot the 1st hard drive by itself. It comes up with a superblock eroor. when i Pico the etc/fstab file i cannot save the resultant edit as the fille is read only. Basically i woul;d like to boot the 1st drive up and then back the drive up and restore it to the 2nd disk after installing a new verion of esmith. HELP
