Thanks Helmut, that pointed me in the right direction.

    for drv in $ext2drives; do
        echo; echo "Checking filesystem on drive $drv."
        fsck.ext2 -p -C - $drv:
        r=$?
        if [ $r -ge 2 ]; then
            echo
            echo "Warning: e2fsck FAILED ($r)"
            echo "         Starting single user shell. Fix the"
            echo "         filesystem on drive $drv by running fsck.ext2"
            echo "         and REBOOT!"
            echo
            sh -si < /dev/console > /dev/console 2>&1
        fi
    done

This returns an error 8 when the partition doesn't exist.
