Unhappy Trying to repair a HDD and am getting this error message

e2fsck /dev/sda
e2fsck 1.42.13 (17-May-2015)
ext2fs_open2: Bad magic number in super-block
e2fsck: Superblock invalid, trying backup blocks...
e2fsck: Bad magic number in super-block while trying to open /dev/sda

The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
e2fsck -b 32768 <device>

How do I fix the super block, also, i am getting i/o errors when attempting to format the drive. the drive is a internal 320gb hdd.

One e2fscks a volume, not a drive. What does
e2fsck /dev/sda1
return? (or whatever partition you want to check).

/dev/sda1 could be a swap partition, so if what RandomTroll wrote returns another error, do e2fsck /dev/sda2. You can first run
fdisk -l /dev/sda
to see which partition is swap.

fsck does not fix hard drives, it attempts to fix filesystem errors. A filesystem is a higher, logical layer on top of a hard drive hardware device. If you're getting i/o errors, your drive might be broken and you may need to replace it. If you need to learn more about its status, I suggest looking into smartctl.

additionally, fsck should not be used on mounted filesystems.

Also, the filesystem is on a block device which could be a partition, like sda1, or it could be on a logical volume. lsblk will list all block devices.
