Superblock.. make my system unstable.

Yo, i tried a install in an old computer and superblock cause gnome to have serious issues and partition are almost broken..
i don't understand what to do with them..

Gparted before partioning : http://i.imgur.com/8L35M0A.png
Gparted when partionnated : http://i.imgur.com/y5RODDU.png

I get space used ,, when i clearly have nothing ..

I tried

dd if=/dev/zero of=/dev/sda

Not deleting the superblocks..

So i did  :

mke2fs -n /dev/sda

/dev/sda is entire device, not just one partition!
Proceed anyway? (y,n) y
Filesystem label=
OS type: Linux
Block size=4096 (log=2)

	102400000, 214990848

i did   :

e2fsck -b 32768 /dev/sda

e2fsck 1.42.8 (20-Jun-2013)
e2fsck: Bad magic number in super-block while trying to open /dev/sda

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
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>

I wanna remove them from backing up in my partion, or repair them..

Edit : i think, i posted in a wrong section, 1000 sorry.
