Answer



You have a broken super-block :Unable to read the contents of this file system!


Check your filesystem:


sudo fsck.ext4 -v /dev/sdaX

If your filesystem is corrupted , you should have an output like this :The superblock could not be read....


Run mke2fs command to find out the superblock backups:


sudo mke2fs -n /dev/sdaX

Restore the missing superblock through the e2fsck command:


You should use the first superblock obtained from mke2fs


sudo e2fsck -b put_the_first_block_number_here /dev/sdaX

Reboot your system then run gparted
