Answer 1

Você tem um super bloco quebrado: Unable to read the contents of this file system!

Verifique seu sistema de arquivos:

sudo fsck.ext4 -v /dev/sdaX

Se o seu sistema de arquivos estiver corrompido, você deve ter uma saída como esta: The superblock could not be read....

Execute o comando mke2fs para descobrir os backups de superblocos:

sudo mke2fs -n /dev/sdaX

Restaure o superbloco perdido por meio do comando e2fsck :

Você deve usar o primeiro superbloco obtido de mke2fs

sudo e2fsck -b put_the_first_block_number_here /dev/sdaX

Reinicialize seu sistema e execute gparted
