Como posso recuperar minha partição de disco rígido corrompida?
Eu posso tentar recuperar essa partição usando o GParted, mas o GParted vê uma mensagem de erro
GParted 0.25.0 --enable-libparted-dmraid --enable-online-resize

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
or e2fsck -b 32768

========================================
E eu tentei esses comandos
sudo mke2fs -n /dev/sda12 mke2fs 1.43.4 (31-Jan-2017) /dev/sda12
Este comando retorna

Esta partição contém meus dados importantes.
Eu também posso tentar encontrar partições
sudo fdisk -l
Mas este comando retorna um erro para

Partition 4 does not start on physical sector boundary.
Partition 5 does not start on physical sector boundary.
Partition 6 does not start on physical sector boundary.
Partition table entries are not in disk order.
