Restaurar unidade USB corrompida

Question

Recebo erro de leitura / gravação ao tentar criar uma nova tabela de particionamento em uma unidade USB.

sudo mkfs.ext4 /dev/sdc
mke2fs 1.43.9 (8-Feb-2018)
Warning: could not erase sector 2: Input/output error
Creating filesystem with 31258624 4k blocks and 7815168 inodes
Filesystem UUID: 8eac3af0-c5a7-4f09-ba50-8938c382058e
Superblock backups stored on blocks: 
        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 
        4096000, 7962624, 11239424, 20480000, 23887872

Allocating group tables: done

Creating journal (131072 blocks): done
Writing superblocks and filesystem accounting information:   0/954

Ele empaca depois disso. Alguma idéia?

Eu também tentei:

sudo dd if=/dev/zero of=/dev/sdc status=progress
dd: writing to '/dev/sdc': Input/output error
1+0 records in
0+0 records out
0 bytes copied, 0.00130756 s, 0.0 kB/s

bem como

sudo e2fsck -f /dev/sdc           
e2fsck 1.43.9 (8-Feb-2018)
e2fsck: Input/output error while trying to open /dev/sdc

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>
 or
    e2fsck -b 32768 <device>

bem como

sudo mke2fs -n /dev/sdc
mke2fs 1.43.9 (8-Feb-2018)

        4096000, 7962624, 11239424, 20480000, 23887872

Eu tentei o sudo e2fsck -b xxxx, onde xxxx é um bloco listado acima, mas retorna a mesma saída o tempo todo:

e2fsck 1.43.9 (8-Feb-2018)
e2fsck: Input/output error while trying to open /dev/sdc

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>
 or
    e2fsck -b 32768 <device>

Não preciso restaurar nenhum dado dessa unidade, mas quero torná-lo utilizável novamente. Qualquer sugestão seria muito apreciada.

use o mkfs para formatar partições use fdisk ou parted para criar partições e partições
