meu hdd externo, foi corrompido ou danificado, não sei qual deles e estou tentando consertar ou pelo menos obter alguns dados dele. (dano ao sistema do disco rígido já aconteceu uma vez, mas foi facilmente resolvido apenas fazendo o login no linux e conectando o dispositivo, eu estou esperando por algo parecido agora, embora o HDD seja bem antigo, o que significa que pode ser uma falha de hardware, mas Algumas semanas atrás, o HDD sempre mostrava "Format disk ..." quando conectado ao Windows, mas pelo menos mostrava algo - agora ele não aparece no Windows e não consigo encontrá-lo no Linux qualquer um.
Eu tentei executar o comando fdisk -l :

Ele não aparece no fdisk e não reconhece o usb após o dmesg . Eu não sou realmente especialista em Linux ou sei muito sobre as informações que esses comandos imprimem, portanto, estou procurando sugestões sobre o que tentar em seguida para trazer o HDD de volta dos mortos. (O plano inicial estava apenas executando o "testdisk" no disco rígido, mas também não é reconhecido na lista de dispositivos do disco de teste.
