Eu tenho um Dell XPS 15 9550 . Eu tenho executado o Ubuntu 16.10 nele por quatro meses sem dramas.
Dois dias atrás, atualizei para o Ubuntu 17.04 . Cerca de uma hora após a atualização, meu disco rígido remontou ao modo somente leitura. Quando eu pulei para uma tela tty, apareceu:

Veja o que o fdisk -l

Eu reiniciei e continuei a receber o erro uma vez por hora. Então eu reinstalei o Ubuntu 17.04 do zero . No entanto, ainda estou recebendo o mesmo problema.
Eu tentei executar o fsck criando um arquivo / forcefsck (criei um script de shell de wrapper que adiciona o sinalizador -v
e gera stdout em um arquivo). Aqui está o resultado:
fsck.fat 4.0 (2016-05-06)

Eu tentei inicializar de um USB ao vivo e rodando e2fsck -p /dev/nvme0n1p7
como sugerido aqui ( link ). Não deu nenhum erro.
Eu também tentei executar smartctl -t long /dev/nvme0n1p7
, mas os resultados parecem indicar que a ferramenta não funciona com meu SSD específico:

Alguma ideia de por que esse problema pode estar ocorrendo e como posso resolvê-lo? Obrigado! :)
