É possível desbloquear um SSD bloqueado (não criptografado até onde eu saiba) sem saber a senha?
Eu já tentei desbloqueá-lo com hdparm
no linux com a senha mestra padrão do disco que encontrei on-line (32 vezes 't'). Também tentei várias ferramentas como blancco
para apagá-lo sem sucesso. O SSD é um Samsung pm871
que é arrancado de um laptop.
Eu realmente não ligo para os dados, só quero que o SSD funcione normalmente. Alguém tem uma idéia do que eu poderia tentar ou pelo menos me dizer que não é possível?
Veja o que hdparm -I /dev/sda
retorna
