Disco rígido criptografado parou de montar

Question

Há algum tempo adicionei um disco rígido de 4 TB ao meu computador criptografado. A unidade é criptografada e configurada para ser montada automaticamente na inicialização. Isso funcionou muito bem e dandy por um tempo, então de repente eu recebi essa mensagem um dia.
