.Leia: A unidade ATA está falhando nos autotestes, mas o status de integridade SMART é 'PASSED'. O que está acontecendo?
Você pode tentar consertar seu setor ilegível, com
dd
ou com algum tipo de "utilitário de reparo". Faça backup de sua unidade primeiro!Com
smartctl
, não existe um comando simples que diga que está tudo bem...smartctl -H
é um falso amigo, não é confiável. Você tem que olhar para a saída completa.Mesmo que diga PASSOU, isso não significa nada, então apenas ignore e substitua a unidade com falha de qualquer maneira.
Em uma nota lateral, considere habilitar
Auto Offline Data Collection
e configurarsmartd
para executar autotestes periodicamente e enviar notificações por e-mail.Executar um autoteste uma vez a cada 6.354 horas não é muito confiável e, sem testes regulares, os erros do disco rígido não são detectados até que seja tarde demais para fazer algo a respeito.
