como entender o SMART linux ext4

como entender o SMART linux ext4

Inicialmente postei isso no fórum da comunidade openmediavault e nunca recebi resposta. Espero obter algumas dicas sobre SMART

Eu comprei esta unidadeAmazonastudo parecia funcionar bem, então comprei outro, então tenho dois exatamente do mesmo modelo, porém o primeiro começou a apresentar setores defeituosos. Eu sei que este é um assunto muito discutido e sinto muito por mais uma pessoa paranóica preocupada com seu Drive, mas as pessoas ficam paranóicas com seus drives e eu sou uma delas.

Eu configurei o smart em uma GUI do openmediavault e configurei algumas programações para uma vez por mês (aliás, tudo bem ou o que é recomendado para agendamento inteligente). O segundo disco rígido que encomendei está funcionando bem, assim como o SSD que executa o sistema operacional OMV.

Assim que recebi meu primeiro e-mail do smart dizendo que eu tinha 24 setores atualmente ilegíveis (pendentes), fiquei preocupado. Eu li muito e entendi se estou certo, está esperando para ler esses setores e remover os dados que podem substitua e deixe o setor defeituoso de lado. Posso estar muito errado. Este é meu e-mail diário Captura de tela do e-mail que recebi Recebi este uma vez após uma reinicialização.2 setores off-line incorrigíveis Alguém poderia me explicar Reallocated_Sector_Ct?Capturas de tela dos atributos de informações SMARTMais uma pergunta restante e vitalícia?Registros de autoteste Essa é a minha informação se eu fizer smartctl -x.Qualquer ajuda ou insight seria muito apreciado.
