Estou executando um novo WD Black 3TB. É formatado como sistema de arquivos ext4 e usado com o cartão Banana Pi. Na verdade, estou tendo duas configurações desse tipo, mas apenas uma me causa problemas.
O segundo Pi faz um backup do primeiro Pi através da rede, e em alguns momentos não especificados o seguinte item aparece nos logs (colados abaixo), o HDD remonta como somente leitura.
O que pode ser? Verifiquei que o disco não está superaquecido.

o status do meu disco inteligente parece limpo:

Eu terei o cuidado de desligar o disco quando não estiver ativo .... A única atividade que o disco faz é fazer backup por 10 minutos todas as noites. Não foi escrito nem uma vez.
