Eu tenho uma unidade de um ano que está me causando problemas. A cópia de dados para ele falha após cerca de 8 a 10 GB de transferências. Ele muda espontaneamente para "somente leitura". É devidamente formatado ext4, eu sou o dono. Pesquisando on-line, parece que isso é um sintoma de uma falha na unidade.
Como posso confirmar isso, pois os testes SMART indicam o contrário?
Eu fiz o óbvio como verificar o Utilitário de Disco e executei o teste SMART estendido. Todos os resultados do Utilitário de Disco são perfeitos. Taxa de erro de leitura e setores realocados estão mostrando zero.
Eu estou supondo que este disco é ruim e o SMART não o está detectando, embora eu não entenda o porquê. Eu gostaria de confirmar qual é o problema.
Não estou tendo problemas com os outros discos da máquina.

Por último, mas não menos importante, o screengrab de leitura / gravação, isso é novo. Ele costumava ficar bastante consistente durante a duração do teste.
EDIT- Quando eu liguei esta manhã a unidade tinha mudado de / dev / sda para / dev / sdc, estranho. Tenho certeza de que isso não aconteceu antes e tenho certeza de que foi / dev / sda. Eu troquei cabos SATA por um bom e conhecido e vi a mesma falha em cerca de 10 GB de transferência. Eu não mudei as portas SATA ainda, vou tentar isso em seguida. (Editar # 2, foi a porta SATA, alterando-o corrigiu o problema. Sinalizando isso como muito localizado.)
