Parece que você pode ter algum firmware da unidade com bugs ou uma unidade com defeito. Não faria mal rodar o longo autoteste SMART. Você pode usar o smartctl ou o utilitário de disco gui para fazer isso. Você também pode baixar e executar a ferramenta de diagnóstico de unidade da Seagate. Se houver problemas com a unidade, eles devem substituí-la na garantia.
Eu diria que os erros de busca e leitura crua não são críticos, talvez apenas irritantes. Não há nada que você possa fazer a não ser substituir a unidade.
Para mais informações e explicações sobre os dados da SMART, consulte a Wikipedia .
Se os erros começaram a aparecer depois de uma atualização do kernel, pode valer a pena iniciar em um kernel mais antigo e verificar os logs lá.
