Recentemente, tive alguns problemas ao copiar dados grandes (geralmente > 2 GB) do disco rígido principal para outro, montados em / media. Tentei ler alguns tópicos, mas não consegui encontrar uma resposta. Ambos os sistemas de arquivos são formatados em EXT4 e eu não acho que meu disco tenha problemas, porque eu mudei recentemente tentando encontrar uma solução. Em particular, o processo de cópia pára, o sistema de arquivos é remontado automaticamente como somente leitura e eu recebo uma mensagem "Arquivo de emenda de erro: entrada / saída".
Meu computador está executando o Ubuntu 16.04.4; Eu anexei o dmesg -H output para maiores informações. Peça-me todas as informações de que você precisa. Obrigado antecipadamente por todos.
