Após esses erros, o sistema de arquivos fica somente para leitura e nada funciona corretamente depois disso. Eu não posso nem reiniciar as vezes. Eu tentei remontar o sistema de arquivos, mas isso não funciona. Somente a reinicialização consertou (temporariamente).
Depois de examinar os registros, descobri que isso pode ajudar:

Eu tentei o seguinte:
fsck -M -fy /dev/sdb1
de um USB ao vivo de 14.10 parecia estar bem. Qualquer ideia / ajuda seria muito apreciada.
