Eu instalei o Ubuntu 14.04 e estou recebendo apenas o sistema de arquivos de leitura (/ dev / sda3) aleatoriamente. Anteriormente eu estava usando o Arch linux (3,14 lts), que tinha o mesmo problema, mas descartado devido a outros problemas. Eu testei a partição com badblocks (teste somente leitura), mas não recebi nenhum erro. Aqui está a saída do dmesg depois que recebi o erro

Na verdade, não havia badblocks em sda3, mas eu encontrei muitos em sda2. Todas as minhas coisas estavam em sda2. Então este comportamento somente leitura estava surgindo apenas quando eu estava usando o sda2 como ouvir música, trabalhar em um projeto, etc. Ler esses badblocks em sda2 estava causando o remoting de sda2 como um sistema de arquivos somente leitura.
Posso dizer ao fsck para não ler esses badblocks em sda2 (ele é formatado em NTFS porque tenho inicialização dupla)?
Parece que você tem um problema de hardware. Se esta é uma unidade sata, você poderia substituir o cabo sata, ou pelo menos verificar os conectores etc ... Caso contrário, você poderia atualizar a questão com a saída fdisk -l.
