Quando eu uso um pendrive com o Ubuntu, ele às vezes se desconecta. Eu olhei no syslog e encontrei I/O error, dev sdb, sector 31159048 , então suponho que seja um setor ruim. Como posso consertar isso?
Aqui está um registro completo do que acontece:

Se é um setor ruim, a única maneira de consertá-lo é obter um novo pen drive. Também é possível que o conector da unidade esteja danificado e, nesse caso, você também precisará de uma nova unidade. Uma terceira possibilidade é que a porta do seu computador está ruim, você tentou outra porta? Se estiver quebrado em uma porta, essa porta está quebrada. Se a unidade estiver quebrada em mais de um PC, a unidade está quebrada.
