Antes de tudo, sinto muito pelo meu inglês.
Eu postei aqui porque eu pesquisei há muito tempo no google e não encontrei nada útil. Eu vi alguns posts neste fórum também, mas todos são muito antigos ou não resolvem nada.
Bem, meu problema é com um drive USB externo: Eu tenho um servidor Debian wheezy completamente atualizado com o kernel 3.2.0-4-686-pae, e comprei um drive USB para estender o armazenamento. O problema é quando eu começo a copiar muitos arquivos para armazenamento externo, então a unidade pára de funcionar. Eu vi que o drive continua montado, mas não responde e a única maneira de fazê-lo funcionar é desconectar o USB e, em seguida, reconectar novamente.
A unidade USB é uma mesa de trabalho Seagate Expansion de 2 TB e 3,5 "USB3.0 com fonte de alimentação externa.

Eu tentei mudar a porta USB, excluir a partição e reparticionar com fdisk novamente, EXT3 e EXT4 ... e não sei se há um problema no Linux ou talvez a unidade USB esteja com defeito.
Ontem consegui copiar cerca de 170GB sem problema, depois tentei copiar um arquivo de cerca de 68GB e ele começou a falhar.
Alguém sabe o que pode estar falhando ?. Eu quero saber antes de substituir a unidade com uma nova unidade e continuar com problemas.
Obrigado !!
