Primero que nada, lo siento por mi inglés.
Publico aquí porque he buscado mucho en Google y no encontré nada útil. También he visto algunas publicaciones en este foro, pero todas son demasiado antiguas o no resuelven nada.
Bueno, mi problema es con una unidad USB externa: tengo un servidor Debian wheezy completamente actualizado con el kernel 3.2.0-4-686-pae y compré una unidad USB para ampliar su almacenamiento. El problema es que cuando empiezo a copiar muchos archivos al almacenamiento externo, la unidad deja de funcionar. He visto que la unidad continúa montada pero deja de responder y la única forma de hacerla funcionar es desconectar el USB y luego volver a conectarla.
La unidad USB es una Seagate Expansion Desktop 2TB 3.5" USB3.0 con fuente de alimentación externa.

Jul 18 10:57:41 SomeServer kernel: [163446.952110] usb 1-2: new high-speed USB device number 13 using ehci_hcd
Intenté cambiar el puerto USB, eliminar la partición y volver a particionar con fdisk, formato EXT3 y EXT4... y no sé si es un problema de Linux o tal vez la unidad USB está defectuosa.
Ayer pude copiar unos 170 GB sin problema, luego intenté copiar un archivo de unos 68 GB y empezó a fallar.
Alguien sabe que puede estar fallando?. Quiero saberlo antes de reemplazar la unidad por una nueva y seguir teniendo problemas.
¡¡Gracias!!
Respuesta1
" Buffer I/O error" Desafortunadamente, en la mayoría de los casos, cuando sucedió fue una falla de hardware. Para reducir el problema, puede intentar iniciar con Live CD/USB.
ACTUALIZAR:
Puedes intentar tratar esta unidad con Gpartedy/o fdisk.separadotambién tiene el suyoCD en vivo
