Hola Nico, 

Pues yo intentaría correr fsck como lo indica el mensaje que te arroja el error, creo que seria algo así:

fsck /dev/hda (o sda)


bueno, quiero hacer eso. pero primero tengo que desmontar la particion (sda3). cuando lo intento dice que esta ocupada:

ubuntu en ubuntu:~$ sudo umount -a /dev/sda3
umount: /var/run: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
umount: /tmp: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
umount: /dev/shm: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
umount: /rofs: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
umount: /cdrom: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
umount: /dev: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
umount: /: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))


y ya no puedo seguir. probe desbloquearla con el siguiente comando:

ubuntu en ubuntu:~$ fuser -m -k /dev/sda3

ese comando no tira ningun error ni nada. pero cuando quiero desmontarla con el otro  comando sigue igual...
