mount: debe especificar el tipo de sistema de ficheros
lbressan@lbressan:~$ sudo mount /dev/sda /mnt/discoloco -t ntfs-3g
NTFS signature is missing.
Failed to startup volume: Argumento inválido
Failed to mount '/dev/sda': Argumento inválido
The device '/dev/sda' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
lbressan@lbressan:~$ mount /dev/sda1 /mnt/discoloco -t ntfs-3g
mount: sólo el usuario root puede efectuar esta acción
lbressan@lbressan:~$ sudo mount /dev/sda1 /mnt/discoloco -t ntfs-3g
$LogFile indicates unclean shutdown (0, 1)
Failed to mount '/dev/sda1': Operación no soportada
Mount is denied because NTFS logfile is unclean. Choose one action:
   Boot Windows and shutdown it cleanly, or if you have a removable
   device then click the 'Safely Remove Hardware' icon in the Windows
   taskbar notification area before disconnecting it.
Or
   Run ntfsfix version 1.13.1 on Linux unless you have Vista.
Or
   Mount the NTFS volume with the 'ro' option in read-only mode.
