Monter Volume DD ext. ntfs-3g

Salut à tous,

Je voudrais mettre le DD externe d'un copain sur mon Ubuntu 7.10
quand je le connecte, j'ai le message suivant:

Impossible de monter le volume "Disque dur"
$LogFile indicates unclean shutdown (0,0) Failed to mount '/
dev/sdf1': Opération non supporté Mount is denied
because NTFS is maked to be in use. Choose one action:
Choice 1: If you have windows then disconnect the external devices by clicking on the "Safely Remove Hardware"
icon in the Windows taskbar then shutdown Windows
cleany. Choice 2: If you don't have Windows then you can use
use the "force" option for your own responsibility. For
example type on the command line: mount -t ntfs-3g/dev/sdf1/media/Disque dur -o force
Or add the option to the relevant row in the /etc/fstab file:
/dev/sdf1/media/Disque dur ntfs-3g defaults,force 0 0

J'ai pas de windows installé, je suis débutant sous linux et quand je tape la premiere option dans un terminal
il me répond:

Usage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .

Et pour la deuxieme option, je ne sais pas comment faire pour modifier "fstad"

Merci
