Detectamos los discos disponibles:

fsarchiver probe simple
fsarchiver probe -v
#[=====DEVICE=====] [==FILESYS==] [=====LABEL=====] [====SIZE====] [MAJ] [MIN]
#[/dev/sda1       ] [ntfs       ] [Windows-XP     ] [    25.00 GB] [  8] [  1]
#[/dev/sda5       ] [ntfs       ] [Data           ] [   120.00 GB] [  8] [  5]
#[/dev/sda6       ] [ntfs       ] [Backup         ] [    70.00 GB] [  8] [  6]

Accedemos a la partición correcta:

mkdir /mnt/win
# Para montar un disco sólo lectura:
ntfs-3g -o ro /dev/sdXN /mnt/win
# Para montar un disco lectura/escritura:
mount -t ntfs /dev/sdXN /mnt/win

Para copiar los datos podemos utilizar rsync:

rsync -ha --no-i-r --info=progress2 ruta/de/origen ruta/de/destino

Desmontamos los discos y finalizamos:

umount /mnt/win
shutdown -h now

Attach to a PC, run a recovery Ubuntu and use testdisk and photorec to restore files, even if partition is busted.

I recovered 200K pictures (25y of family stuff) for a customer recently.

EDIT: forgot to mention, before all the above, i used ddrescue to make an image from the disk (as it had corrupt sectors) and then i worked on the image (which was much faster too)
