$ mount -t ntfs-3g /dev/md0 /mnt/array_0
NTFS signature is missing.
Failed to mount '/dev/md0': Argomento non valido
The device '/dev/md0' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
