Failed to mount '/dev/sdb1': Opération non supportée
Mount is denied because NTFS is marked 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 cleanly.
Choice 2: If you don't have Windows then you can use the 'force' option for
your own responsibility. For example type on the command line:
mount -t ntfs-3g /dev/sdb1 /mnt/disk -o force
Or add the option to the relevant row in the /etc/fstab file:
/dev/sdb1 /mnt/disk ntfs-3g defaults,force 0 0
