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/sdd1 /media/Jääns -o force Or add the option to the relevant row in the /etc/fstab file: /dev/sdd1 /media/Jääns ntfs-3g defaults,force 0 0
