[root@nas] ~# mount -t ntfs /dev/da1 /media/
Failed to startup volume: Invalid argument.
Failed to mount '/dev/da1': Invalid argument.
The device '/dev/da1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?
Mount failed.
