Can not mount internal driver in Archbang 2014

Question

I have just installed archbang 2014 on my laptop Asus K53SV. I followed the instruction on Archbang wiki. I have already installed ntfs-3g, but I can not access to the internal (ntfs-formatted) devices. The computer said that : udevil: denied 88: device /dev/sda5 is an internal device and you're not root I have already install udevil also.

What is my problem? I heard that may be the etc/fstab is wrong, and here is mine:

#
# /etc/fstab: static file system information
#
# <file system> <dir>   <type>  <options>       <dump>  <pass>
UUID=9120f084-24b3-4047-b082-58a720a73433 / ext4 defaults 0 1

Here is the result after running lsblk -f

Please help me. Thanks.
