I had earlier mentioned about the correct way of mounting NTFS partition using ntfs-config. However, recently I experienced a few crash errors and thus found this method easier to use.
Open Unity (using windows key) and type "Startup Applications"
Then click on the Add button, Write a name for this operation such as "Mount ntfs drives", then in command input box, write
udisks --mount /dev/sda2, to automount the ntfs partition.
Note: You need to replace the /dev/sda2 with your actual NTFS partition number.
You can get this number by
Below is the output of this command in my computer.
Since I had to mount the partition with the label "Storage", I entered this command:
udisks --mount /dev/sda4
This auto mounts the partition on start-up with correct user permissions.
