If you have noticed, Mac OS X doesn’t support writing onto NTFS disks. But not to worry, you don’t have to install any third party drivers to enable this. Mountain Lion 10.8.3 already has native write support for the NTFS. OSX Mountain Lion does have built-in support for NTFS, and it can read and write. However, Apple does not enable it by default.  

Here is what you should do:

Uninstall other 3rd-party NTFS software, like Paragon, Tuxera or NTFS-3G.
Edit /etc/fstab (you can do this with “sudo vi /etc/fstab”)
Add the following line:
LABEL=”VOLUME_NAME_WITHOUT_QUOTES” none ntfs rw,auto,nobrowse
Quit your editor
Now, just unmount and re-mount the disk
