Read / Write NTFS External Hard Disk In Mac Mountain Lion

I have a 1TB external hard disk which is NTFS formatted and I have some files in that hard disk. When I try to use it in my Mac (Mountain Lion), I get this error:

I try to use Paragon, NTFS 3G, SL-NTFS but did not show any success and my hard disk still unmounted.

1. How do I solved this issue?


2. After installing the Paragon, NTFS 3G, SL-NTFS (or any other apps), should I do anything else?


3. OR, perhaps this issue comes from my external hard disk itself?

Note: This external hard disk is well readable and writeable in Windows OS.
