I believe most of the Mac user know by default Mac OS only can read from Windows-formatted NTFS drives. To write NTFS disk, you need to have 3rd party software.
When you google it, first page of google sure will show you the two best paid version of NTFS app which is Paragon NTFS for Mac and Tuxera.
If you look for free version of NTFS app, i would recommend an application called Mounty for NTFS which available for free. You can get it here right now. I have tested this apps, it is easy to use and the performance not bad.
If you have any others good free apps, please do not hesitate to share with me. 🙂
