The first thing you should know is that OS X cannot write to ntfs drives, it can read them though. What I have done in the past is put a friend's HD inan external case so I could back up his files. So either put the drive in a case or directly into your mac.
I am not sure how the reverse works, but I am sure someone else here does.
What exactly are your goals in doing this by the way? That should help the people here narrow their answers.
