Need Help Formatting Harddrive

[irubes]

This question has a few parts.

Summary:

1. I have a 2 TB Western Digital Hard drive that I use on my macbook.
2. The harddrive has 300 GB used right now with videos and music.
3. I have a PS3 and want to be able to plug this HD into the PS3 and watch the videos on my tv and listen to my music through the tv.

Question: Is it possible to reformat my harddrive to Fat32 (which I understand is the required format for PS3 to read it and for my macbook to read it) without erasing everything? Can i partition just a single chunk of the harddrive to fat32 and just put what i want to watch on tv in that part without deleting the rest of it? Or do I need to back up the entire harddrive, reformat it to Fat32, and then it'll work?

I also require instructions on how to reformat the harddrive in either case.

Any help is appreciated!
