Okay, I have a smaller (100gb) external pretty much full of movies and tv shows. I also have a PS3 that I want to put some of the movies on there, namely some of the blu ray's i have downloaded.

I plug my external in and it doesnt work.

I read up on it and all i hear is partition (which i am still confused about, dont want to lose the stuff i have on my external), FAT32 etc...

yet, I am still confused.

I do not want to lose the stuff I already have on my external and I do not have space on my new macbook to put all 100gb on there to fool around reformating my external hard drive.

anyone know what I can do?
