Best file system for PPC Mac, Intel Mac, and Win 7 PC
I really was nut sure which section to post this in, so this seemed like the best place. I have a 3TB external hard drive, that I need to read and write to on a G5 running 10.5.8, A MacBook Pro running 10.8.2, and various windows PC's, what is the best file system to use, or better yet, format, depending on what terminology you use, adn I need to transfer large files(larger than the 4GB limit on FAT). Im willing to try any suggestions. I would prefer not to use extra software, if it is neccessary though, I can on the mac's but not as easily on the Win PC's. I would also prefer an app from apple, I seem to have bad luck with third-party software, but if you know of one that works nicely, again, I'm willing to try any suggestions.
