Hey everyone, I would like to use two external drives with my MacBook Pro. One of them would be solely for Time Machine. The other one would be for backing up certain files (movies, photos, and music) so that I can share it between computers. I have two questions in this regard: 1) Which format should I use to be able to use on Windows and Mac 2) Is there a way to have certain folders automatically sync the way idisk does? For example, every day any changes that are made in my movies, photos, or music folder are auto-updated on the hard drive, or do I need to do this manually? Thanks for your help!
