I currently have a 320 GB external hdd (not big enough, I know). As of now, it has two NTFS partitions (both of which only have about 50 GB of space left on them). In preparation of my upcoming purchase of a MBP I'd like to organize and repartition this external drive which will be used for backing up. As soon as I get my MBP I'll be partitioning the internal drive with boot camp so I'll have three partitions: 1. OS X (main partition) 2. Windows XP (smaller, around 30 GB, mainly for gaming and a few applications) 3. FAT 32 (to be able to share documents between them) So, ideally what I think I'd like to do is to have three partitions for this external drive: 1. OS X (what does OS X use to backup?) - I'll be backing up the MBP to this periodically. 2. Media Backup (How would I set this up to be able to say put all my music and movies on the hdd from my windows pc and then move them onto my MBP?) - I'd like to keep a copy of all my music, movies, pictures, etc. on this drive. 3. Windows XP (NTFS) - I'd also like to keep a copy of my Windows stuff on this drive so I don't have to put it all onto the bootcamp partition. So, long story short, how do I accomplish this?
