So I have 160 gb mbp shows up as 149, and I have two 320 GB externals. Now I want to use Windows XP, Leopard, Tiger, and Logic. How should I partition each drive to have enough space for everything? I will be using Leopard mostly then Tiger for Logic/Protools and Windows for gaming. I figured I'd keep the internal hard drive just for Leopard and the installion of XP. Logic is around 50 GB in itself. and Pro-Tools is a couple gbs, maybe 2 or something. How can I partition everything to where I have enough space for all my backups, my projects and everything, without everything getting too confusing? Thanks for the help.
