Hello, Could someone please tell me how to format all of my drives like a two year old. LOL There are so many options, etc that it's a little confusing. I have a new MacPro and I just received the drives below. The MacPro came with a 640 WD blue drive. This is how I want to install my drives but I don't know how. Sled 1: WD 640 Black #1 I want to use this one as my main Mac OS boot drive. All of my mac apps including the os will be installed here. I hear some people say that it is best to have the OS on the outer part of the disk for fast access. How do you do this? Do I need to partition it, and if so, how big? Where are my apps going to go, on the other partition of this drive? Sled 2: Apple 640 This is the drive that came with my macpro and it currently has the Mac OS and everything else installed by Apple on it. I want to use this drive for Time Machine backups and for SuperDuper backups, both. How should I format this drive? Sled 3: WD 640 Black #2: I want to use this drive to install Vista Home Premium 32bit. Sled 4: WD 1 TB Black: I want to use this drive for ripped DVD's. I will most likely use DVD Fab (Windows program installed on Sled 3 above) to rip them directly to this drive. I was wondering, though, will this drive be accessible to the Mac? Meaning, can I play movies with the mac from this drive, or will I only be able to play them with windows? Thank you for your help.
