I'll be setting up my Mac Pro tomorrow and it has 3 Hard Drives.. I plan to have it set up like this HD1 (SSD): Boot/Applications HD2 (1TB): Data/Music HD3 (640GB): Scratch Disk Partition or full HD for Scratch Disk? If HD3's Scratch Disk is fine as a partition, I'll partition it 3 times for a Windows Operatin System, Time Machine, and a Scratch Disk.. is there a problem with using this drive like this for the scratch disk? Another thing is I'm thinking about installing Windows XP as a Virtual OS.. If I do this what would be the best way to do it? I've read about kernal panics and other kinds of problems so I decided to stay away from trying it but i might need to for a couple programs.. is there any safe options or a way I can install something like that so it doesnt effect the Boot drive if something goes wrong? Is there a better way to set this up? How should all the drives be formatted b4 I use them?
