So I now have two 640Gb WD in Raid 0 with OSX installed on them and I have 2 74Gb Raptors in Raid 0 that I'm trying to install Vista on via boot camp. However as soon as I open up the boot camp assistant and click continue I get this message You cannot partition an external disk drive. Restart your computer using your computer's internal startup disk. What's causing this and is there a fix?? Thanks in advance. Please I need help fast trying to get my game on tonight and this is holding me up.
