Hi guys. I just bought a 250gb Maxtor 7,200rpm 8mb cache internal hard drive. I also bought an external case, to make it an external hard drive. It has 2 firewire ports, and I want to partition it to have 150gb for my Mac, and 100gb for my PC. I have absolutely no idea what so ever, of how to go about doing that. Can you please send me a step by step guide to do this? Thanks Eibbor B.T.W I am using WindowsXP and Mac OS 10.2.8.
