i bought a second HD for my powermac. I finally got it working. now i want to Stripe Raid the two together to make one large drive. but to do that i have to take off all the info thats already on my computer. To make my life a little easier, and to not have to reinstall everything. I want to know if i can install os x on an external drive and move everything over as if its another computer. Is that possible. if so how?
