I just purchased this internal 1TB drive yesterday, http://www.bestbuy.com/site/olspage.jsp?skuId=8909595&type=product&id=1213047091732 and installed it into my power mac G5 that's running tiger, not leopard quite yet. When I booted it up I got a pop up that said something like "drive installed is not compatible." ???? I know I installed this thing right and when I open up disk utility it recognizes the drive. I'm not sure what to do from there. Am I doing anything wrong? Do I seriously need to update to Leopard because of this? This is the first time I've ever installed an internal drive before so, I was under the impression that once booted it would just appear on my desktop as another drive that I could name. Am I wrong?
