Hi, Can you please help me as I am having and have had so many problems its easier just to get to the point and tell you the mess I am in now. Have Macbook pro, bought second hand. Put "new" hard drive in that had been formatted on a windows machine with macdrive 8 in the MAC OS EXTENDED (hsf+) format. Old hard drive is not accessible at all. Do I need to do anything else to the hard disk to enable the system to "see it" or does this happen when I boot from my OS DVD/CD which will be Snow Leopard, (I am yet to buy it) Please help me if you can because I am not ashamed to say that I have no idea, even after reading through forums and googling for two days.
