Hey, so im kinda still new to mac, i bought an Alu. Macbook and im thinking of upgrading the 160 stock harddrive with a 7200.3 seagate soon. I'm just wondering how i can back up everything to the hard drive coz i have no external drive right now. I will buy an enclosure for the 160GB drive if that helps me. Also, i only want to back up the mac portion and i will just do a clean bootcamp setup when i install the new drive. Anyone can help me? thanks
