So i have a 17" MBP and i have the OEM 160G hard drive, its dam near maxed out. I upgraded to Leopard but don't know where the disc is. So i am wondering if there is a way I can connect my MBP to an external HD. Carry over all the data to the external. Removed the old HD, install the new HD and plug in the external and boot the comp of the external drive and then swap over the data..... Is this possible?
