I just ordered a Samsung 320GB 5400RPM drive for my MacBook to replace the original 160GB hard drive. I also got a free USB external enclosure for the Samsung drive when I purchased it. I was just wondering if there is a program that will allow me to just copy whats on my 160GB hard drive to my 320GB one exactly so I can just take the 320GB drive out of the enclosure and pop it into my MacBook and have it ready to go?
