Hey guys. Just did a hard drive upgrade on my macbook pro core duo 2.0. Purchased a 200gb hitachi, the drive works great!!! My question is, is it possible to use the hard drive i pulled from the MBP, slide it into an external USB2.0 enclosure, and boot into the OS thats on it. The reason being because i need to back up some important data to my .mac that is still on that drive. Thanks for helping in advance!!
