I am looking to upgrade my Macbook Pro's Hardrive to at least 320gb. I am willing to do the labor myself as it does not seem that hard and does not require any fancy tools. I was wanting to get input on what the best option for me would be considering price and value. I do not have an external Hard drive so I would need a hard drive that can connect via USB. I have looked at the ones at MCE Technologies and those seem pretty good and inexpensive, but I wanted to know of my other options and to see if there is a cheaper route. Than You! Also, will I need a copy of Mac OSX Leopard when booting from my new Hardrive, even if I have transferred everything to the new Hardrive? Thanks!
