I have a 2011 MBP running Lion, and I ordered a Seagate Momentus XT 750 GB Hybrid drive from Amazon, which should be here later this week. I'm excited to add quite a bit of space in comparison to my 320 GB, and also the speed boost. My question is, what is the easiest method to do this? I have an unused 2 TB external hard drive, which I am assuming I can use with Time Machine. I'd like to ideally copy everything from this hard drive so that I can essentially have a carbon copy of this drive, plus all the excess space, if that's possible. I have WiFi available as well, if that helps with the whole Lion recovery, but I wanted to come to the experts first. Edit: Thanks everyone, ten minutes after getting home from work today I am now running with the new hard drive installed, cheers!
