I have a 13" MacBook, and I'm swapping out the factory-installed 120 GB hard drive for a 320 GB one. I have been using it with the 120 GB disk, and I want to make a copy of it on the larger disk before I swap them. I have a fairly good idea of what to do, but I don't want to risk losing data, so I want to check and see what the best way to do this would be. Here's what I was thinking: along with the new drive, I bought an external enclosure. So, I was going to put the new disk in there, connect it to the computer with the original disk, and copy a clone of the internal disk to it. I was thinking of using Disk Utility or Carbon Copy Cloner to do this (although I have never done that, so I'd appreciate it if you could walk me through making a bootable clone with either one). Then, once I essentially have two disks which are clones, I'll swap out the old disk for the new one (I know how to do the physical installation). Any help would be appreciated! Thanks.
