Hi, Basically I would like to swap my current 120GB HDD with a 320GB model. The only thing is when I read about what to do online, it seems the procedure is as follows: 1. Create a back up using SuperDuper or TM. 2. Boot from this back up. 3. Use Disk Utility to format your new drive to GUID and then Restore. However what I would like to do is as follows: 1. Buy a 320GB 2.5" HDD and enclosure. Install the 320GB in the enclosure. 2. Format it as GUID and use either SuperDuper or Carboncopy (preferable, as it's free) to create a copy of my MacBook HDD. 3. Remove the 320GB from the enclosure and swap it with my current MacBook HDD. 4. Switch it on and be up and running as normal, except with an extra 200GB. This seems far simpler, and as I don't currently have an external HDD, but I haven't seen this method anywhere on the internet and therefore I'm slightly doubtful as to whether it will work. Any help in this matter would be much appreciated. -Harry.
