For my purpose, and I think most anyone in my situation, this is a key issue. I built this AMD64 machine 2-3 years ago. Any drive I put in today is going to have completely different drive geometries. I am buying a drive today and will hopefully get started on this project this evening to tomorrow. I'm leaning the gparted-clonezilla direction but not overly confident at this point. Still have much to learn.
