For my purpose, and I think most anyone in my situation, this is a key |
| 9 |
issue. I built this AMD64 machine 2-3 years ago. Any drive I put in |
| 10 |
today is going to have completely different drive geometries. |

I am buying a drive today and will hopefully get started on this |
| 13 |
project this evening to tomorrow. I'm leaning the gparted-clonezilla |
| 14 |
direction but not overly confident at this point. Still have much to |
| 15 |
learn. |
