Even if it does clone the ~150 GB partition, it's really easy to resize it later on, from within Windows.Also - My current HDD is 160gb and the partition is like.. 150gb or something. My blank HDD is 320GB and I don't want it to just make a 150GB partition on the blank one, I want it to make the max size it can but still have all the stuff on it.

Looking at the manual there, it looks like it should work just fine (and automatically enlarge the partition as you wanted above) - their steps are under Chapter 13. It might be worth trying to do as you said: format the disk and see if it shows up, although the guide does say it checks if it's empty vs. has stuff on it, and prompts you about losing the old data...:freak:
