I posted this with no results in another w7 forum. Perhaps I'll have better luck here. I have a small C: drive with too much stuff on it, and a new 250GB i: drive that is nearly empty. How can i interchange these two drives so the big one is c: and the little one is i:? I will rebuild w7 rc and the other stuff on the new c:, and move the data (already on the old i to a new partition on the new c:. Any help appreciated.
