Just a note or everyone who is eager and tried this before oz_paulb's last post:
I have a 160gb and chose option to have partition 6 take rest of drive just to see what happened. The good news is that sure enough, I got and extra 20 or so GB!! But all my games, etc that were on partition f: were gone!!
Or were they?
If this happens...DON"T WORRY!! Just reflash your bios with option to use >137gb on partition 7 and all your items will reappear.
I'll have a clean 200gb to try tomorrow, and I'll post results then.
Thanks so much oz_paulb!
