I have vista ultimate, i have 2 partitions, 1 for the vista installation & 1 for my data files. Their on 1 500GB hard drive, C:172GB & D:292GB. I just need to make D: go up to 380GB & take C: down to 90GB without losing the data on D:. Also don't say just buy another hard drive because i don't want another one at the moment but i need more space, i'm just trying to work with what i've got. Thanks
