I am about ready to resize my partitions on my desktop. My D drive is only 10 GB with the rest C drive. D drive is about full and I want to double its size. My hard drive is 250 GB. I was thinking of having the remainder as 70 gb C drive and the rest as the final drive. That would give me like 20 GB D drive, 70 GB C drive and whatever is left in the final drive. Right now C drive shows 162 GB free of 222 GB. My main concern is just making D drive larger. What programs are the easiest and most effective (screw up proof)? My OS is Vista Home Premium and I have noticed that many of the free partition manager programs are not yet Vista compatible.
