Installed a new WD 250 HD last year and planning on doing a clean install of XP in the next few weeks. I have a question on HD partitioning. I have done a number of clean installs over the years with no problems. I normally delete the existing partition (C) and create a new one to install XP on. I want to create an additional partition to install my Flight Simulator programs on but not quite sure on how to do this. I have had a few lockups while running Fltsim on my C/ drive so that's why I would like to have the programs on another partition leaving XP OS and my programs on the C drive. Right now I have 188gb of free space and would like to allot 20gb for the Simulator programs. Will my XP reinstall CD let me do this or do I have to use a 3rd party software ? Just looking for a little advice since I have never done this before. Thanks.
