I'm running XP Pro (including SP 3) on a 62GB partition of a 250GB drive and would like to clean-install XP Pro on the second partition of 170GB. My goal is to retain everything now running on the smaller partition, gradually reinstall desired programs on the second partition, and selectively copy data files to an external drive, then move them to the second partition. Getting that second copy of XP set up on the second partition is the first step, so I would like to hear from anybody who thinks this is not feasible, as well as from anybody who has done this and can point to a very specific step-by-step procedure. Many thanks.
