Currently i have a single HD partitioned into 2 (c: & d i want to format the c: (which has the OS on it) but dont know if that would also rid me of my d: partition i also heard that you can use your xp disk to perform a new/fresh install of xp (repair?) w/o loosing any data that would involve renaming the prog file and that the new install rids the old xp install w/ a new one? Im not completely computer illiterate, so any suggestions would be helpfull. cliffnotes: Basically trying to keep my d: from being deleted. Im not sure if both or only the c: will be gone forever, thx in advanced.
