if you need to reformat, you can save anything you dont want to lose on the x side of your partition.
if you use windows xp, you will be asked what part of partition you would like to format, if you choose the c partition you will clean all from it including your oppeating system. you would then have to reinstall it with your windows disk. you could then move your saved files back from partition x.
i am not an expert, but i think it works something like that.
