well i guess ur right about that, xp can be very confusing with many hdds and partitions. raid 0 and a backip drive is an excellent idea. but you are going to have to find a way to move your current data. that means either buying a new hdd if u have the money and want more space. or you could transer all of your data to another computer if that a possiblity, you can do this over a home network. or if there isnt too much data, burn them all to dvds.
