I have a dektop computer and my father has a desktop computer. We want to switch computers but we want to keep our hard drives. When we trade computers, is it just simply taking my hard drive out and putting it in his and vice versa? My computer is running WinXP Home, on a Compaq Presario with 600 MHz, 512 MB RAM. His is a custom built computer running Win98 with 1600 MHz, 1 GB RAM (see why I want to change?) and my hard drive is 60 GB and his is 30 GB. Can the hard drives just be switched? Or is there other stuff I have to do? Will they have to be reformatted? Are my questions confusing?
