I have only 1 HD in my system (80gb) which i want to replace with a new larger drive. i plan to keep the 80gb but i want to set the new larger drive as the one with the vista install on it along with all my programs. whats the easiest way to do this. i don't really want to have to install all my programs and anti-virus again. can i just leave the 80gb as the C: drive and install all my larger programs/games to the new larger drive as secondary? would doing this slow down response time to the games at all? Or is there a way to move everything over to the new larger drive without reinstalling anything?
