you had the right idea, plug both harddrives in and just copy the data over. BUT, if you the ENTIRE harddrive (Operating System, Account settings and so forth) to remain in place, you will need to use a program that will be able to transfer the data.
Although it IS old Norton Ghost would copy your entire harddrive to a new one. I'm not sure what any newer programs are called, since I simply install the Operating System onto the new harddrive, copy the files I want and continue.
