I have an 80GB Hitachi SATA HDD that I'm replacing with a Seagate 500GB SATA. I have initialized the new drive, but I can't figure out how to assign a drive letter to the new drive until after I partition it. I don't want to lose 420GB of space so what can I do? need help fast because I need to have this done this weekend! I am Ghosting with Norton Ghost 14.0. Please HELP!!!
