I intend to use the Win 7 East File Transfer when I upgrade from Vista Ultimate to Win 7 pro. I intend to use the clean install method. If I add a second physical internal hard drive, can I use that instead of a physical external drive? All documentation always refer to an external drive. I am aware that I must do it in two passes - first export and then after the apps are re-installed, import my settings etc. Hence has anyone ever used a second internal drive with EFT?
