I saw a youtube video explanation about very easy way to assign letters from the mgtm. part of control panel for your drives. But I am unsure if that works same way with DVD drives. I have SDD (c) drive and a virtual Drive (e) and two DVD drives, (d)&(f). I am getting ready to set up my hard drive for first time and would rather not set it up as g but rather as d. Would that be a problem? Should I reassign my DVD first, then be able to choose D for new hard drive?
