I am wanting to use 2 usb drives for backup. i am using one drive at a time and when one backs up i swap it with another so that i can take one offsite. does anyone know how to assign 2 drives with the same drive letter. I wouldnt be plugging them in at the same time. I want it this way so that i wont have to change the drive letter every time. Is there any drive management software out there that will do this? Please help me!!!
