Okay my business build is complete. Everything is running fine. My intent was to install a second hd. The computer recognizes it however I don't know how to usr it as a backup if my C drive with the operating on it with my files does not see it . Iwas hoping to be able to drag and drop everything from my C drive to it. What do I need ti do to be able to use it as a backup drive. Does it make any sense to install a OS on it?
