Tried just about everything but I still can't seem to get my external hard drive to show up in my disk management or computer. It say it's installed and ready to use but I don't see it.. only in the device manager and in devices and printers I can see it.. but nowhere else.. I'm working with windows 7 upgraded from windows xp but has be downgraded which was originally windows vista I think.. A friend gave me a computer and I had it upgraded.. can any one help me get my computer and external hard drive straight. Thanks.
