last night I tried using my external seagate goflex hard disk(1 TB).My hard disk shows signs of powering on but does not get detected in both my disk manager as well as in my devices and printers menu in control panel.I had previously used my hard ware 1 day before and it worked flawlessly.I have filled the harddisk to the brim and full of personal files(all my childhood photos ).I appreciate any way to get the files or at least a part of it.
