I've had Seagate 2TB External Hard drive since around 2009/2010. ( http://www.newegg.com/Product/Product.aspx?Item=N82E16822148503
) I've played games off it, used it for extra storage and all. A year or so ago, it started clicking so I started using it less and transferred games off it. Today, however, the USB cord jiggled and came loose, leaving the hard drive hanging (even though nothing was running off it?)
kept saying something was running when I'd go to eject it, but nothing was being ran from the HD. Finally I just unplugged it, because I couldn't access it or interact with it through the UI in any way. Unfortunately, Windows 7 no longer will show it under "Computer". The Device manager shows a USB Mass Storage Device, but a yellow warning symbol, with no additional information I can seem to pull up. The driver is up to date (that I know of). No longer within Disk Management as well, but the grreen light on the external is steady on.
