I have a WD 500GB external hard drive that is not being recognized by my computer anymore. It just stopped working. When I plug the USB cable in, Windows recognizes that the device is there, and says that it has installed the approapriate software for the device and it is ready to use. However, the drive does not appear in My Computer. Also, I have right-clicked on my computer and then the Manage option, and under Disk Management, I do not see the drive. I have all of my sports games and music on the drive. I just need some help on how to solve this problem.
