My external hard drive stopped working today, it was working fine until around 4pm when I unplugged it and restarted my PC to uninstall a program, when the pc came back on, the HDD would not be recognised by my PC. The port is fine because I tested it out with my usb 3.0 mouse and that worked fine, and the HDD worked on my other PC when I tested it, so I want to know why it doesn't work now...
