Hi,
Open start and search for cmd and right click and run it as administrator and then type the following commands:
sfc /scannow
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
Try disconnect all devices from your PC and restart your PC and try connect the hard disk and see if it works?
