I have tried to run western digital data lifeguard but it also gets hang when a hard disk is connected.I have tried to connect disk management service but when a hard disk is connected,it is not getting connected to disk management. I have tried device manager . It shows WD device and there is no yellow or any triangle. Everything else works fine after removing a hard disk. Help me. Thank you.
