My External Hard Disk is not resonping

Please I am Mr. Samuel Chukwuemeka. My WD External Hard Disk is not responding. It show white light when connected to the Laptop via it’s USB cable. May I know why it is not responding and how can I retrieve my documents from the Hard Disk. Thanks

emeka_samuel,

What external disk drive is the one affected? When did it start to happen? Does it work on different computer systems? Have you tried changing the USB cable?
