WD1600 Continuous Read Cycling on power on

I have a WD1600B008-RNN external USB drive that was working satisfactorily.  I had to relocate systems and upon restart the drive just spins and stops spins and stops.  This does not cease with time.  Is there a way to resolve this? 

Thanks for any input.  I have a lot of back up data on this drive

I recommend that you try some basic troubleshooting.


1- Disconnect the drive from the computer and restart the computer.


2- Please try connecting the drive to the back USB port of a desktop PC and use another USB cable if possible(directly to the PC, not through a USB hub).

3- Make sure you hear the connection sound windows makes when recognizes a USB device.


4- Go to "Disk Management” to verify if the drive shows up there.
