WD My Passport 500gb portable

Installed a new WD My Passport Ultra 500gb portable drive last night on my laptop (Windows 7).  Seemed to be fine.  This morning it is not recognized.  Re-installed driver from WD website and it still is not recognized.  Working fine on my desktop (Windows 7).


If it is working on your desktop and not on a  laptop it is possible the laptop is not providing enough power to make the drive spin properly. I recommend that you contact WD support directly to verify if they can send you a power booster cable (Y cable)
