PLEASE HELP:cry:

You may try plugging the power adapter to a different outlet, directly to the wall.  If still not detected you may retry the firmware update.  If this is not possible you must contact WD for a replacement.

If you retry the firmware update make sure your Adobe Flash is up to date and that your AV is off. Make sure you follow all of the steps on power cycling.
