My Book Essential USB 3.0 suddenly doesnt show on my Windows 7 laptop. I plugged it into my Windows XP system and it works fine! 

On Windows 7 laptop I get the following error, in additon to device unrecognizable:

Any suggestions? Please help!


You might be experiencing two issues.

Make sure that the drivers of the unit are being properly installed by the computer.

Also, make sure that the drive is being connected to the wall outlet power source to confirm that the unit is getting enough power.

Regarding the drivers of the unit, you can download that from the WD Support site on the following link.
