I have a WD My Book Essential with product number WDBACW0010HBK-00 and serial number WCAV5P296696 and a Windows 7 PC. Sometimes it disconnects, and it’s not because of the cord, the power, better performance, or selective suspend. I was why this is happening, and how I can stop it. Also, how can I figure out what is causing this?
