I have a WD Book Essentials 2Tb USB 3.0 and I can’t get it to work all of the time, been an issues since I got a new computer with Win 7. Sometimes it shows up as a drive and is accessible and sometimes it’s not there at all. Sometimes it’s there, has folders, but no files in the folders, the drive always spins up, the light is always on. Most of the time Win 7 doesn’t recognize the drive, it’s there but software is bad. I have updated the firmware, installed WD smart wave software, WD drivers and it’s the most temperamental drive I have ever owned. If I unplug it from wall and USB and plug back in it sometimes is recognized and sometimes not, I need help.
