Rating : - Western Digital My Passport Essential 160 GB USB 2
I could not figure out how to get this device to work. It kept freezing up with partial page views visible. When the device was frozen, my computer ran very slow. I left it running over night and in the morning it was still frozen. I also had difficulty getting the device to stop. The "Safely Remove Hardware" icon also seemed to be frozen. Very frustrating.
