The MyBook drive is connected via a 4-way USB hub to my Win7 laptop. The Smartware icon is on my taskbar. Randomly the Smartware window pops up full screen. I wonder if this is most likely due to a USB connection break, a power supply (to the WD) break, or some updating the software is trying to do?
Also sometimes when I start up I get a message that the Ext drive needs to be formatted before it can be used. But it shows up normally in windows explorer and seems to be fine.
