When I try to remove my external HD by using Saftly Remove Hardware, I get the warning pop-up "Problem Ejecting USB Mass Storage Device". In the box it reads "the device generic volume cannot be stopped right now. Try stopping the device later". Everything is closed and over an hour has gone by. Everytime I try to eject it I get the warning. I hate to just turn it off without properly ejeting the HD. It's a Western Digital My Book external HD. Any help would be appretiated.
