I just made myself an external hard drive using http://www.amazon.com/MSI-Enclosure-SuperSpeed-Connection-HD-250TN-U3/dp/B004L9JZ9S and http://www.amazon.com/Western-Digital-Scorpio-Internal-2-5-Inch/dp/B004I9J5OG . It works fine, but when it comes time to unplug it, I get an error using Safely Remove Hardware, that the device is still in use by one or more programs, even when I close all my open programs. Any solution?
