....the system detects that the expander is there and then asks if you want to format it. When you select "Yes" it tells you that it could take up to 30 minutes and to not disconnect it until its done. The only option in the menu on the right side is "Close". There is no progress indicator to tell you how the formatting is going - how do you know when its done? Does it just finish running in the background if you hit "Close"? Is it OK to watch TV while its formatting? There needs to be some additional information provided.
