Hard drive icon appears twice
The hard drive icon and MyBook for Mac icon appear on my desktop and in Finder. Neither set has the alias icon. Help!

Do these drives have names?
MyBook for Mac would likely be the external backup drive that you have connected. The other drive is probably you Mac's internal startup drive and would normally be named "Macintosh HD".
Appearing on the desktop or in the Finder sidebar is not a problem. It's a matter of choice. If you prefer not to see them you can change it.
Click Finder > Preferences... and select the General tab. There you can mark whether these drives appear on your desktop.
If you select the Sidebar tab, you can mark whether these drives appear in the Finder window sidebar.
