Here’s how to try it: From the Finder, pull down the Finder menu and select Preferences — or just press Command-comma [⌘ ,] from within the Finder. Click the General tab and uncheck Hard disks; CDs, DVDs, and iPods; and Connected servers.
Next, click the Sidebar tab and check the boxes next to all the items you unchecked under the General tab.
When you want to access a drive, disk, or server, just open a Finder window by pressing Command-n [⌘ n] from within the Finder. And when you close the Finder windows, your desktop will be spotless. (Remember, Command-w [⌘ w] closes a Finder window, and Command-Option-w [⌘ ⌥ w] closes all Finder windows at once.
