I had to reconfigure some connections inside my box, and inadvertently switched the order of my SATA drives. In short, Windows loaded with my optical and 2nd HDD swapped, so it assigned them letters. All the icons that looked in D: switched to the "broken" icon. I've since switched drive letters and rebooted, multiple times.
Right clicking on the icon and selecting Properties displays the correct icon under the "Shortcut" menu. How can I get that icon to show on the desktop now?
