I upgraded the internal hard drive in my MacBook Pro and cloned it from my old one via SuperDuper! after a Time Machine restore failed to boot. However, now the new hard drive's icon no longer sits in the top right corner of the desktop, despite it being selected as the startup disk. Instead there's just a huge gaping hole. If I move it there and then "clean up" the selection it shoots off down the other end of the desktop. How can I permanently have the HD icon back where it used to be? I've tried repairing permissions and deselecting and reselecting the display of HDs in the finder prefs but neither worked.
