If you can see the drive icon on your desktop that is "seeing it in the Finder." If you double click the drive icon on your desktop does it open up a window showing the contents?
It must not be the same thing, because I can see the icon for the drive, double click on it, and use it, but it doesn't shoe in a finder window.
Like having a pic on the desktop and being able to click on it and opening it in Photoshop, but not being able to to " file" "Open" and locate that same image through a finder window and don't see it. Very weird...
