Ok so I'm new to this forum, so any help is appreciated. I wanted to change the icon for my HD on the desktop but when I did the get info for the image i wanted to use it wouldnt work. The upper left corner simply shows a jpeg logo image on all my photos! so it wont let me change the icon. I don't know why they are missing. I got a new hard drive 2 days ago from the Apple store because they told me it was faulty. Please help, thanks.
