My 160GB classic recently stopped displaying any of my photos synced with it. Scrolling to the "photos" menu on the iPod reveals 5,600+ black boxes, but no thumbnails or photos ever show up. When I select one of the boxes (which I assume to be thumbnails), I can hear my iPods hard drive whirring and clicking. Please oh please tell me that there is a preferences or plist file that needs to be changed/deleted to fix this and that it's not a hard drive issue.
