So my iPad sync problem was not caused by a corrupt photo cache. I finally dumped USAToday for iPad and not synching is quick and painless. I will miss their crossword puzzle and day in pictures.
I was having problems synching my iPad. I kept getting errors and had to reset the iPad to get it to work.
I restored and waited 2 hours to find out it failed. Well, not entirely. It would quit when it go to the photos.
I went to google and found similar issues from way back. The suggestion was to delete the iPad photo cache. I did and it sync’d without error.
