Same problem with my new iPad 3 64 GB 4G.
- Synching of large quantities of movies, data files etc via PC is going on w/o any problems.
- Synching photos is a mess. iTunes shows that f i 2000 photos were synched, iPad gets maybe 100-200.
I tried all tricks I know (including rebooting the computers, using different cables, different USB 3 and 2 slots, reinstalling iPad). I use a fast PC (w GA-/68XP-UD4 motherboard, SSD, 16 GB RAM) and a medium notebook Toshiba Satellite.
Solution to that mess (at least for the moment):
- synching photos via notebook; takes really quite a while but works perfectly well
- synching everything else via PC
It reminds me of my beginning with Windows. One had to find solutions for problems one never had before and MS didn't care of. It seems Apple is adapting basic management from Microsoft...
Maybe this synching problem it is a matter of speed either in iTunes or iPad. The PhotoCash of iTunes shows less pics than the information says. Synching loads of pics with iPhone 4S works fine via PC.
I hope that Apple is finding soon a solution for that problem. It is nasty to have to use TWO computers for synching ONE iPad.
