I have a copy of all my photos on an iPad1, transferred via iTunes, roughly 7000 of them. Today I tried to sync roughly 200 new ones, including 1 video, but only got 7 transferred and an error message saying that some MOV files could not be transferred and nor could some JPEGs. Most of the files had not given rise to an error before. Any ideas why only some of the recent additions might not be being transferred. The pictures were taken with a Canon 550 in RAW mode, but so have many of the ones already on the iPad. I am thoroughly confused. There is no problem with space on the iPad according to the gauge in iTunes !
