My iPhone 3GS used to sync without difficulty to iTunes 9 running on XP
I have recently updated to iTunes 10.0.1.22 on the PC and to 4.1 (8B117) on the Iphone 3GS
When I try to sync the iPhone backs up successfully but I get numerous ?error -50? when it tries to sync music. The song tracks themselves are not damaged in the iTunes library, they play via iTunes normally. Additionally, and alarmingly, repeated attempts to sync have wiped out most of the tunes on the iPhone, which have reduced from the 6207 there originally to 127.
I have two Ipod 5th generation and they get the same error and have started to lose songs, though not so many as I have stopped trying to sync
I have reinstalled iTunes clicking on the repair option ( i.e. I have not completely uninstalled iTunes) and it has made no difference, I have also bought and run a registry cleaner called Perfect Optimiser as it was recommended on some forum as a solution, and that has not improved matters.
I have also tried a different sync lead on a different USB port without success
I suspect the problem lies with iTunes and the PC rather than with the iPhones/iPod.
Can anybody tell me how to solve this ?
