I attempted to add some music to my jailbroken iPod Touch 2G, from a large iTunes music library recently, only to get: 'The iPod "Aussie Guy" cannot be synced. An unknown error occured (-54).' Now, I could probably add music using gtkpod under linux, but iTunes, for all its problems, is very convenient sometimes. How do I resolve this error and have my iPod talking nicely with iTunes again? Thanks, -A.
