I have 120GB iPod bought December 2008. I've never had any issue with it and everything was working fine. Then 2 days ago I tried to put some music on it, however an error popped up saying that certain song could not sync. I looked around the internet for a solution but to no avail. I then decided to restore the ipod to its factory settings in order to put my library back on the ipod. Of course it was annoying having to put all my music back on but I was willing to do it. However now I can't sync more than 700 songs. I've tried it few times and every time it stalls after 700 songs and says the songs can't sync to the ipod. Different errors keep popping up when it gets to 700 songs, sometimes -50,-53, -1330 etc..... Please, please someone help. Much appreciated
