I have a 60GB iPod w/photo capability and the newest software (1.2.1), iTunes (6.0.4), and iPhoto (5.0.4). Whenever I plug in my iPod recently it gives me an error message: "The iPod "iPod" cannot be updated. An unknown error occurred (-50)."
I have tried both USB ports. Didn't work.
I have reset the iPod. Didn't work.
I have restored the iPod. Didn't work. The iPod loaded my songs but the iPod would not load my photos from iPhoto (and, consequently, my Address Book contacts since they are done after photos). So it seems to be a problem with iTunes-iPhoto-iPod.
I have also on a suggestion used Disk Utility to partition my iPod. Didn't work.
Any suggestions? Anyone with a similar problem?
