Does anybody know what a sync error -39 is and how to fix it? I have iTunes 7.4.2 on my MacBook Pro. This error started popping up about a week ago. All my music, movies, podcasts, contacts, and calendars sync, but this error appears when I try to sync photos: The iPod "..." cannot be synced. An unknown error occurred (-39). This appears for both my 4th gen 20 GB iPod and my 2nd gen 8 GB nano. Although this error message does not appear for my Apple TV, the Apple TV entry has a warning icon to the right where the eject button would be for the iPods. I have tried rebuilding my iPhoto '08 library - didn't work. I tried Disk Utility on my hard drive - it verified the disk properly and permissions are fine. Any ideas?
