I have a 5G 80Gb iPod which up until last week has been working fine. Now I get a sync error -50. I have restored the iPod and the first sync was fine, but since then cannot sync and get the same unknown error (-50).
Anyone know what -50 means?
I have iTunes 7.3.2 (6)

Powerbook G4 1Ghz Superdrive, Mac OS X (10.4.10)

    I have found an answer in the iphoto forum. I had a / mark in the titles of one of my albums. Changing this has resolved the problem

    I found that this error can also occur if you have "problem" characters (like slash '/', single-quote ''', or double-quote '"') in both iTunes song/album titles or iPhoto photo/roll/event titles!

    For me, removing these characters from my iPhoto photo/roll/event titles as allowed me to sync my photos to my iPhone (which wasn't working before this fix) and to sync my iPod without having to reset it EVERY time (even though I wasn't syncing photos to the iPod at all).

    I hope Apple fixes this bug, which is still present in the last iPod/iPhone software (and iLife '06 and iLife '08) as of today (2007-09-02).

    It isn't a bug, these are illegal characters in file names for the operating system (the same applies to some characters in Windows).

    Nope, these are perfectly legal characters for filenames in Mac OS X. I use them all the time with no problems until this one. They can even be used via OS X's UN*X command line if properly quoted.

    Sorry, should have said for iTunes instead of operating system...remember iTunes is also used in Windows, where these are illegal characters. And iPods now come formatted as FAT32, where again they would not be legal characters.

    I'm getting the same problem. I used your suggestion and it worked a first. Maybe there's some characters I can't see. Could it be anything else? Where do you go for service on these devices. Any suggestions? Not sure where your located but I'm in Florida in case you now some place nearby. Thanks.

    I had the same problem: iPhoto albums did not show up in iTunes and syncing to my iPhone worked for all but the photos. Error (-50).

    What worked for me worked was what others have said here, bad characters in the comments of my photos. A very easy way to find them was to look for the offending comments in the AlbumData.xml file (Pictures>iPhoto Library>AlbumData.xml). I did this by right-clicking (control-click) and selecting "Open with..." and choosing Safari (v3). This opened up the AlbumData.xml file, but as it was opening the long XML file, it stopped with an error on line blah blah.

    All I did was to scroll down to the bottom of the page in Safari, and look for the last photo at the very bottom, then went to this photo in iPhoto. I deleted the comments.

    I had to repeat the process 3 or 4 times, but got all the "bad" comments out and that worked!!

    Finally. Easily. Ahhhhhh!!
