so, I have tried what the people who have posted the suggestions to deselect all of my music and when I click "sync", it still brings up the error. what can I do now?
for my iphone, the fix was definitely clearing out the **voice messages** that were _0 seconds_ long. after i deleted those voice messaged from the phone, my phone sync'd immediately without any further problems.
Hi There, i used to see this error every day on my computer, and i did all the things that this post says, and nothing, sometimes it syncronises it, sometimes not. deselecting: music, voice memos, adding folders, lists, etc. Everything worked for one or two syncs, but then usually, the error came back.
One day, i changed the hard drive of my computer (windows 7 based) and reinstalled de whole thing, and i realized one thing, before installing everything, i sync the ipod and it went perfectly, i did it like 5 times and went brilliant!, the again i continued to install all my stuff. After i've installed all i needed, i try to sync again, and to my surprise the flippin 13109, came back, and i go back on the instalations, and realized that installing bittornado, a P2P program to download torrents was the problem, next thing to do, uninstall the program, and since that day (like seven months ago) the ipod syncs without problems, works perfectly, records voice memos, sync apps, etc.
I think, because this programs makes chganges on the windows firewall, this changes affects directly on the ipod software, and it could be like a trojan, inserted there to prevent you do some use on this programs, and download free music from intenet.
That Worked for me
Ipod Touch 64 gb third generation.
windows 7 based.

so I think I know why I am getting this error. I have iTunes on both my laptop AND my desktop. It seems that, even though I am not syncing with my desktop computer, itunes on my desktop messes something up when I connect the ipod to charge. I restored my ipod and synced and everything works fine.. have tried syncing multiple times, but the first time I connect my iPod to another computer, I get this error.
So.. to NOT get this error, don't connect your iPod to any other computer than the computer you connected it to. Don't even try to charge your iPod on another computer.
The only way i could get rid of this error was to restore my itouch. I thought i would loose all of my music too but thankfully it doesn't delete it from your library.
So my advice is to restore, i tried everything esle and it didn't work. I REALLY hope this helps.
Count me in as a "delete all your voice memos to fix" vote. Unfortunately, I didn't read about the possibility of the zero-second memo as the culprit, or I would have only deleted those first.
This seems to be a pretty long running problem for Apple to either (a)not have fixed it or (b) manged to teach their programmers how to identify
where a syn failed. Guess that's form over function.
Just unselect "Automatically fill free space with songs" and it gets rid of the problem. I guess iTunes just gets confused sometimes and tries to put on songs that can't fit which creates an "unknown error"
So after about a week of syncing without an error, I finally received it again. Only thing i did differently this time was stop the sync halfway through syncing by sliding the button over to manually stop the iPod from syncing.
I will also deselect the "automatically fill free space with songs" feature to see if that affects anything.
I have had the same UNKNOWN ERROR come up since the most recent iTunes update. Only thing i could come up with is a mp3 issue. I had 1000's of songs i just updated with one play list 75 songs. Adding songs back as i go along. Synchs fine now. Hope this helps someone. I was frustrated too.
update: went a few days without a syncing problem, but then i got the error again last night. Unchecked that "automatically fill free space with music" and it I was able to sync. After syncing, I checked the box again, and itunes filled my ipod back up with music. Seems like un-checking this option is a fix for this issue.
I am having the same problem. I tried calling the support line but they want to charge you $30 just to give you advice over the phone, advice which may not even work. Seems like this is a fairly prevalent problem for Apple devices and you would think that after spending anywhere from $200-$600 on a product they would be able to offer more help on how to fix it. I tried unchecking the music during sync and then re-checking it but had no luck. I am restoring my Ipod right now so we'll see if that works but if I am going to have to do this everytime I want to update my music I'm chucking my Ipod and getting a Zune...
Nothing is working! ive unchecked the voice memos. ive deleted my voice memos and i still get the error. ive even unchecked my music and synced and checked it and synced and nothing seems to work PLEASE HELP
