iPod cannot be synced. Required file not found?

OK, everybody and their aunts are having this problem. Seems to happen on both Apple and PC platforms but more on PCs than on Apples. I feel that the primary culprit is the auto-synching that causes this error. I found that disabling the auto-synching solved the problem of this error box. As long as the error box doesn't show up, you will be able to do whatever with your iPod since it will show up on the iTunes software. Right? OK. So try this guys. From iTunes... EDIT, PREFERENCE, DEVICES, check PREVENT IPOD/IPHONE AUTO-SYNCH option, then RESET SYNCH HISTORY. Then OK. Now see if you see your iPod in iTunes. Try reconnecting your iPod. This disabling of auto-synching and reseting sync history solved the problem for everyone experiencing this annoying error box. That error box prevents your iPod from showing up in iTunes making you unable to do a darn thing right? So, give this a try.

Ok, I hope somebody finds outs something. I get the same error message. I just bought a new 16g nano and it synched all the music just fine but gave me the error message when trying to synch the photos. Now on the ipod when on the photos menu I get a scrolling marquis at the bottom showing my pics but when I select that menu I get blank screen but for the words at the bottom "No Photos. You can synch photos from iTunes." No I can't!

I did as you said and it seemed to be worknig at first...I saw the files begin to transfer and was like "YES victory at last!" But then part of the way through, it just stopped and I got the same error message again =/

Hi all,
Had a similar issue, but it may not be the same one, as it seems to be occurring on windows aswell.
Nevertheless this blog helped me fix it in an apparently legitimate way for those with a mac. Perhaps those windows people out there can use this to help with their problem.
Hope it helps.

i had this problem with my third generation 4G nano. through itunes i just restored it/updated the software and it was able to sync after that. not sure if people have tried that yet or if it will work for everyone, but its worth a shot.

Aloha All:

I talked to Apple about this problem.

They offered several reasons for this message:

1 - One of the music files cannot be found by iTunes. This is denoted by an exclamation point ⚠ in front of the song title
2 - One of the music files has a zero length
3 - One of the music files is corrupted.

They suggested I step through my playlist song by song (no easy task for a 1500+ song list) to find the zero length or corrupted file. Since I had just added some music to the playlist, it was easy for me to isoloate. (I didn't have files that couldn't be found by iTunes.

Good Luck
