ITunes syncing: unknown error (-50)

Whenever I plug in my iPod Shuffle to sync my music a pop up comes up saying 'iTunes could not copy {song name} to the iPod {iPod name} because an unknown error occured (-50).' It happened after it asked me something to do with iTunes Store purchases that were on my iPod but not on my PC? Thanks in advance

If it's any help I've found that it won't sync only a certain foreign album. If I untick it and have 'Sync only ticked songs' on then everything else syncs fine. Could it be something wrong with the files themselves
Aha. Could be the missing link here. Were these files imported to iTunes from an outside source or downloaded from the iTunes store?
If they are imported from outside of iTunes, try removing these tracks and re-ripping them if at all possible. What format are they in?

TS1425 5th Generation Nano iPod. The iPod syncs on iTunes when I connect it to my MAC, but when I try to add a song from iTunes to the iPod, I receive the message "Cannot be synced, unknown error occurred (1039)

5th generation iPod Nano - iPod syncs with my iTunes and I can see it in iTunes, but when I try to move a song from my iTunes to the iPod I get an error message "Cannot by synced, Unknown error occurred (1039). System works fine with my 4th generation iPod Nano. I'm afraid to "RESET" my iPod because I may not be able to restore my music and videos afterwards.

Hello Ventanilla 97,
I agree with planb77 with recreating your itunes library. That will fix your issue. If you would like more step by step info go here:

Can't sync nano since installing itunes 10 - "unknown error"

I haven't been able to sync any music to my 5th gen nano since updating to itunes 10 - it tells me something like "ipod cannot be synced - unknown error", or else just refuses to acknowledge the sync at all. The strange thing is, when I connect my ipod to itunes, the songs I've tried to sync appear in my ipod library under 'devices' (itunes seems to think they HAVE been synced), but when I check my ipod, they're definitely not there.
I've tried reinstalling itunes and reloading my library, but it's made no difference. My ipod software is up to date as well.
Any help would be great, as troubleshooting doesn't seem to cover this issue.

Okay it turns out that this is an error 13019, yet itunes support seems to think this error only occurs when syncing to an iphone or ipod touch, not a nano....! So it doesn't suggest any fixes for the nano.
And I tried an earlier version of itunes but the error still occurred, so I guess it has nothing to do with itunes 10 after all.
I've read about 'restoring' the ipod to get rid of this error, but will this delete all music on the ipod? I have music on there that I no longer have anywhere else so it would be a shame to have to lose it just because apple can't offer a better fix.

When i tried to sync my ipod it said "cannot sync. unknown error has occured(-39)

when i tried to sync my ipod it said "cannot sync. unknown error has occured(-39)" how do I fix it??

Are you syncing photos to the ipod? If so, the -39 in this context can sometimes indicate a damaged photo cache. Are you able to sync if you delete your existing photo cache? To find it, see the following document:

Keep getting message "ipad cannot be synced, unknown error (1150)...what does that mean?

Whenever I try to sync my iPad I keep getting message "iPad cannot be synced, unknown error" with code (1150). What does that mean?

This happened to me after I upgraded to iOS6.
Tried everything I could find in a common thread here on the site, but what finally worked was...well, the last thing I did before it allowed a sync, I guess I can't say for sure that this is the problem, but...somehow, in the sync settings for the iPad, the "Sync Only Checked Songs and Videos" box had become unchecked. Clearly, there isn't enough room on the iPad for everything on the laptop, so I think this may have been choking it.
Worked fine at that point.
And, for what it's worth, I looked at the Music tab for my iPad in iTunes, and THERE it said only to use selected artists and playlists, but on the main SUMMARY page, the box was unchecked.
Oh, and I updated all the apps on the iPad (73 updates??) before trying the sync, so that might be a factor too.
Good luck.

Cannot Sync Unknown Error -50

OK, here is the issue as concisely as I can put it. I have just updated my iPhone 4 to iOS 7.0.3 and updated iTunes to 11.1.2. Today I downloaded an app from a third party site (reputable) which then opened iTunes and clicked download. I then went to sync my iPhone only to discover I was logged into iTunes as, my Apple ID. Unfortunatly being an early user of iTunes my iTunes and App Store login ID is not my Apple ID. So I logged out of my Apple ID and logged back in using my usual login and password which is the same on my iPhone for iTunes and App Store. I then received a "this iPhone cannot be Synced Unknown Error -50" The app I downloaded appears in each login but the phone stops syncing when it reaches apps.
So should I delete the app from my purchases in my Apple ID login and try again? I have already removed it from my Mobile Apps folder.
And can I get rid of the Apple ID account in iTunes? I have checked purchases in this account and apart from the app I downloaded today ther's nothing in it.
Is there a way to merge the two accounts?
I'm confused.

How to fix "Sync encountered an error while syncing:Unknown error."

In mid July, after the firefox update, I had decided to close firefox like I usually do before I open the client for my MMORPG Aion, so I did. I end up not turning on firefox for a few days and when I did my bookmarks were gone as well as my toolbar bookmarks and my history. I start to wonder what happened and then I realised that there was a grey bar at the bottom of my browser stating, "Sync encountered an error while syncing: Unknown error. Sync will automatically retry this action.." I had no idea why this would happen as I never had this problem before so I look at the firefox support database but since I'm quite the greenhorn when it comes to programming there was only so much I could understand. I did try looking for corrupt or locked profiles but I saw none. Now as of today it's going on 2 months since the problem began and just today I recieved the firefox 32.0 update but still have this problem so I'm at my wits end and I not sure if I'll ever get it working again. Also my sync account is the one under the new system I had updated a few days before the problem began it also seems to be working on my other devices. Im lost without my bookmarks please help.

Sync encountered an error while syncing: Unknown error.

Bookmarks vanished on multiple computers.
Error message on all platforms: Sync encountered an error while syncing: Unknown error.
Android device seems unaffected. Attempts to re-sync good data from android device have no effect.
I filed a bug report but after over 15 days it was marked as a duplicate and rolled into another bug report.
The solutions there are way (WAY) beyond my technical level of expertise, and look to be for the unix OS.
Something about a corrupt root.
I've been very reluctant to clear my sync data, because the impression I get is that I'll lose all my bookmarks. The entire reason I started using Sync was to back them up!
Computer1: Win7 enterprise sp1, 64bit. Firefox 17.0.1
Computer2: Win7 enterprise sp1, 64bit. Firefox 17.0.1
Android device: Dell Streak7 Android 3.2 Firefox 17.0

If you've lost bookmarks then you should make a backup copy of the JSON backups in the bookmarkbackups folder.

Problems with bookmarks and history not working properly can be caused by a corrupted places.sqlite database file.
You can check for problems with the places.sqlite database file in the Firefox Profile Folder.

If your iTunes is up to date, remove the SC Info folder.

Itunes Purchasing Unknown error

When I get into the iTunes music store everything loads completely fine, all my searches, everything I click on, fine. However, whenever I click BUY SONG, try to purchase anything from the store, view my store account, or something else similar, I get unknown error (-9813). HELP PLEASE, I CANT BUY ANYTHING AND MY NETWORK CONNECTION IS FINE!!!

I'd suggest you ask this question in the iTunes forum rather than the GarageBand forum to get answers about, well, iTunes.
