I keep getting a message when I sync my ipod touch saying "Itunes could not copy "name of the song" to the ipod "name of ipod" because an unknown error occurred (-50)" Plus not all my songs are syncing only partially. I have tried alot of things and read discussions relating to this issue and I'm becoming very fustrated with situation. Thank you!

iPod touch, iOS 5.1.1

    Error 13, 14, 35 and 50 (or -50)

    These errors are typically resolved by performing one or more of the steps listed below:

    1. Perform USB isolation troubleshooting, including trying a different USB port directly on the computer. See the advanced steps below for USB troubleshooting.
    2. Put a USB 2.0 hub between the device and the computer.
    3. Try a different USB 30-pin dock-connector cable.
    4. Eliminate third-party security software conflicts.
    5. There may be third-party software installed that modifies your default packet size in Windows by inserting one or more TcpWindowSize entries into your registry. Your default packet size being set incorrectly can cause this error. Contact the manufacturer of the software that installed the packet-size modification for assistance. Or, follow this article by Microsoft: How to reset Internet Protocol (TCP/IP) to reset the packet size back to the default for Windows.
    6. Connect your computer directly to your Internet source, bypassing any routers, hubs, or switches. You may need to restart your computer and modem to get online.
    7. Try to restore from another known-good computer and network.





    "Error -50," "-5000," "8003," "8008," or "-42023"

    These alerts occur due to timeouts or conflicts trying to write a file during download.

    If you encounter this issue while accessing iTunes Store:

    See iTunes 9: "One Moment Please" or "Error (-50)" message when accessing iTunes Store

    If you encounter this issue while while downloading something from the iTunes Store:

    Delete your iTunes Downloads folder, located in:

    Mac OS X:
  ~/Music/iTunes/iTunes Media/Downloads   Note: "iTunes Media" may appear as "iTunes Music. Also, the tilde (~) refers to your Home directory.

    Windows Vista:
  \Users\username\Music\iTunes\iTunes Media\Downloads\

    Windows 7:
  \Users\username\My Music\iTunes\iTunes Media\Downloads\

    Windows XP:
  \Documents and Settings\username\My Documents\My Music\iTunes\iTunes Media\Downloads\

    After locating your iTunes Downloads folder:

    1. Quit iTunes.
    2. Delete the Downloads folder on your computer.
    3. Open iTunes.
    4. Choose Store > Check for Available Downloads.
    5. Enter your account name and password.

    If you encounter this issue while while downloading Digital Copies using Windows:

    Use MSCONFIG (directions for Windows XP and Windows Vista/Windows 7) to disable conflicting software.

    If using MSCONFIG steps resolves the issue, you may want to use the System Configuration Utility to turn on the third-party System Services and Startup Items one at a time (restarting your computer after turning on the item or items) to identify which System Service or Startup Item is causing the conflict.

    You can turn all of them back on by selecting the Normal Startup option under the General tab of the System Configuration Utility window, but please note that this may cause the issue to reoccur.

    If you are able to isolate the issue to a particular third-party software, you may wish to contact them to let them know of the conflict.

    Hi Jessica,


    Did you find a solution to this problem?  I'm having the same issue.  It's not related to any of the help items.  I can copy some files from the same CD I ripped using Applie iTunes on this same computer.  Some of the files give error 50 some don't.  It's very strange.  Then I see even stranger behavior when I try copying songs individually.  Different songs get copied - then it will eventually hit a song with error 50 and stop.  This is really annoying.  I would like to use my ipod again. Especially after the software upgrade.  Seems like this version is worse than the previous version:(

    The same problem here.

    I can not sync the iPod... First it starts well and it is fast then it gets slower and I get the -50 error.

    Then the iPod can not even be ejected!

    The treobleshooting USB-related did not help.

    I will try the other things one by one.

    Hopefully we'll get somewhere...

    I was having this same problem in OS X with my very-old iPod Photo, and switching cables seemed to fix it. Thank you, lllaass

    Thank you. Your Mac OS X suggestion worked.
