Upgraded to Lion and iTunes 10.4 and am now receiving a -50 error trying to sync my iOS devices? Anyone else? All of the support documents are for older versions of iTunes, so not sure they apply.

    I am having the unable to sync due to "unknown erorr (-50)" with iTunes 10.4 (80) on Snow Leopard when it comes to syncing photos (from Aperture 3).

     

    It occurs when it goes from "Analyzing photos" to "Optimizing photos" in iTunes.

     

    I have done the following in hopes of resolving the error:

     

    • Repaired my Aperture 3 library database
    • Deleted the "iPod Photo Cache" in the Aperture 3 library
    • Updated my iOS to the latest version
    • Repaired permissions on my Mac
    • Changed USB cables and ports
    • Restarted Mac and synced with only iTunes running

     

    None of the above worked... I am still getting this unknown error (-50) when it tries to sync my photos.

    I had the same issue.  I found an old thread that fixed it.  You have to delete the photo cache.  I just fixed mine right now.  All is well!

    Good Luck!

    Thanks. Though I already tried deleting the "iPod Photo Cache" folder. While it did re-sync all my photos again without the error, the very next sync, the same error popped up. So I still can't sync new photos.

    Yes it is happening to me too now.  So it works for maybe one or two syncs & then we are back with the same issue.  So it definitely has something to do with iTunes 10.4.

     

    Edit:  I was syncing some 2446 photos.  I deleted some albums & now I am syncing 2364 photos.  It appears I no longer bomb out.  So I must have a few corrupt files.  Or it is just something with iTunes 10.4.
