Question: An unknown error occurred (1156)

Since updating my iPad to iOS 6 and updating iPhoto to 9.4, I have been receiving the error The iPad <name of my iPad> cannot be synced. An unknown error occurred (1156).

  1. My photo's won't sync (turned off syncing for all photo's to see if that works but when on shows .98 gigs)
  2. My video's won't sync (status bar shows 13.13 gigs)
  3. My audio won't sync (status bar shows 5.4 gigs)
  4. Apps' don't show up under the status bar unless I hit the sync button and then they show up and then disappear. They are on iPad.
  5. I get a yellow bar with designated as "Other" that take up about 8.8 gigs

Any ideas how to fix this problem or what that code is?

A couple things that I should mention:

The "Other" 8.8 gigs on iTunes display mirrors that Settings > General > Usage > section.

Any help would be greatly appreciated.

iPad 2, iOS 6

Solved it! The move to new iTunes and new IOS clearly has a few settling issues.

Steps needed:

1. Sign-out of iTunes Store

2. Disconnect iPhone and switch off 'sync over wifi'

3. Close iTunes

4. Shutdown and cold re-start computer

5. Start iTunes

6. Dock iPhone and allow sync to take as long as needed (10 mins+ for me)

7. Force new sync and watch steps flow through

8. Sign-in to iTunes Store

I tried it and it didn't work. Is there any other suggestions? I'm trying to sync movies onto my i-pod touch, i've tried everything rom restoring my i-pod, to changing my settings and nothing has worked. HELP, I'm getting a tad bit tiresome of this situation.

In the absence of any other suggestion I upgraded to Mountain Lion form Lion and the problem disappeared. I can't help feeling that such solutions reek of deliberate corruption or neglect of software in order to provide revenue. I am a little cynical for an Apple "true believer" but I have been using Apple products almost exclusively since the eighties. It is not the first time that I have had this feeling and I guess it will happen again. My failth is not without it's limits.

I will up my antidepressants to solve the human problem so then eveyone will be happy. 😉
