Had moments of worry this morning trying to sync and install an app on the iPad. iTunes first reported an unknown error -35, then told me that ‘the required disk was not found’.
How to solve “required disk cannot be found”:
He had me do the following:
1. go to home folder in finder
2. open pictures folder
3. right click on iphoto library and click on show package contents
4. Find “ipod photo cache” file and drag to desktop
5. Close finder
6. Reopen itunes and sync ipad
7. The ipod photo cache rebuilds itself

Unknown error -35 was solved by plugging in the iPad cable to the actual computer. It was originally connected to the corded Apple keyboard. Apparently not enough juice flowing through the keyboard to support the iPad.
Lessons learned.
