I have the original iPad and a couple months ago I started receiving an error when trying to sync. The iPad begins the backup but I receive an error on Step 4 saying that the iPad cannot save the backup to the computer. I can sync things to the iPad but the backup is not being done. Now I have an update and I can't update the IPad because the backup cannot be complted. I have searched for others who have had similar problems and have deleted previous backup deleted apps and reinstalled deleted movies and reinstalled deleted iTunes and reinstalled Any suggestions?
