50 Typical reasons for an error here include:
51 * The parent directory does not exist, cannot be created, or disallows writing.
52 * The persistent store is not accessible, due to permissions or data protection when the device is locked.
53 * The device is out of space.
54 * The store could not be migrated to the current model version.
55 Check the error message to determine what the actual problem was.
