iTunes to iPad - An unknown error occurred (-50)

I saw this: -

An unknown error occurred (-50)

from an iPad Mini whilst trying to sync, via USB, from iTunes 11.3.1 on my Mac.

Thankfully, a few Google searches later, I performed the most minor of resets - General > Reset > Reset All Settings, which appears to have cleared the problem.

I did, it must be said, have an iTunes backup of the little fella, just in case :-)
