Attempting to copy to the disk failed. An unknown error occured (-4)

I am simply trying to sync my son's iTouch with iTunes and I get the following error:

"Attempting to copy to the disk failed. An unknown error occured (-4)"

All my software (e.g.: iTunes) and the iOS is fully up-to-date.

iTunes (v.12.1.0.50)

OSX Yosemite Version 10.10.2 (14C109)

iPod touch, iOS 8.2
