Q: Attempting to copy to the disk Macintosh HD failed. An unknown error occurred (-54).

I am trying to sync my new iPhone 6S to iTunes via USB.  I keep getting this message: "Attempting to copy to the disk Macintosh HD failed. An unknown error occurred (-54)."  Can someone please help?  I've already repaired Disk Permissions via Disk Utility on my Mac and also Reset all Settings on my iPhone to no avail.
