Q: attempting to copy to the disk failed. an unknown error occurred (-54) external drive

Starting this morning, I get this error when I sync my iPhone:

 

Attempting to copy to the disk 'Media' failed. an unknown error occurred (-54)

 

My iTunes media is stored on an external drive (called 'Media').  I have tried:

  • repairing disk permissions
  • repairing the disk 'Media' using Disk Utility
  • restarting the computer
  • doing a hard reset on my iPhone

 

There seem to be a lot of threads discussing this particular error, but I haven't seen any solutions that work for me.  Has anyone else had this problem and solved it?

 

Thanks!

iPhone 6, iOS 9.0.2
