Same problem here, driving me crazy because it's unpredictable. Last night I copied 500GB (movies 1-2 GB) from an old external HDD to a new external external HDD. Finished the next morning without problems. Next I wanted to copy 5GB and the transfer became slower until it came to a halt. The system (Ubuntu 14.04) froze, I could't use the mouse/keyboard. Had to reset my computer at the risk of damaging the disk. Luckily that didn't happen. Tried a couple times but the system kept on freezing. Had to use Windows to get the job done.
