Are you not looking at this problem from the wrong angle? Could it be nothing more simple than the track has been corrupted in some way? Just because the track has been fine for a long time does not mean that has not affected by something like micro-stutter or interference when you backed it up to your external hard drive. I would think the simplest method to resolve this problem would be to delete the track and replace if with a fresh copy.
