USB Flash Drive 3.0 Plays music fast forward in my car radio.

The audio files play perfectly when I play them from source i.e.  from the folder on my PC.   As soon as they are copied to the thumb drive they play fast forward (skipping) on any device I plug the thumb drive into.  If I transfer them to another thumb drive that ISNT a sandisk they play perfectly.  The problem is with the thumb drive NOT the files NOT the PC.
