Last weekend I had 2 major events with more then 40 djs playing with my Prime setup. We had only one small issue with file reading. One - exactly one dj came with some sort of corrupted file / files that froze the deck and caused it to do a core dump. After reset, we removed the usb stick and all was fine like nothing happened. I used my macbook to reformat the drive and put back his music on it. Unfortunately the problem was still there. One or more of his mp3’s were causing issues. Is there a way to check and eventually eliminate the faulty files from the usb? Any one had any more experience with such thing?
