I had this USB for a year now everything worked fine, after my party i want to play the songs used in the party so i played some but when i played a song it became "Not Responding" and when i went to my USB it had no files and when i go to Computer i saw that the Space Bar showing the Space of my USB was replaced by saying "FAT32" i really need to fix my USB to listen to songs im working on how do i fix this problem?
