A long overdue response for @RNDM > Yes, that should work provided the enclosure's host chipset is compatible with Pioneer DJ products.
@Pablo > It could be the enclosure has the issue.
Pioneer DJ does not guarantee 100% compatibility with any USB drive (or enclosure). Functionality of one drive does not guarantee functionality of another identical make / model drive. Manufacturers are known to change the memory controller chip per availability or cost, and as a result, there is always a chance that a drive may not be compatible with the player host chipset. Recommendations or the results of another user may not be the same for you and your drive.
