12) Provide as much detail of the issue here: I have recently moved to USB and rekordbox from Traktor, and was exporting roughly 25gb of analysed tracks onto my USB, which took a fair amount of time. When I went to put my USB into my cdj900, it says no USB. It is formatted to FAT32, so it shouldn't be that causing the problem. When I plugged the USB back into my Macbook, the tracks are on the USB, but the menu/sort information is completely blank.
