Hey guys, I have looked all over and cant figure out why a new sandisk ultra usb 3.0 128gb will not be read by my cdj-2000's with their latest fw offering. I can get songs on it via rekordbox but no matter what cdj i play on it wont read it and keeps giving me a format error even though it is set up as FAT32

Now sandisk refuses to send me a new one because they claim as long as it works with pc's or macs then it works. Has anyone else had this issue or know if there is a fix?
