SSD not showing on laptop

Hi guys a little help here, got the new prime 2 I’ve just install a new WD 500gb ssd format in Exfat MBR but when I try to connect the Mac laptop it’s shows the screen of computer mode and nothing else happens it does show the ssd drive in the laptop. I’ve tried with a windows computer as well. i cant figure it out and its frustrating if i connect the ssd directly to the laptop its shows the ssd which i format and rename to “prime 2”, once i put it in the Denon prime 2 connect everything turn on, change to computer mode and nothing show on the laptop … strange but im out of ideias and now i have to play using usb only. thanks in advance

I’m having same problem, I’m wondering if it’s deck. I gotta try to hook ssd to computer.
