How to partition an external hard drive on mac for cdjs after catalina?

So I previously got this to work 2 years ago but now I had to reformat my external hard drive as it got corrupted.

I partition the drive to MS-Dot on mac which puts it to MSdot-fat32 and it shows up on recordbox. I put a couple of tracks in and on the cdjs it says it needs to be formatted. So I try doing an erasing msdot-fat32 partition and I get the same problem.

Is there a solution for this or am I back to the usbs...? :(
