Problem - All in One Systems with 1tb SanDisk

 Can anyone explain/help me with this problem.

So I dj in lots of places all with different with set ups. I have Sandisk extreme pro USBs 250/500/1tb

When I use the 1tb with any controller rx3 /rx2/ rr/xz everything works fine as long as I don't plug in ANY other USB, as soon as I do, they all crash in one form or another, every time.

The Rx3 all playlists and artists disappear from the menu and I can't find any songs. Can freeze occasionally.

The rx2 and xz both say device library corrupted and eventually freezes

The rr just freezes instantly

Of course I have no problems with the cdjs I use.

These problems don't happen with the smaller USBs.

My theory is that it's just too much for the controllers to handle 1tb Usb (50000+ tracks) with another USB

Also when using the 1tb alone, when ejecting the usb it takes like15min+ for the red light to stop flashing.

(The usbs are fine btw, not corrupt, everything is exported correctly etc etc, )

Of course I can just use the smaller USBs but I am just trying to get to the bottom of this so any info would be great, thanks in advance🤙
