External Hard drives wont show up on my hackintosh

Hey, so this is a problem ive been having for a few weeks now and i cant seem to find a fix for it.

I have mac os high sierra 10.13.4

3.7ghz intel 8700k

16 gb RAM

Nvidia gtx 970

Everything is working fine other then this issue. Usb sticks work fine but i cannot even see the external drive in the disk utility when i select show all. Also have tried resetting NVRAM, restarting the xomputer and just bought a brand new external. I have tried several and none work. Also tried different USBs and none work.

The drive is an Adata HD650

Anyone have any ideas on how to fix this issue?

Thanks!
