AirPort Extreme disc

Hi, I Have moved my music files to a disc attached to my AirPort Extreme. Can anyone tell me what options I need to get this to mount? In another distribution I have to enter sec=ntlm, but this doesn’t seem to worm with Volumio.

Ignore previous. Sorted with ro,sec=ntlm.

I tried several times, but it only saved and mounted after a reboot.

Thanks, we’ll add it to the user manual!
