A problem by using HDD Expansion Board

I plan to use HDD expansion board link raspberry, used to store music.
The product model is X800, see the link below.

Have anyone used this before?

I got a problem by using the expansion board. When I plug in the SD card with new volumio system, I can see the “Volumio” AP connection and it works. But when I finish the configuring of the WiFi, restart the system, I can no longer link to the network. Then i remove the hard disk, it works.
I would like to ask what is the problem? what needs to be configured?

Thanks!
