I have a folder on a second internal HD that I share from my Mac mini (running 10.12). I usually connect to it through SMB, but I need to use AFP due to using an older Mac. However, I cannot get the folder to show up while connecting via AFP, it only shows via SMB. I have tested and found that any folder shared from my internal SSD/boot drive is accessible via AFP, but not any folders from my internal HD.
Any idea what's going on and how I can fix this?
