I see the SD card recognized and enabled in Software - Mount Points

Since I put the router back to factory default I now have samba36-server

I have reformatted the SD card to NTFS, enabled in File Sharing LAN and Writable and tried the obvious different settings within Software - Mount Points - Edit, but i still cannot save to card and get message saying not enough memory on file system with code 255

My objective was to get more/better security on the router/network by installing packages, but if this is not possible to secure the router this way, I need to be looking at other options rather than trying to create additional memory that may not be so relevant at the moment
