SOURCE: Moultrie MFH-DGS-200 .... says SD Card Locked on

I had the same problem with my game cam this year and after disassembling the camera and looking at the SD card assembly I fixed it using the following technique. My assumption is that the SD card assembly is poorly constructed and that the card is not making good contact with the contact springs inside the SD card connector.

1. I removed the sd card
2. I folded a piece of notebook paper so that it was about the width of the sd card slot and about as thick as 3 sheets of notebook paper.
3. I slid the folded paper into the SD card slot
4. With the paper still in the sd card slot, I slid in the SD card on top of it with the contacts facing up (the correct direction). This made the sd card fit much more snug in the slot.
5. I turned the camera on, and left the paper in the slot with the SD card.

The camera then recognized the SD card every time.

Hope this works for you too.
