HYDRA SD MAX mystery

I ran the demo program that came with the SD MAX (sdmax_demo_001.spin). It mounted the SD card successfully, but the partition boot information is way off:
Looking a little closer, I discovered that the Master Boot Record (sector 0) on my SD card contains text ("Remove disks or other media...") starting around $1b0. So when the demo program looks for a partition entry at $1be, it finds junk.
Is there a form of Master Boot Record different from the one described in the SD MAX documentation?

fsrw handles this possibility, so I guess it's kosher, but is it documented anywhere that the MBR might not be there?
