I have a Smart B1 but I would think that the Max should handle sys memory the same way. It has been quite a while but as I recall I did not have any luck formatting my card with the PC either. I ended up deleting the partitions with the PC. Starting with a completely clean SD card, I used one of the DSFs to do the work on the Dune. You insert the clean SD, put the DSF on a USB memory stick (or HDD). You execute the DSF from the USB and it does the work. The description below was copied from the Dune Wiki that I linked in the earlier post.
Searches for a blank SD flash memory cards (without partitions or with a blank partition) size more than 2GB, and it creates two aligned sections, the first 2GB, second - for the rest of place. The first section is installed as a system drive. The second section is formatted in EXT3 with the standard cluster size.
