I used the fatgen103.pdf doc to create FAT12 and FAT16 files on MMC cards
with a PIC.  You need to read the document carefully and don't assume
anything.

Also helpful is a disk viewer to see what you have on the card before and
after you let the PIC do its stuff.  I used WinHex disk viewer.

Good luck.
