It looks like fat.c is not handling the case where the sectors/cluster is 1, and the rood directory spans multiple clusters.
In my case I was getting garbage directoy info after the invalid fat error. The attached patch stops the code from rolling past the end of cluster.
It looks like a loop to walk the allocation chain is neccessary. I think get_contents() does all the right work, but it of course starts with a directory entry, which we don't have yet for /. A little refactoring might do the trick.

FYI, my patch may have prevented walking off the end of a cluster on FAT32, but it has its own problems with larger directories on FAT16.
As such, I don't recommend using it.
