As I remember: It needs a large amount of time to calculate the free space on
a big FAT32 system. So the last free sector count is also stored. When
mounting this filesystem you don't need to walk through the whole FAT to
calculate the available space, you can use this "cached" value instead. And
this cached value seems not to be updated in your portable device.

Maybe it helps, but maybe I'm wrong.
