A bit off-topic, but since you took interest in the file system inner working, you might be interested in taking a look at an older project of mine:

http://hpgcc3.org/projects/cleanfs

It's a file system that does everything FAT does but without a FAT table: all information about a file is stored in the directory. It saves a LOT of I/O compared to FAT.
It has other good qualities:
* Unlimited length file names (UTF-8)
* On-disk format much simpler than FAT, easier for embedded systems to use.
* 64-bit file sizes
* The file system is self-contained: each directory is a file system on its own.
* It's well suited to be used for example for TAR or ZIP style archives, as well as block devices.
* Can be case-sensitive or insensitive, this is a run-time choice.

I never used it for anything serious, it was just a proof of concept, but the demo of the reference implementation works quite well.
