Start from the beginning, and stop when you are done.

Seriously, IMHO the good question is not "how" but "why".

In any case, have a look first at http://en.wikipedia.org/wiki/File_system

There is various good literature on that.

But how about if you first tell us what need you feel to write a new file system, and what advantages it will have above other existing file systems?

I guess that if you want to write a file system from scratch you are looking towards thousands of men-hours of effort, so I am sure you want to explain us more than those 8 words you just posted.

There is a filesystem called the "Simple File-System" that is supposed to be even more simple than FAT. So look at that and see how it does what it should and how it keeps track of files and then apply the concepts in your own.
If working with C++ (My Reccomendation) get VERY well aquainted with fstream.

Just have a look to Dominic Gianpaolo's homepage, you'll find a link to a pdf file of the book and a link to the file system construction kit that you can download as well.
