굉장히 자세하게 소개해 놓았네요. ^^

----------------

I wrote this a while back and never finished it. later I figured people maybe interested. fat16 is old I know, but is similar in structure to fat32 and fat12 (floppy disk). this article is about fat16 with additional comments regarding windows 98. certain things will appear/handle differently in other oses.

special thanks go to jon fox who helped me out on calculating the hdd serial number, the lfn checksum and making some worthy comments while in draft form, I really appreciate it.
