Filesystem
============

Sector = 512 Bytes
Block  = 4096 Bytes

Reserved sectors
----------------
* Sector 0..7 - Bootblock, constains bootloader code that gets ran by the BIOS   (4KiB)
* Sector 8..F - Superblock, contains metadata about the filesystem itself        (4KiB)

Superblock structure (4096B)
--------------------
* Device ID
* Max File Size
* INode Count
* INode Bitmap Block
* INodes Start
* INode Block Count
* INodes per sector
* Data Bitmap Block
* Data Start
* Data Block Count
* Root INode Pointer
* First Unreserved INode

INode structure (64B)
---------------
* Type
* Size (bytes)
* Sector Count (size in sectors)
* Mode
* Extent[4]
* Single Indirect
* Double Indirect?

Extent (8B)
------
* Block
* Length
 
Directory Entry (64B)
---------------
* INode Number
* Name (max length 60 Bytes)

Filetypes
---------
* File
* Directory
# TODO
