Hello,
File Allocation Tables
The structure that gives the FAT file system its name is the file allocation table. In order to understand what this important table does, you must first understand how space on the hard disk is allocated under operating systems that use FAT family file systems (including DOS and most versions of Windows.)
Data is stored in individual 512-byte sectors on the hard disk. In theory, it is possible for each file to be allocated to a number of individual sectors, and this is in fact done for some file systems (such as HPFS.) However, for performance reasons, individual sectors are not allocated to files in the FAT system. The reason is that it would take a lot of overhead (time and space) to keep track of pieces of files that were this small: a 10 GB disk partition has 20,000,000 sectors! The hard disk is instead broken into larger pieces called clusters, or alternatively, allocation units. Each cluster contains a number of sectors. Typically, clusters range in size from 2,048 bytes to 32,768 bytes, which corresponds to 4 to 64 sectors each.
Edit: You can always learn more about FAT by doing a search on Google for "File Allocation Tables"

Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.
It is obious I will talk about File Allocation Table in this board

Check the OS-dev board - check the sticky at the top - lots of OS-dev links including some very good ones that explain FAT12, 16, and 32 in great detail.
Because you're too stupid to use Google, or what?Originally Posted by cfrost
