Print FAT table in a compact flash ??????????

Hi Im trying to access the FAT table in a compact flash. from what i have understood

i have got sandisk 256mb compact flash

compact flash memory starts with

- a boot sector of 512 bytes

- then FAT 1 of 512 bytes

- FAT 2

- Data

i want to print the FAT table

how iam i doing that is like this

Read a sector using LBA mode set command register to 0x20 and then i need to give LBA logical block address LBA usually starts from 0 so i assumed that LBA for FAT table is gonna be at address 1 so i gave LBA address as 1

this program is made of assumptions and the program is not working

CAN ANYONE TELL ME HOW TO PRINT THE FAT TABLE FROM MY COMPACT FLASH ???????????????

First off, you need to set the parameter registers (sector count, the the LBA registers (aka cylinder lo, cylinder hi and sector, and the drive/head register) BEFORE you issue the read sector command. The command uses the values present in the registers at the time the command is issued.

The location of the FAT table depends on the file system under which the CF was formatted. The FAT is not an inherent characteristic of a CF card, rather it is data written to the card when the card is formatted.
