Understanding FAT16.. Help needed

Post by liak » Sat Jan 17, 2009 1:56 am

Dear All,

I have searched through the net in order to get an understanding of FAT16. Now I think I have gotten the main gist of the structure of FAT16 but a few things need clarification as I am still not able to grasp these

1. Size of FAT16 region,. In order for the FAT to allocate the addresses for all the clusters 16 bits will be used to allocate the addresses of all the clusters (right?). So I guess the FAT16 region would be 2 bytes * 2^16? about 128kb?

2. The content of the FAT16 is the address of the clusters in the file chain (either like a pointer or end of file)?

3. If I formatted a SD card in FAT16, and the card only contains 1 file, can I be sure that the entire file runs from clusters to clusters in a sequential manner without skipping or jumping?


Am I right in my understanding? If not can anyone please shed some light on me?

Thanks.
Regards,
Liak
