Queries reg USB MSC File System Emulation

Hi

I use MSP430 F series MCU.

I have to configure my nand flash memory (not the internal one ), that is interfaced to the MCU in Fat16 format .

I am using the USB sample code .

 

Here are my questions .

1. The File System Emulation code uses LBA 0 , 39 , 43 , 285 , 527 for MBR , Partition Block , File Allocation Tables and Root directory .

What is the significance of the LBA numbers  ?

2. why are they not stored sequentially in LBA 0 , 1 , 2 , 3, 4 .

3. Why does the data section start in LBA number 559 ?

4. Is the internal flash already programmed to exhibit itself as a FAT16 formated device ?

Thanks

Jenitta
