Endian-ness in FAT32

Endian-ness is about byte ordering. We have two types: big endian and little endian.

Suppose we see the following, which represents the bytes per sector.

We have two ways to interpret this number, either 0x00 02 or 0x02 00

Big Endian

0x0002 = 2 bytes

Little Endian

0x0200 = 512 bytes

As in FAT32, little Endian is used. Therefore, the number of bytes per sector is 512 bytes.
