[fat] use ms-sys' partition_info source to correct Disk Drive ID
[fat] use ms-sys' partition_info source to correct Disk Drive ID
* Disk Drive ID fixup for FAT32 was already available in ms-sys with option -p * modified code to add FAT16 as well as FAT32 support as well as minor fixes * reverts previous patch write_fat_32_br() and write_fat_16_br()iso
