With FAT32 format at least 2 reserved sectors are needed, the default is 32. Otherwise the default is 1 (only the boot sector). Note that this is minimal number and it may be increased by mkfs.fat due to alignment of structures. See also mkfs.fat option -a. Hello Bill,

sudo mkdosfs -R 1 -F 16 -a /dev/sda1

The -a enforces it since:
-R NUMBER-OF-RESERVED-SECTORS
Select the minimal number of reserved sectors. With FAT32
format at least 2 reserved sectors are needed, the default is
32. Otherwise the default is 1 (only the boot sector). Note
that this is minimal number and it may be increased by
mkfs.fat due to alignment of structures. See also mkfs.fat
option -a.

Specify -a. There's also a -v (verbose) flag that will print out all the parameters as it creates the filesystem to make sure it did it right.
