Hi,
I create a 256MB partition on hard disk. The format it to FAT32, with 4096 cluster size.
THen I check the Boot sector of the partition, and find the the following parameters:
Sector count: 530145
Reversed Area Size: 38
FAT Count: 2
FAT Size: 517
Sector per Cluster: 8
In such a case, (530145 - 38 - 517 * 2) is not a multiply of 8 sectors. Is that correct for a FAT32 partition?

NTFS also has an extra sector, at least for MBR partitions.
https://thestarman.pcministry.com/asm/mbr/NTFSBR.htm"Total Sectors (in the Volume) will always be 1 sector less than the total number of sectors in the volume's partition table entry, because the NTFS "Backup Boot Sector" is not considered part of the NTFS Volume."
