reserved: u32le

must be 0

current_lba: u64le

For main header, 1

backup_lba: u64le

LBA for backup header

first_usable: u64le

First usable LBA for partitions (primary table last LBA + 1)

last_usable: u64le

Last usable LBA (secondary partition table first LBA - 1)

disk_guid: Uuid

UUID of the disk

part_start_lba: u64le

Starting LBA of partition entries

num_parts: u32le

Number of partition entries

part_size: u32le

Size of a partition entry, usually 128

part_table_crc32: u32le

CRC32 of the partition table
