Host Protected Areas

Note that many drives will contain a host protected area, which will not be displayed in the file explorer for an operating system. The MAX ADDRESS of a drive can be set so less than the full size of a drive is shown. The rest of the drive will be a host protected area, the OS cannot work with. But BIOS software may work with the host protected area. A host protected area may be required for some firmware because it cannot successfully boot from a large drive.
