=== Dump Hardware Block (`DMP*`)

This block defines the set of hardware components involved in capturing the media content.
It includes an array listing each device used during the dumping process, along with the specific extents each device recorded.

This structure allows implementations to trace data provenance and associate dumped regions with their corresponding hardware sources, ensuring accountability and reproducibility in the dumping workflow.

==== Structure Definition

[source,c]
/**Dump hardware block, contains a list of hardware used to dump the media on this image */
typedef struct DumpHardwareHeader
{
    /**Identifier, <see cref="BlockType.DumpHardwareBlock" /> */
    uint32_t identifier;
    /**How many entries follow this header */
    uint16_t entries;
    /**Size of the whole block, not including this header, in uint8_ts */
    uint32_t length;
    /**CRC64-ECMA of the block */
    uint64_t crc64;
} DumpHardwareHeader;
