Parse the EFI header shown in Figure 2 and complete the below table. Provide the signature and disk GUID as simple data structures. Parse the remaining items requested as little endian data structures. Is the partition table/array shown in Figure 2? If not, where on disk would you go (LBA) to find it? How big is each partition table entry in a 'GPT Disk'? Does this disk have a 'Protective MBR'? Briefly explain how you know. Compare and contrast MBR and GPT disk partition table entries.
Understand the Problem
The question is asking to analyze the EFI header from the provided image, specifically focusing on parsing the GPT signature, GUID, and various data fields such as header size and address locations. It requires completing a table with specific details from the header and answering related questions about partition sizes and types.
Answer
GPT Disk signature is 'EFI PART'; each partition entry is 128 bytes; Protective MBR exists.
The final answer is: The 'GPT Disk' signature is 'EFI PART'. The disk GUID is interpreted as bytes. Each partition table entry in a GPT disk is 128 bytes. The presence of a Protective MBR can be confirmed by reviewing the first sector. MBR uses a 32-bit system, while GPT uses 64-bit addressing, supports more partitions and includes redundancy.

More Information
MBR vs GPT: MBR can only handle disks up to 2TB with a maximum of 4 primary partitions. GPT supports large disks with many partitions and includes backup for corruption resistance.
Tips
Always verify endianness when parsing binary data.
