• The MBR is comprised of a small section of operating system independent code, a disk signature, the partition table, and an MBR signature.
• The disk signature is a unique four-byte identifier for the hard drive.
• It is used for purposes such as identifying the boot volume and associating partitions and volumes with a specific drive.
