sectors are divided according to disk partitions, for example, ABCD disk, A disk sector starts from 0 bytes, to the number of bytes of A disk size, B disk is from A disk maximum number of bytes + 1, to A disk maximum number of bytes + B disk size bytes, and so on. Of course, the MBR partition is different from the GPT partition. There is a recovery partition in front of the GPT partition. Disk C does not start from 0, which can be seen in disk management.
