The invention discloses a physical address mapping method and component and a data processing method and component in the technical field of computers. According to the method and the device, the PMA length can be adaptively expanded for the high-capacity hard disk, so that the expanded available PMA length can meet the physical addressing range of the high-capacity hard disk, the expanded available PMA length can complete physical address mapping and addressing of the hard disk with the capacity larger than 8TB, and the physical addressing range of the PMA is expanded. On the basis of large-range physical addressing, the data read-write efficiency of the hard disk can also be improved. Correspondingly, the invention provides a physical address mapping component and a data processing method and component, which also have the above technical effects. 本申请公开了计算机技术领域内的一种物理地址映射方法及组件，数据处理方法及组件。本申请针对大容量硬盘，可以适应性为其扩充PMA长度，使得扩充得到的可用PMA长度能够满足大容量硬盘的物理寻址范围，因此扩充得到的可用PMA长度可以完成大于8TB容量的硬盘的物理地址映射及寻址，扩大了PMA的物理寻址范围。在大范围物理寻址的基础上，
