A data storage device includes a disk and a plurality of actuators for reading and writing data on the disk in different physical realms. Each physical realm is associated with at least one logical zone domain including at least one logical zone. The at least one logical zone domain corresponds to an actuator of a plurality of actuators that accesses the physical realms associated with the at least one logical zone domain. In one aspect, reading and writing of data is enabled in one or more logical zones in response to a SATA zone activate command. In another aspect, a SATA read or write command is received indicating at least one logical address for data to read or written on the disk. Data is read or written in a physical realm using the actuator corresponding to a logical zone domain including the at least one logical address.

Data storage device configuration for accessing data in physical realms

Some of the embodiments disclosed are systems and methods of configuring an access masking structure which include, but are not limited to, selecting at least one computer to participate in an access restriction set, selecting at least one storage unit to participate in the access restriction set, disabling all non-selected computers, disabling all non-selected storage units and placing the access masking structure into learn mode. This method also comprises booting the computer, detecting activity between the selected computers and the selected storage units, and automatically building the access restriction set based upon the detected computers and storage units while the access masking structure is in the learn mode.
