Data storage device, system, and method for restricting host access to only one portion of a data storage device includes a storage device having a user space including a plurality of sectors and a plurality of host access spaces each including a corresponding plurality of portions of the plurality of sectors wherein only one of the plurality of host access spaces is accessible at any one time to a host device. A switch selects one of the host access spaces as the active host access space. The method restricts host access to only a portion of a data storage device by dividing a user space on the data storage device into a plurality of host access spaces, selecting one of the plurality of host access spaces as an active host access space, and restricting access by the host device to only the active host access space.
