摘要： An apparatus, system, and method are disclosed for implementing protected partitions in storage media. The apparatus includes a control module configured to communicate with a host and receive read/write commands for a storage device, and a protection module operating within the control module and configured to maintain a plurality of protection states for the partition and a plurality of allowable transitions between the protection states. The system includes the apparatus, a host device, and a storage device coupled with the host, the storage device including an enclosure having storage media and a control module. The method includes communicating with a host device and receiving read and write commands for a storage device having at least one partition, and maintaining a plurality of protection states for the partition and a plurality of allowable transitions between the protection states on a control module located within the storage device.
