Abstract
A data storage device comprising a non-volatile storage medium configured to store user data, a data port configured to receive and transmit data between a host computer system and the data storage device, and a controller. The controller is configured to receive, via the data port, a write command comprising a read restriction indication, receive, via the data port, data and write the data to an address of the non-volatile storage medium. The controller is further configured to determine an occurrence of a read restriction event, and in response to the occurrence of the read restriction event and in response to the read restriction indication, erase the data from the address of the non-volatile storage medium.
