Abstract: A system for verifying the secure erase of a storage device is provided. A storage device controller for the storage device logs the execution of a secure erase command. A storage device controller for the storage device receives an erase verify command from a host. The storage device controller retrieves one or more secure erase log entries from access-limited memory locations in non-volatile memory of the storage device. The storage device controller copies the one or more secure erase log entries to storage device buffer circuitry. The storage device controller secures the one or more secure erase log entries with one or more cryptographic keys to generate an encrypted and/or signed erase verification message. The storage device controller transmits the encrypted and/or signed erase verification message to the host, in response to receipt of the erase verify command.
