Abstract:
A method of sanitizing a media comprising a controller and a storage device, the method comprising executing, by the controller, a command to erase a data area and an internal area of the storage device, verifying, by the controller, that at least a portion of the data area and at least a portion of the internal area of the storage device has been erased, generating, by the server, a certificate of media sanitization (CoS) of the media, and registering, by the server, an entry representative of the CoS of the media in a distributed ledger or database. Here the storage device is configured to store data received from a host external to the storage device only in the data area, and the storage device is configured to store operational data in the internal area for the operation of the storage device.
