12.38 Sanitize Device Feature Set (B4h)
The Sanitize Device feature set allows the host to request that the device modifies the content of all user data areas
in a way that results in previously existing data to become unretrievable. Sanitize operations are initiated using one
of the sanitize operation commands.

The element identifier field specifies the storage element to be depopulated. If the element identifier field specifies an
element that is not a storage element (i.e., the PHYSICAL ELEMENT TYPE field (see Section 12.10.6.7.4) is not set
to 01h in the corresponding physical element status descriptor) or specifies an element not supported by the device,
then the device shall return command aborted with sense key set to ILLEGAL REQUEST and the additional sense
code set to INVALID FIELD IN CDB.

operations. This includes:

c) if an unsupported sanitize device command was received.
The SANITIZE STATUS EXT command is valid in every state of the Sanitize Device state machine.

After the sanitize operation has completed, if any physical sector that is available to be allocated for user data was
not successfully sanitized, then this command returns the ABORT bit set to one.
