12.38.2 Crypto Scramble Ext Command (feature: 0011h)
The CRYPTO SCRAMBLE EXT command starts a crypto scramble sanitize operation (i.e., a sanitize operation that
changes the internal encryption keys that are used for user data) causing the user data to become unretrievable.
The CRYPTO SCRAMBLE EXT command shall only be reported as supported if all user data is affected by changing
internal encryption keys.
After a successful crypto scramble sanitize operation, the contents of the user data area may be indeterminate.
