Table 196 Crypto Scramble Ext Command (B4h/0011h)
The CRYPTO SCRAMBLE EXT command supports an encryption model only.
The CRYPTO SCRAMBLE EXT command starts a crypto scramble operation (i.e., a sanitize operation that changes
the internal encryption keys that are used for user data) causing the user data to become irretrievable.
The CRYPTO SCRAMBLE EXT command only is reported as supported if all user data is affected by changing
internal encryption keys.
After a successful crypto scramble operation, the contents of the user data area may be indeterminate.
The CRYPTO SCRAMBLE EXT command only is processed if:
a) the Sanitize Device feature set is supported
b) the device is in the SD0: Sanitize Idle state, the SD3: Sanitize Operation Failed state, or the SD4: Sanitize
Operation Succeeded state.
