f) READ LOG EXT command requesting one of the following log addresses:
A) E0h;
B) 30h; or
C) 10h;
g) READ LOG DMA EXT command requesting one of the following log addresses:
A) E0h;
B) 30h; or
C) 10h;
h) SMART RETURN STATUS command; or
i) SET FEATURES PUIS feature set device spin-up subcommand;
j) SANITIZE ANTIFREEZE LOCK EXT command;
k) SECURITY UNLOCK command;
l) supported sanitize operations commands, if the device is in the SD3: Sanitize Operation Failed state (see
Section 10.20.3.4) or the SD4: Sanitize Operation Succeeded state (see Section 10.20.3.5).
If the device processes an IDLE IMMEDIATE command with UNLOAD that returns command completion without
error, then the sanitize operation shall be suspended. The sanitize operation shall be resumed after the processing
of a software reset, a hardware reset, or any new command except IDLE IMMEDIATE command with UNLOAD.
If the device processes a power-on reset and enters the PM5: PUIS and spin-up subcommand not supported state
(see Figure 12), then the device shall resume processing the sanitize operation after receiving a media access
command, even though the media access command returns command aborted.
The SANITIZE STATUS EXT command returns information about the current sanitize operation, if any, including a
percentage of completion if a sanitize operation is in progress.
A CRYPTO SCRAMBLE EXT command (data encryption model only) or OVERWRITE EXT command that returns
command completion with no error transitions the device into the SD2: Sanitize Operation state. The device remains
in this state until the device has completed the sanitize operation (see Figure 12).
The SANITIZE FREEZE LOCK EXT command causes the device to transition to the SD1: Sanitize Frozen state and
causes any subsequent CRYPTO SCRAMBLE EXT command (data encryption model only) or OVERWRITE EXT
command to be aborted. If the device processes a power-on reset or a hardware reset, then the device transitions
from the Sanitize Frozen state to the Sanitize Idle state.
The crypto scramble operation makes previously written contents in the user data area irretrievable. (data encryption
model only)
The overwrite operation fills all user data with a four byte pattern passed within the LBA field of the command.
Parameters for the OVERWRITE EXT command include a count for multiple overwrites and the option to invert the
four byte pattern between consecutive overwrite passes.
A software reset does not cause the SD2: Sanitize Operation state to transition to another state.
