Error Output
The ABORT bit is set to one if a SANITIZE DEVICE FREEZE LOCK EXT command has successfully completed
since the last power-on reset.
The device returns command aborted if:
a) the device is in the SD3:Sanitize Operation Failed state
b) the completed sanitize command (i.e., CRYPTO SCRAMBLE EXT, or OVERWRITE EXT) contained the
FAILURE MODE bit cleared to zero
c) an OVERWRITE EXT command with the FAILURE MODE bit set to one is received.
Sector Number (HOB=0)
Invert pattern between overwrite operations
The FAILURE MODE
1: the device may exit the SD3: Sanitize Operation Failed state with
successful processing of a SANITIZE STATUS EXT command.
0: the SD3: Sanitize Operation Failed state returns command aborted for
sanitize operations with the FAILURE MODE bit set to one until the device
returns to the SD1: Sanitize Idle state.
OVERWRITE OPERATION COUNT
This specifies how many write operations occur in the overwrite operation. A
count of zero requests sixteen write operations.
OVERWRITE PATTERN (31:24)
The OVERWRITE PATTERN specifies a DWord pattern to be written across
each physical sector affected by this command.
OVERWRITE PATTERN (23:16). Ditto.
OVERWRITE PATTERN (15:8). Ditto.
OVERWRITE PATTERN (7:0). Ditto.
Sanitize Operation Completed Without Error.
1: the Sanitize Device state machine enters SD4: Sanitize Operation
Succeeded.
0: the Sanitize Device state machine enters SD2: Sanitize Operation. The
value of this bit is maintained across power-on resets.
Sanitize operation in progress
Device is in the SD1: Sanitize Frozen state
The Sanitize Progress Indication (15:8).
Progress indicator for the current sanitizes operation when the Sanitize Device
state machine is in the SD2: Sanitize Operation state. This value is FFFFh if the
Sanitize Device state machine is not in the
SD2: Sanitize Operation state (i.e., a sanitize operation is not in process). The
returned value is a numerator that has 65536 (10000h) as its denominator.
The Sanitize Progress Indication (7:0). Ditto.
Sanitize Device Error (7:0)
00h Reason not reported
01h Sanitize Command Unsuccessful. The sanitize operation completed with
physical sectors that are available to be allocated for user data that were
not successfully sanitized.
02h Invalid or unsupported Sanitize Device Feature Field Value
03h Device is in the Sanitize Frozen state
04h..FFh Reserved
