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
65,536 (10000h) as its denominator
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) specified the
FAILURE MODE bit cleared to zero; and
c) a CRYPTO SCRAMPLE EXT command with the FAILURE MODE bit set to one is received.
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

Overwrite Ext Command (feature: 0014h)
The OVERWRITE EXT command starts an overwrite sanitize operation (i.e., a sanitize operation to overwrite the
internal media with a constant value) that fills physical sectors within the Sanitize operation scope with a four byte
pattern specified by the OVERWRITE PATTERN field of the command.
The host also specifies a count for multiple overwrites and whether to invert the four byte pattern between consecutive
overwrite passes.
After a successful overwrite sanitize operation, affected data blocks shall be readable without error.
