[sprog](#sprog)

Sanitize Progress (SPROG): indicates the fraction complete of the sanitize operation. The value is a numerator of the fraction complete that has 65,536 (10000h) as its denominator. This value shall be set to FFFFh if the *sstat* field is not set to NVME\_SANITIZE\_SSTAT\_STATUS\_IN\_PROGRESS.

[sstat](#sstat)

Sanitize Status (SSTAT): indicates the status associated with the most recent sanitize operation. See *enum nvme\_sanitize\_sstat*.

[scdw10](#scdw10)

Sanitize Command Dword 10 Information (SCDW10): contains the value of the Command Dword 10 field of the Sanitize command that started the sanitize operation.

[eto](#eto)

Estimated Time For Overwrite: indicates the number of seconds required to complete an Overwrite sanitize operation with 16 passes in the background when the No-Deallocate Modifies Media After Sanitize field is not set to 10b. A value of 0h indicates that the sanitize operation is expected to be completed in the background when the Sanitize command that started that operation is completed. A value of FFFFFFFFh indicates that no time period is reported.

[etbe](#etbe)

Estimated Time For Block Erase: indicates the number of seconds required to complete a Block Erase sanitize operation in the background when the No-Deallocate Modifies Media After Sanitize field is not set to 10b. A value of 0h indicates that the sanitize operation is expected to be completed in the background when the Sanitize command that started that operation is completed. A value of FFFFFFFFh indicates that no time period is reported.

[etce](#etce)

Estimated Time For Crypto Erase: indicates the number of seconds required to complete a Crypto Erase sanitize operation in the background when the No-Deallocate Modifies Media After Sanitize field is not set to 10b. A value of 0h indicates that the sanitize operation is expected to be completed in the background when the Sanitize command that started that operation is completed. A value of FFFFFFFFh indicates that no time period is reported.

[etond](#etond)

Estimated Time For Overwrite With No-Deallocate Media Modification: indicates the number of seconds required to complete an Overwrite sanitize operation and the associated additional media modification after the Overwrite sanitize operation in the background when the No-Deallocate After Sanitize bit was set to 1 in the Sanitize command that requested the Overwrite sanitize operation; and the No-Deallocate Modifies Media After Sanitize field is set to 10b. A value of 0h indicates that the sanitize operation is expected to be completed in the background when the Sanitize command that started that operation is completed. A value of FFFFFFFFh indicates that no time period is reported.

[etbend](#etbend)

Estimated Time For Block Erase With No-Deallocate Media Modification: indicates the number of seconds required to complete a Block Erase sanitize operation and the associated additional media modification after the Block Erase sanitize operation in the background when the No-Deallocate After Sanitize bit was set to 1 in the Sanitize command that requested the Overwrite sanitize operation; and the No-Deallocate Modifies Media After Sanitize field is set to 10b. A value of 0h indicates that the sanitize operation is expected to be completed in the background when the Sanitize command that started that operation is completed. A value of FFFFFFFFh indicates that no time period is reported.

[etcend](#etcend)

Estimated Time For Crypto Erase With No-Deallocate Media Modification: indicates the number of seconds required to complete a Crypto Erase sanitize operation and the associated additional media modification after the Crypto Erase sanitize operation in the background when the No-Deallocate After Sanitize bit was set to 1 in the Sanitize command that requested the Overwrite sanitize operation; and the No-Deallocate Modifies Media After Sanitize field is set to 10b. A value of 0h indicates that the sanitize operation is expected to be completed in the background when the Sanitize command that started that operation is completed. A value of FFFFFFFFh indicates that no time period is reported.

[etpvds](#etpvds)

Estimated Time For Post-Verification Deallocation State: indicates the number of seconds required to deallocate all media allocated for user data after exiting the Media Verification state (i.e., the time difference between entering and exiting the Post-Verification Deallocation state), if that state is entered as part of the sanitize operation. A value of FFFFFFFFh indicates that no time period is reported.

[ssi](#ssi)

Sanitize State Information: indicate the state of the Sanitize Operation State Machine.
