8.2.34.1Smart disable operations (D9h)

This command disables all SMART capabilities within the device including any timer and event count functions related to this feature. After receipt of this command the device shall disable all SMART operations. SMART data shall no longer be monitored or saved by the device. The state of SMART (either enabled or disabled) shall be preserved by the device across power cycles.

After receipt of this command by the device, all other SMART commands (including SMART DISABLE OPERATIONS commands), with the exception of SMART ENABLE OPERATIONS, are disabled and invalid and shall be command aborted by the device.

8.2.34.2Smart enable/disable attribute auto-save (D2h)

This command enables and disables the optional attribute auto-save feature of the device. Depending upon the implementation, this command may either allow the device, after some vendor specified event, to automatically save its updated attribute values to non-volatile memory; or this command may cause the auto- save feature to be disabled. The state of the attribute auto-save feature (either enabled or disabled), shall be preserved by the device across power cycles.

A value of zero written by the host into the device’s Sector Count register before issuing this command shall cause this feature to be disabled. Disabling this feature does not preclude the device from saving SMART data to non-volatile memory during some other normal operation such as during a power-on sequence or during an error recovery sequence.
