Temperature Difference from 100 (Airflow Temperature) S.M.A.R.T. parameter indicates the temperature of the air inside the Seagate and Samsung hard disk housing. The value is equal to [100 – specified by manufacturer temperature °C], which allows setting the minimum threshold.


This parameter is considered informational by the most hardware vendors. Although degradation of this parameter can be an indicator of drive aging and/or potential electromechanical problems, it does not directly indicate imminent drive failure. Regular backup is recommended. Pay closer attention to other parameters and overall drive health.
