Head Flying Hours / Transfer Error Rate (Fujitsu) S.M.A.R.T. parameter indicates time spent during the positioning of the drive heads.
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.
