Description

Power-Off Retract Cycle S.M.A.R.T. parameter indicates a number of times the head was retracted as a result of power loss.

Recommendations

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.
