Seek Error Rate S.M.A.R.T. parameter indicates a rate of seek errors of the magnetic heads. In case of a failure in the mechanical positioning system, a servo damage or a thermal widening of the hard disk, seek errors arise.
Although this parameter is not considered critical by the most hardware vendors, degradation of this parameter may indicate electromechanical problems of the disk. Regular backup is recommended. If no other (critical) parameters report a problem, hardware replacement is recommended on mission critical systems only.
