Flying Height S.M.A.R.T. parameter indicates the height of heads above the disk surface. The low value of this parameter increases the chances of a head crash while a flying height that is too high increases the chances of a read/write error.
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.
