Disk Shift S.M.A.R.T. parameter indicates that a distance of the disk has shifted relative to the spindle, which could be caused by a mechanical shock or high temperature.


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.
