Description

G-Sense Error Rate (Shock Sense Error Rate for Hitachi) S.M.A.R.T. parameter indicates a number of errors resulting from shock or vibration.

Recommendations

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.
