Write Error Rate / Multi-Zone Error Rate (Western Digital) S.M.A.R.T. parameter indicates the total number of errors appearing while recording data to a hard disk. This may be caused by problems with disk surface or the read/write heads.
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.
