Read Error Rate S.M.A.R.T. parameter indicates the rate of hardware read errors that occurred when reading data from a disk surface. Any value differing from zero means there is a problem with the disk surface, read/write heads (including crack on a head, broken head, head contamination, head resonance, bad connection to electronics module, handling damage). The higher parameter’s value is, the more the hard disk failure is possible.
This is a critical parameter. Degradation of this parameter may indicate imminent drive failure. Urgent data backup and hardware replacement is recommended.
