умный Raw_Read_Error_Rate

Нужны мнения экспертов. Есть диск. Вот умный вывод Seagate «Семейство Barracuda 7200.10»:

Raw_Read_Error_Rate = 0 & Hardware_ECC_Recovered = 6 ... как это возможно?

И я читал, что Raw_Read_Error_Rate на Seagates всегда имеет большое значение ... верно? Это нормально?

Диск новый ... но Raw_Read_Error_Rate поднимается .. примерно + 2 / + 3 в час ... Что это значит? Нет большой нагрузки на IO ... там 200 сайтов ... WA в топе меньше 1% ...
