需要专家意见。有磁盘。以下是 Seagate“Barracuda 7200.10 系列”的智能输出：

“badblocks -wsvf /dev/sdb”之后智能输出是：

Raw_Read_Error_Rate = 0 & Hardware_ECC_Recovered = 6......这怎么可能呢？
我还读到 Seagates 上的 Raw_Read_Error_Rate 值一直很大...是这样吗？这样正常吗？
下一个磁盘是 Western Digital RE3 .. 320Gb ..这里很智能：

磁盘是新的……但是 Raw_Read_Error_Rate 却在增加……大约每小时 +2/+3……这是什么意思？IO 负载不大……有 200 个网站……顶部的 WA 不到 1%……
