搞不懂的是这个绿块的定义哪来的?有多少实验数据说明这样定义是准确的?这个软件的作者也没说绿块多少代表硬盘就fail了,找了半天FAQ才看到这么一句:
Q: What is the meaning of scan results?
A: Normally, you should not get brown and red blocks. If you have some, see Q above (about erase delays). If you have blocks marked as a letter ("A", "x", "S", "!" and so on) — those are bad blocks. If there is more than 20% of surface is covered with bad blocks, then it is a head crash.

这样理解的话就是正常情况下,棕色和红色块应为0,绿块就没提。软件检测和HDtune一样,不是百分百的预测硬盘的好坏的,只是预测硬盘机械部件那部分,MHDD原文(This software can make precise diagnostic of the mechanical part of a drive),这个概率有多准?60~70%就很NB了,硬盘好坏不只机械部分,我的理解就是这样了,检测结果可以参考,要换也以官方测试软件为准。
