前天ovh独服看到197 Current_Pending_Sector 数值变成1，然后用badblock扫描坏道果然发现了4个，我也没继续修复。只是开始备份数据准备找客服换硬盘。
结果今天数据快拷完了重新检测了下发现smart 197又变成0了，重扫之前坏道的块也扫不到坏道了。这是怎么回事？

坏道是物理损坏，只能把这片区域屏蔽掉不用...不会消失

如果自己消失了你还敢用吗？

机械一般直接屏蔽那个坏道，你扫完他就当好了

c5 相当大一部分都是可以自动修复，但是我有时候备份数据后一般都是标准格式化一次，一般情况下会修复这种错误，如果标准格式化没有清除这种错误，那么很大概率就是物理坏道了

可以屏蔽继续用
