硬盘修复软件原理是什么？ddrescue、mhdd、hds用哪个？
硬盘修复软件原理是什么？开源的ddrescue能超越大家熟知的mhdd、hds之类的么？如题，希捷机械盘C5 C6出现黄色警告
不知还能修复不，想找软件试试，但原理是什么？
开源的ddrescue国内很少讨论，不知道效果咋样？
能超越大家熟知的mhdd、hds之类的么？还是说mhdd、hds有啥“魔法”非公开黑科技之类的？比开源的还好？
这是crystal disk info的smart

绝大多数硬盘修复软件的工作原理都是加入G表+写0,能加P表的修复软件非常少,这个DDrescue看了一下也就是G表.
能解决的C5 C6直接点掉快速格式化就行，解决不了的你上什么工具都没用
这种情况你只需要知道它在哪儿，别去想怎么修复

大概已经知道在哪了，该怎么办？
4T的盘，读取数据到3.2T左右出的这个
这个位置真尴尬。。。。。。。。。物理的直接换盘，逻辑的把那个分区格式化了或者用软件直接指定那个位置做擦除、重映射等。
你干脆直接丢掉最后1T完了 C5 C6全盘格式化一下试试。 概念有问题，mhdd、hds什么时候是硬盘修复软件了，只是检测软件、监控软件。 常用的修复工具只有hddreg。中文名硬盘再生器
原理是坏道加表映射。效果很好而且无损数据
基本碰到简单的坏道问题我就拿这个跑一遍，就能正常开机进去救数据了 overthink 发表于 2017-1-27 22:53
C5 C6全盘格式化一下试试。
用hard disk sentinel重新初始化磁盘表面，三遍C5 C6归零了。。
不过表面测试图有个非常深色的绿块
到底是什么原理这么神奇？。。
上次碰到C5 C6是用linux 下dd命令克隆磁盘的时候出来的，是不是linux读写磁盘能力不如windows? 真正的C5应该转05，也就是坏区+G表并启用备用扇区
处理后C5消失的有两种可能，一是逻辑问题，真的消失了，可能是弱扇区；二是还会复发，取决于有没有读写到那个区域，要是真有问题，小容量的盘三两下就复现了 merrykid 发表于 2017-1-29 05:31

弱扇区吧。 随时查看SMART吧，我有块WD的就是先出C5 C6，然后就挂掉了。
