我有一个几乎全新的西部数据绿能，但保修期已过。它被放在架子上。
我想在使用之前测试一下。
我做的第一步是使用数据救生员工具. 此测试给出错误
0226 Sector Relocation Error
这官方推荐是更换硬盘。但是很明显，供应商的动机是销售更多的硬盘。
SMART 状态显示没有重新映射，所以我不知道这里的错误是什么。我想知道是否有办法重新映射有问题的扇区？

答案1
您所参考的 WD 网页对错误 226 的含义说明得非常清楚：
226 扇区重新定位错误
驱动器修复期间无法重新定位扇区。必须更换驱动器。
所有磁盘都有一个小型扇区池back-up，用于在 HDD 使用寿命的两个不同阶段替换坏扇区，首先是在制造期间，然后是在正常磁盘操作期间。当发现坏扇区时，它会被标记为有缺陷并因此停用，并用备用池中的功能扇区替换。此时，备用池扇区将按re-mapped逻辑顺序出现在与停用扇区完全相同的位置。
值得一提的是，这些缺陷甚至在制造过程完成后立即出现，而这些恢复机制的有效性恰恰证明了我们大多数人根本不知道缺陷的存在和恢复策略。换句话说，我们所有人一直都在使用部分有缺陷的磁盘。
然而，在某个时候，备用池会耗尽，无法进行重新定位或重新映射。发生这种情况时，将发生数据丢失。如果关键位置的扇区发生故障（任何 HDD 上都有链接列表），整个磁盘上的大部分（如果不是全部）数据实际上都会丢失，或者可能只需要付出一些努力才能恢复。无论如何，即使故障没有发生在关键扇区，也会导致某种数据丢失。
这就是为什么 WD 建议更换磁盘是合理的；您的磁盘仍然可以正常使用，但目前还不行。制造商的信息基本上是一个you have been warned信号。
答案2
您应该尝试缩小分区，并确定是否必须在分区的开头或结尾处这样做。这是为了避免无法用备份扇区（不存在）替换的坏扇区。
