尝试将我的 3TB HDD 克隆到全新的 4TB HDD。但我收到 CRC 错误
WDC WD30EZRX-00MMMB0 3TB
NTFS 文件系统
使用 Macrium Reflect 8 我得到
Clone failed - Error 9 - Read failed - 23 - Data error (cyclic redundancy check).
重要信息:
Current Pending Sector Count
Current 200
Worst 200
Raw values 000000000004
Off-Line Uncorrectable Sector Count
Current 200
Worst 200
Raw values 000000000003
所以我跑去看看这是否有帮助
CHKDSK /F /R 结果:

Checking file system on E:
The type of the file system is NTFS.
Chkdsk cannot run because the volume is in use by another
process. Chkdsk may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) Volume dismounted. All opened handles to this volume are now invalid.

我已经开始了使用 Teracopy 和散列和验证的漫长过程,将所有文件手动复制到外部硬盘上。
我的问题是 chkdsk 是否恢复了任何丢失的文件?我在任何地方都找不到任何“Found.000”文件夹或 .chk 文件。
下一步的最佳做法是什么?我是否应该尝试运行 Macrium Reflect Image 并忽略坏扇区,然后将该映像恢复到全新的 4TB HDD?(在启用忽略坏扇区设置的情况下运行克隆不起作用)如果我这样做,我会丢失坏扇区上的数据吗?
答案1
chkdsk 是否恢复了任何丢失的文件?
不,它所做的只是找到两个坏簇并将它们添加到坏簇列表中。幸运的是,这些簇正是阻止 Macrium Reflect 进行复制的簇。
相反,如果坏簇是某个文件或文件夹的一部分,并且其内容未能成功挽救,那么这些文件/文件夹现在可能会丢失部分数据。
答案2
我的问题是 chkdsk 是否恢复了任何丢失的文件?我在任何地方都找不到任何“Found.000”文件夹或 .chk 文件。
不,坏簇位于可用空间中。请参阅:

这就是我们进入意见领域的地方。
如果 Macrium 现在能够克隆驱动器,我会尝试一下。我不是这个工具的专家。如果是这样,您可以忘记 3 TB 驱动器,或者通过运行表面扫描(例如使用 HD Sentinel)来检查驱动器的更精确状态。
但是,即使 chkdsk 将簇映射到 $Badclus 文件,也并不意味着它们消失了。Chkdsk 只是确保 Windows 不再尝试使用它们。此外,如果 Macrium 是基于文件系统的,它现在应该会忽略这些簇。
理想情况下(在我看来),您可以让驱动器本身处理坏扇区。如果您拥有 HD Sentinel 的许可副本,那么您应该能够:
- 运行 ar/w 表面扫描
- 然后,驱动器要么确定这些扇区是好的,它将删除待处理标志,要么确定这些扇区是坏的,它们将被重新分配
- HD Sentinel 还能够判断文件是否受到坏扇区的影响以及哪些文件受到影响。
所以 ..
- 如果可能的话,让 Macrium 克隆驱动器(如果需要,忽略坏扇区设置)。理想情况下,您需要先克隆驱动器,然后再执行其他任何操作。
- 然后处理 3 TB 驱动器。您不希望出现这样的情况:诊断和“修复”驱动器导致驱动器出现故障,最终导致您无法进行克隆。
- 如果你发现根本无法克隆驱动器,那么你会发现自己救援领土。换句话说,您需要一个专门用于在克隆过程中处理坏扇区的工具。
