SSD 耗尽备用块后从 NTFS 恢复数据

SSD 耗尽备用块后从 NTFS 恢复数据

我的计算机的主 SSD 耗尽了备用块,因此拒绝 Windows 的任何/所有写入操作。这导致了您所期望的所有问题以及很多挫败感。

此后我更换了 SSD 并重新安装了 Windows,但现在我需要从该驱动器恢复数据。

驱动器可读 - 所有块均可读取。驱动器将拒绝写入操作。

我已将dd分区 ( /dev/sdb4) 中的所有 1.8 TB 存储到一个文件中,以便可以脱机工作。

但现在我需要恢复数据。

[root@VintageWarlord Temporary]# mount.ntfs-3g -o force,ro sdb4.image /mnt/test
$MFTMirr does not match $MFT (record 3).
Failed to mount '/home/christopher/Temporary/sdb4.image': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

(我尝试过mount.ntfs其他迭代也无济于事,并且在尝试直接从 SSD 挂载时遇到相同的错误)。

它真的非常不喜欢这个卷。 AFAIK 该卷未经过 Bitlocker 加密。

此时,我并不关心让该驱动器恢复运行,我只想要其中的数据。我可以做一些tar -xf sdb4.image .我绝对会做的事情。我没有 2TB 驱动器,我只能对其进行映像,然后运行 ​​ntfsfix,然后复制数据,但如果需要的话,我可以购买一个。

如何恢复这些数据(最好不购买硬件)?我有足够的存储空间来存储图像或图像的处理版本,但没有空闲的完整驱动器可以将dd数据返回。

答案1

我的建议是购买新磁盘。如果您愿意,可以选择旋转金属,但大约 3TB-4TB。首先,用它来ddrescue构建一个可以用Windows系统修正的磁盘映像。然后,完成此操作并检索丢失的数据后,将其重新用于定期备份。
