从映像中恢复 NTFS 文件系统

  • 772

我有一个 WD Passport 1TB 外置硬盘驱动器，ddrescue 在驱动器完全停止读取之前设法保存了 95%。

ddrescueview

恢复的数据存储为recovery.img.

$ mmls recovery.img 
DOS Partition Table
Offset Sector: 0
Units are in 512-byte sectors

      Slot      Start        End          Length       Description
000:  Meta      0000000000   0000000000   0000000001   Primary Table (#0)
001:  -------   0000000000   0000002047   0000002048   Unallocated
002:  000:000   0000002048   1953458175   1953456128   NTFS / exFAT (0x07)

但是我无法将图像挂载为 NTFS：

$ sudo mount -t ntfs recovery.img /mnt
NTFS signature is missing.
Failed to mount '/dev/loop11': Invalid argument
The device '/dev/loop11' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

$ sudo ntfsfix recovery.img
Mounting volume... NTFS signature is missing.
FAILED
Attempting to correct errors... NTFS signature is missing.
FAILED
Failed to startup volume: Invalid argument
NTFS signature is missing.
Trying the alternate boot sector
Unrecoverable error
Volume is corrupt. You should run chkdsk.

chkdsk recovery.img在我的 Windows 机器上说文件名无效。

我还尝试使用Ubuntu DataRecovery 文档中描述的偏移量（2048 * 512）：

$ sudo mount -t ntfs -o loop,force,offset=1048576 recovery.img /mnt
Failed to read last sector (1953456126): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
   or it was not setup correctly (e.g. by not using mdadm --build ...),
   or a wrong device is tried to be mounted,
   or the partition table is corrupt (partition is smaller than NTFS),
   or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/loop11': Invalid argument
The device '/dev/loop11' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

testdisk[ List ]文件确实有效，所以我会尝试从那里复制。但如果可能的话，我想安装。

关于我现在应该尝试什么的任何想法？

编辑：kpartx 的结果，使用此处列出的说明：

$ sudo kpartx -l recovery.img
loop11p1 : 0 1953456128 /dev/loop11 2048
$ sudo kpartx -a recovery.img
device-mapper: resume ioctl on loop11p1  failed: Invalid argument
create/reload failed on loop11p1
mount disk-image ntfs hard-drive ddrescue

    我最终只使用 testdisk 来列出和复制磁盘映像的全部内容。我很幸运，似乎我的所有文件都已保存（没有一个文件位于错误读取区域）。
