如何从 FAT 映像恢复已删除的文件?
How to recover deleted file from FAT image?
我想知道如何从 FAT 中恢复已删除的文件。我创建了 fat.img 如下。
cd /tmp
dd if=/dev/zero of=fat.img bs=1024 count=100
mkfs.msdos fat.img
mkdir -p /tmp/fs
sudo mount -t msdos fat.img /tmp/fs -o umask=000,loop
现在我正在用一些文本创建文件。
cd/tmp/fs
echo "hello world"> name
使用 hexdump 查看它是如何保存的
cd ..
hexdump -C fat.img

这是我的问题,您有什么建议吗?我怎样才能将 fat.img 更改为 .AME 到 NAME 以恢复我的文件?
how can i change fat.img to .AME to NAME to recovery my file?
简短的回答是dd
,下面是一个带有必要注意事项的示例。
添加到 Martin 的答案中,同时操纵字节以恢复软盘映像中的文件是一个相对直接的命题 dd
,计算文件分配的位置和内容 table( s) 需要恢复是挑战。通过使用 dd
恢复文件本身,了解需要注意的字节如下例所示。
创建要使用的软盘映像使您不必在实际映像上进行试验。只需复制您希望使用的图像,或在硬盘驱动器上的文件中创建一个新图像。您可以使用 mkfs.msdos
轻松做到这一点(根据需要调整文件系统类型),然后按如下方式将文件挂载到您的文件系统中,例如
$ mkfs.msdos -C /home/david/tmp/tt/floppy_144.img 1440
$ sudo mount /home/david/tmp/tt/floppy_144.img /mnt/fd
现在让我们添加 NAME
文件:
$ echo "hello world" > NAME
$ sudo cp -a NAME /mnt/fd
$ ls -l /mnt/fd
total 1
-rwxr-xr-x 1 root root 12 Dec 17 13:55 NAME
$ cat /mnt/fd/NAME
hello world
在从您的图像中删除文件之前,对内容进行十六进制转储,以便您可以准确地看到需要恢复的内容。 (这是您必须计算的内容,以便了解要用原始图像恢复到哪里以及恢复什么,您将需要查阅相关文件系统的参考资料)
$ hexdump -C floppy_144.img >flpwname.txt
现在从您的图像中删除该文件并再次保存显示更改的 hexdump。
$ sudo rm /mnt/fd/NAME
$ hexdump -C floppy_144.img >flpwoname.txt
现在您可以检查与 diff
的区别。你发现你必须恢复的不仅仅是被删除文件的名字,你将需要恢复文件分配 table 条目,以便恢复的文件可以再次位于文件系统中(两个副本的脂肪),例如
$ diff flpwname.txt flpwoname.txt
16c16

注意上面的文件分配 table(s) 在 0x204
和 0x1404
的条目在文件被删除时被清零。使用 dd
可以轻松将字节恢复为原始字节,但 请注意您的选项 。具体来说,你的 block size
(bs
)、output block size
(obs
)、count
和 seek
都必须在 bytes
中(指定通过将 c
) 附加到数字,您必须设置 notrunc
转换选项以防止在您进行更改后截断图像。最后,必须在 decimal
而不是 hexadecimal
.
中指定所有尺寸
此外,如果您使用 bash,您可以使用进程重定向来指定要替换的字节(例如 if=<(printf "\xf0\xff")
写入十六进制字节 f0
和 ff
),否则,您将不得不准备包含替换字符串的输入文件。恢复 FAT 和文件名第一个字符的 dd
命令相当简单(有关选项说明,请参阅 man 1 dd
)。
下面我们恢复FAT的第一个副本,然后是第二个,最后恢复文件名的第一个字符。 seek
(偏移量)值只是由 hexdump
提供的转换为十进制的值。 (您应该在进行更改之前卸载您的文件系统。您可以在安装软盘映像时进行更改,但在您重新安装之前它们不会反映出来)
$ sudo umount /mnt/fd
$ dd if=<(printf "\xf0\xff") of=floppy_144.img \
bs=1c obs=1c count=2c seek=516c conv=notrunc
$ dd if=<(printf "\xf0\xff") of=floppy_144.img \
bs=1c obs=1c count=2c seek=5124c conv=notrunc
$ dd if=<(printf "N") of=floppy_144.img \
bs=1c obs=1c count=1c seek=9728c conv=notrunc
现在您可以创建修复后的软盘映像的 hexdump 并将其与原始文件进行比较。如果一切顺利,那就没有区别了。
$ hexdump -C floppy_144.img >flprepair.txt
$ diff flpwname.txt flprepair.txt
最后,只需重新挂载您的文件系统并确认文件已恢复。
$ sudo mount /home/david/tmp/tt/floppy_144.img /mnt/fd
$ ls -l /mnt/fd
total 1
-rwxr-xr-x 1 root root 12 Dec 17 13:55 NAME
$ cat /mnt/fd/NAME
hello world
就是这样。我希望这就是您要找的。有许多工具可以为您自动执行此过程,但是 dd
和铅笔和纸就可以完成。
完整的十六进制转储如下:

这是我的问题,您有什么建议吗?我怎样才能将 fat.img 更改为 .AME 到 NAME 以恢复我的文件?
how can i change fat.img to .AME to NAME to recovery my file?
简短的回答是dd
,下面是一个带有必要注意事项的示例。
添加到 Martin 的答案中,同时操纵字节以恢复软盘映像中的文件是一个相对直接的命题 dd
,计算文件分配的位置和内容 table( s) 需要恢复是挑战。通过使用 dd
恢复文件本身,了解需要注意的字节如下例所示。
创建要使用的软盘映像使您不必在实际映像上进行试验。只需复制您希望使用的图像,或在硬盘驱动器上的文件中创建一个新图像。您可以使用 mkfs.msdos
轻松做到这一点(根据需要调整文件系统类型),然后按如下方式将文件挂载到您的文件系统中,例如
$ mkfs.msdos -C /home/david/tmp/tt/floppy_144.img 1440
$ sudo mount /home/david/tmp/tt/floppy_144.img /mnt/fd
现在让我们添加 NAME
文件:
$ echo "hello world" > NAME
$ sudo cp -a NAME /mnt/fd
$ ls -l /mnt/fd
total 1
-rwxr-xr-x 1 root root 12 Dec 17 13:55 NAME
$ cat /mnt/fd/NAME
hello world
在从您的图像中删除文件之前,对内容进行十六进制转储,以便您可以准确地看到需要恢复的内容。 (这是您必须计算的内容,以便了解要用原始图像恢复到哪里以及恢复什么,您将需要查阅相关文件系统的参考资料)
$ hexdump -C floppy_144.img >flpwname.txt
现在从您的图像中删除该文件并再次保存显示更改的 hexdump。
$ sudo rm /mnt/fd/NAME
$ hexdump -C floppy_144.img >flpwoname.txt
现在您可以检查与 diff
的区别。你发现你必须恢复的不仅仅是被删除文件的名字,你将需要恢复文件分配 table 条目,以便恢复的文件可以再次位于文件系统中(两个副本的脂肪),例如
$ diff flpwname.txt flpwoname.txt

注意上面的文件分配 table(s) 在 0x204
和 0x1404
的条目在文件被删除时被清零。使用 dd
可以轻松将字节恢复为原始字节,但 请注意您的选项 。具体来说,你的 block size
(bs
)、output block size
(obs
)、count
和 seek
都必须在 bytes
中(指定通过将 c
) 附加到数字,您必须设置 notrunc
转换选项以防止在您进行更改后截断图像。最后,必须在 decimal
而不是 hexadecimal
.
此外,如果您使用 bash,您可以使用进程重定向来指定要替换的字节(例如 if=<(printf "\xf0\xff")
写入十六进制字节 f0
和 ff
),否则,您将不得不准备包含替换字符串的输入文件。恢复 FAT 和文件名第一个字符的 dd
命令相当简单(有关选项说明,请参阅 man 1 dd
)。
下面我们恢复FAT的第一个副本,然后是第二个,最后恢复文件名的第一个字符。 seek
(偏移量)值只是由 hexdump
提供的转换为十进制的值。 (您应该在进行更改之前卸载您的文件系统。您可以在安装软盘映像时进行更改,但在您重新安装之前它们不会反映出来)
$ sudo umount /mnt/fd
$ dd if=<(printf "\xf0\xff") of=floppy_144.img \
bs=1c obs=1c count=2c seek=516c conv=notrunc
$ dd if=<(printf "\xf0\xff") of=floppy_144.img \
bs=1c obs=1c count=2c seek=5124c conv=notrunc
$ dd if=<(printf "N") of=floppy_144.img \
bs=1c obs=1c count=1c seek=9728c conv=notrunc
现在您可以创建修复后的软盘映像的 hexdump 并将其与原始文件进行比较。如果一切顺利,那就没有区别了。
$ hexdump -C floppy_144.img >flprepair.txt
$ diff flpwname.txt flprepair.txt
最后,只需重新挂载您的文件系统并确认文件已恢复。
$ sudo mount /home/david/tmp/tt/floppy_144.img /mnt/fd
$ ls -l /mnt/fd
total 1
-rwxr-xr-x 1 root root 12 Dec 17 13:55 NAME
$ cat /mnt/fd/NAME
hello world
就是这样。我希望这就是您要找的。有许多工具可以为您自动执行此过程,但是 dd
和铅笔和纸就可以完成。
完整的十六进制转储如下:
