fat32-analyzer's Introduction

FAT32-analyzer

本工具用于分析FAT32文件系统，分析内容包括包括：
  • MBR(Master Boot Record) - 使用-m参数
  • VBR(Volumn Boot Record) - 使用-v参数 同时需要输入需跳过的扇区数 该项数据可以在-m指令中找到

-a选项可以同时分析MBR与VBR

同时，本工具也可以用于FAT32设备的文件恢复工作，可以恢复最近删除的文件，参数为-r.
请注意本工具的用法，本工具仅运行在Linux环境下：
    1. 将需要分析或者恢复文件的设备通过USB口连接到主机
    1. 除-s/-h参数选项外，使用其他选项运行时还需输入设备名称，设备名称请使用fdisk -l命令来查看。
    1. 参见下方[Usage]

请注意，恢复文件只能恢复文件内容，文件名无法完全恢复，且文件内容必须在Linux系统下查看。

关于FAT32文件系统的更多信息，请移步Wiki。

Usage:

python fat32_analyzer.py [options] [argument]

Options:

-h, -- help               get help                 

-s [sectors]              change the number of sectors that you want to read 

-m [device]               analyze the MBR                         

-v [device] [sectors]     analyze the VBR, MUST input the sectors to skip

-a [device]               analyze things above                    

-r [device]               recover file as possible

Example:

  • on Linux:
    • just type in the terminal python fat32_analyzer.py -r sdb.
    • then you can recover the files that recently deleted on sdb.
    • As for the device name, you can use the fdisk -lcommand to see.

Attention:

  • This tool can only run on Linux.
  • This tool can only undelete the files that are RECENTLY DELETED.You can find the completed content of the undeleted files on Linux,but the undeleted files'names might be a little different.
