如何使用WinHex脚本自动修复FAT32文件系统DBR

        此脚本不是去复制备份的DBR,而是通过文件系统计算BPB参数,来达到修复文件系统的目的,下面是脚本:

 

Assign ParSize GetSize
Assign SecSize 512

Assign FAT1 CurrentPos
Move SecSize
EndIF

Find 0xF8FFFF0FFFFFFF Down
IfFound
Assign FAT2 CurrentPos
Move SecSize
EndIF

Goto 0x024
Write ((FAT2/SecSize)-(FAT1/SecSize))

Goto 0x00E
Write (FAT1/SecSize)

Goto ((FAT2-FAT1)+FAT2)
Find 0x2E20202020202020202020 Down
IfFound
Assign SEC1 CurrentPos
Move 26
Read CDX1 2
EndIF

Find 0x2E20202020202020202020 Down
IfFound
Assign SEC2 CurrentPos

Read CDX2 2
EndIF

Goto 0x00D
Write (((SEC1/SecSize)-(SEC2/SecSize))/((CDX1)-(CDX2)))
