MBR解析

先推广一下QQ群：61618925。欢迎各位爱好编程的朋友加入。

一、程序界面

二、关键部分代码：

1.数据结构定义

#define MBRSIZE 512
#define BOOTRECORDSIZE 440
#define DISKSIGNEDSIZE 4
#define RESERVESIZE 2
#define DPTNUMBER 4
#define DPTSIZE 16
#define ENDSIGNSIZE 2


typedef struct tagBOOTRECORD 
{
    UCHAR szBootRecord[BOOTRECORDSIZE];
}BOOTRECORD, *PBOOTRECORD;


typedef struct tagDPT
{
    UCHAR szBootSign;            //引导标志，0x80表示活动分区，0x00表示非活动分区
    UCHAR szStartHeadNumber;    //起始磁头号
    UCHAR szStartSectorNumber;    //起始扇区号，低6位
    UCHAR szStartCylinderNumber;//起始柱面号，起始扇区号的高2位+起始柱面号
    UCHAR szPartitionType;        //分区类型，0x00表示该分区未使用（即未指定）,0x06表示FAT16基本分区，0x0B表示FAT32基本分区，0x05表示拓展分区,0x07表示NTFS分区，0x0F表示（LBA模式）拓展分区（0x83为Linux分区等）。
    UCHAR szEndHeadNumber;        //结束磁头号
    UCHAR szEndSectorNumber;    //结束扇区号，低6位
    UCHAR szEndCylinderNumber;    //结束柱面号，结束扇区号的高2位+结束柱面号
    ULONG ulSectorsPreceding;    //本分区之前使用的扇区数
    ULONG ulSectorsInPartition;    //分区的总扇区数
}DPT, *PDPT;

typedef struct tagMBR
{
    BOOTRECORD BootRecord;//引导程序
    UCHAR ulSigned[DISKSIGNEDSIZE];        //Windows磁盘签名
    UCHAR szReserve[RESERVESIZE];        //保留位
    DPT Dpt[DPTNUMBER];            //分区表
    UCHAR szEndSign[ENDSIGNSIZE];        //结束标志
}MBR, *PMBR;
