详解MBR分区结构以及GPT分区结构

详解MBR分区结构以及GPT分区结构一、MBR分区结构MBR磁盘分区是一种使用最为广泛的分区结构,它也被称为DOS 分区结构,但它并不仅仅应用于Windows系统平台,也应用于Linux,基于X86的UNIX等系统平台。
它位于磁盘的0号扇区(一扇区等于512字节),是一个重要的扇区(简称MBR扇区)。
MBR扇区由以下四部分组成:引导代码:引导代码占MBR分区的前440字节,负责整个系统启动。
如果引导代码被破坏,系统将无法启动。
Windows磁盘签名:占引导代码后面的4字节,是Windows初始化磁盘写入的磁盘标签,如果此标签被破坏,则系统会提示“初始化磁盘”。
MBR分区表:占Windows磁盘标签后面的64个字节,是整个硬盘的分区表。
MBR结束标志:占MBR扇区最后2个字节,一直为“55 AA”。
注意:分析磁盘使用的工具是Winhex,如果读者需要请自行下载。
下面详细分析分区表结构磁盘在使用前都要进行分区,也就是将硬盘划分为一个个逻辑的区域。
每一个分区都有一个确定的起始结束位置。
MBR磁盘的分区形式一般有3种,既主分区,扩展分区和非DOS分区。
主分区既主DOS 分区,扩展分区既扩展的DOS分区(扩展分区可以分逻辑分区),非DOS分区对于主分区的操作系统来说是一块被划分出去的区域,只能非DOS分区中操作系统可以管理。
如下:是MBR分区表MBR一共占用64个字节,其中每16个字节为一个分区表项。
也就是在MBR扇区中只能记录4个分区信息,可以是4个主分区,或者是3个主分区1个扩展分区。
每个分区项中对应的字节解释如下表:扩展分区的结构分析由于MBR仅仅为分区表保留了64字节的存储空间,而每个分区则占用16字节的空间,也就是只能分4个分区,而4个分区在实际情况下往往是不够用的。
因此就有了扩展分区,扩展分区中的每个逻辑分区的分区信息都存在一个类似MBR的扩展引导记录(简称EBR)中,扩展引导记录包括分区表和结束标志“55 AA”,没有引导代码部分。

硬盘MBR和GPT分区详解

硬盘MBR和GPT分区详解目前磁盘分区有两种形式:GPT分区和MBR分区。
MBR相比而言比较常见,大多数磁盘都是采用这种分区形式。
MBR分区和GPT分区的区别在于:MBR最多只支持4个主分区,GPT能够支持128个主分区。
然而GPT分区形式在重装系统需要主板的EFI支持,所以导致出现上面的这种情况。
因此解决的办法就是将分区形式转换为MBR分区形式。
但是在转换之前必须要做好数据备份,将磁盘里重要的东西全部拷出来,因为只有整个磁盘全部为空时,才能够进行转换。
传统的分区方案(称为MBR分区方案)是将分区信息保存到磁盘的第一个扇区(MBR 扇区)中的64个字节中,每个分区项占用16个字节,这16个字节中存有活动状态标志、文件系统标识、起止柱面号、磁头号、扇区号、隐含扇区数目(4个字节)、分区总扇区数目(4个字节)等内容。
由于MBR扇区只有64个字节用于分区表,所以只能记录4个分区的信息。
这就是硬盘主分区数目不能超过4个的原因。
后来为了支持更多的分区,引入了扩展分区及逻辑分区的概念。
但每个分区项仍用16个字节存储。
GPT磁盘是指使用GUID分区表的磁盘,是源自EFI标准的一种较新的磁盘分区表结构的标准。
与普遍使用的主引导记录(MBR)分区方案相比,GPT提供了更加灵活的磁盘分区机制。
MBR的全称是Master Boot Record(主引导记录),MBR早在1983年IBM PC DOS 2.0中就已经提出。
之所以叫“主引导记录”,是因为它是存在于驱动器开始部分的一个特殊的启动扇区。
这个扇区包含了已安装的操作系统的启动加载器和驱动器的逻辑分区信息。
主引导扇区是硬盘的第一扇区。
它由三个部分组成,主引导记录MBR、硬盘分区表DPT和硬盘有效标志。
在总共512字节的主引导扇区里MBR占446个字节,偏移地址0000H--0088H),它负责从活动分区中装载,并运行系统引导程序;第二部分是Partition table区(DPT分区表),占64个字节;第三部分是Magic number,占2个字节。
MBR分区表

MBR分区表构成MBR分区表以80为起始,以55AA为结束,共64个字节,分为4个分区表,一个可启动分区和三个不可启动分区。
其结构如下:分区表一:第1个字节80(HEX) *可启动分区第2~4字节01/01/00(HEX)*开始磁头/开始扇区/开始柱面换算一下,二进制表示就是。
0000 0001/00000001/0000 0000(BIN)*开始磁头/开始扇区/开始柱面以下将使用16进制表示,不再换算成二进制!第五个字节0C *分区类型FAT32 NTFS为07,可自己变更第6~8字节FE/FF/FF *结束磁头/结束扇区/结束柱面第9~12字节00 00 00 3F *分区前的隐藏扇区63个隐藏扇区,此设计使0磁道使用0扇区,而1到62扇区不使用,减少读取,以此保护分区表,个人认为是个很不错的设计,不过很少有人知道这个。
第13~16字节5B 24 40 01 *分区大小20980827个扇区当然好要算上分区表的63个扇区一共20980889个扇区合10GB 公式为20980889*512/(1024^3)=10GB------------------------------------------------------我是一条分割线-----------------------------------------------分区表二:第17个字节00:不可启动分区第18~20字节开始磁头/开始扇区/开始柱面第21字节0F *分区类型为扩展分区第22~24字节结束磁头/结束扇区/结束柱面第25~28字节分区前的隐藏扇区第29~32字节分区大小分区表三,分区表四,以此类推,不再解释。
至于分区表的修改WinHex(DISKEDIT DOS下)是个不错的软件,了解了这些,就可以自己重建分区表了。
另:MBR是主分区表,误操作使MBR损坏时,DBR或者DBR备份应该没损坏,我们可以通过搜索55AA来获得DBR信息(往前找就行了),来寻找DBR从而了解更多信息(主要是分区大小和开始结束的扇区,磁头,柱头),来帮助我们重建分区表。
