用BUSBOND抓出来的东西好象用处不大，我抓了很多种U盘，它好象只能得到WINDOWS上层的数据，对于底层HOST芯片对数据的处理就不知道了，最好能用USB分析仪来抓，但分析仪太贵了，最少都要几万元，便宜的又不好用。

hi,lxhpt
可以详细讲讲你说的这几个部分所包含的内容么
你的那个文档我很早就看过了，不过其中并没有MBR的内容
还有你提到的Reserved region 存储的是什么内容
谢谢

BOOTSECTOR简介
Boot Sector 也就是硬盘的第一个扇区, 它由 MBR (Master Boot Record), DPT (Disk Partition
Table) 和 Boot Record ID  三部分组成。
MBR 又称作主引导记录占用 Boot Sector 的前 446 个字节 ( 0 to 0x1BD ), 存放系统主引导程序
(它负责从活动分区中装载并运行系统引导程序).
   DPT 即主分区表占用 64 个字节 (0x1BE to 0x1FD)， 记录了磁盘的基本分区信息，主分区
表分为四个分区项,，每项 16 字节，分别记录了每个主分区的信息(因此最多可以有四个主分区).
Boot Record ID 即引导区标记占用两个字节 (0x1FE and 0x1FF), 对于合法引导区，它等于 0xAA55
，这是判别引导区是否合法的标志。

MBR 又称作主引导记录占用 Boot Sector 的前 446 个字节 ( 0 to 0x1BD ), 存放系统主引导程序

请问，这446字节的主引导程序对任何磁盘都一样吗？ fat32的spec中并没有提及这446字节的具体内容。如果不一样，我应该怎么得到？

谁能说说U盘物理结构是怎么组织的吗？

跟硬盘是一样的！
MBR+PBR+FAT1+FAT2+ROOT+DATA

给我一份资料 tmeijun@126.com

能不能给我发点资料？
多谢了！

我也要一份谢谢！tomlee@shhic.com

给我也来一份，谢谢

MBR定义如下：
typedef struct {
uchar bootcode[0x1be]; //启动代码length=446.
PartitionTable PT[4]; //分区表length=4*16.
uint EndingFlag; //结束标识:0xAA55.
}MBR;
