IDE接口硬盘读写技术

分析了IDE接口硬盘控制寄存器模型；论述了IDE接口硬盘的读写几项技术；给出了设计硬盘克隆软件的思想和方法，方法针对硬盘物理扇区进行读写，与硬盘上安装的具体操作系统的类型无关，并与硬盘驱动器的物理结构无关。结合C语言与汇编语言，经实际应用验证，方法简便，具有较强的实用性。

关 键 词 IDE接口; 硬盘控制寄存器; LBA寻址; ATA标准

Abstract This paper analyse the model of controller registers for IDE interface hard disk drive, summarized some key technic about read-write hard disk drive and a design about clone hard disk. We can directly read-write the sector ,and it has no concern with operaTIng system and the structure of hard disk drive. Combine with C and Assemble language, We give an realy applicaTIon . the method is easy and useful.

Key words IDE interface; hard disk control register; LBA seek; ATA standard
