硬盘FAT文件系统原理的详细分析 硬盘由很多盘片(platter)组成，每个盘片的每个面都有一个读写磁头。如果有N个盘片。 就有2N个面，对应2N个磁头(Heads)，从0、1、2开始编号。每个盘片被划分成若干个同心圆磁道(逻辑上的，是不可见的。)每个盘片的划分规则通常是一样的。这样每个盘片的半径均为固定值R的同心圆再逻辑上形成了一个以电机主轴为轴的柱面(Cylinders)，从外至里编号为0、1、2⋯ ⋯ 每个盘片上的每个磁道又被划分为几十个扇区(Sector)，通常的容量是512byte，并按照一定规则编号为1、2、3⋯ ⋯ 形成Cylinders×Heads×Sector个扇区。这三个参数即是硬盘的物理参数。我们下面的很多实践需要深刻理解这三个参数的意义。
