This program does a low level read of storage media, harddisks, floppys, usb sticks, memory cards, CD/DVD etc. There is as of today no help for this program. Move the mouse over the tool buttons to get an explanation of their functions.

1． 本实验是模拟操作系统的磁盘寻道方式，运用磁盘访问顺序的不同来设计磁盘的调度算法。 2． 实现的磁盘调度算法有FCFS，SSTF，SCAN，CSCAN和 NStepSCAN算法。 3． 设定开始磁道号寻道范围，依据起始扫描磁道号和最大磁道号数，随机产生要进行寻道的磁道号序列。 4． 选择磁盘调度算法，显示该算法的磁道访问顺序，计算出移动的磁道总数和平均寻道总数。 -1. This experiment is a simulation of the operating syst
