【摘要】 目的在对IDE接口硬盘中的电子数据进行检验时保证其被写保护。方法利用单片机芯片、相关电路和固化程序拦截对硬盘的写指令。结果将一块IDE硬盘通过此接口连接到PC机实验表明,在对其进行写操作时已被写保护。结论利用单片机可以实现IDE硬盘的写保护。更多还原

【Abstract】 Objective to prevent the original electronic date in a IDE port hard disk from changing when check it. Methods Link the IDE port hard disk and the computer with Mcu chip and peripheral circuit,write infixed programme to hold up writing-order,thereby protect the content in hard disk. Results Link a IDE hard disk to the computer through this port ,when write file in it, a dialog box will pop to tell you this order can not be done. Conclusion For this case,it can be done by a IDE-USB port designed by MCU STC89C54 to protect the content of a IDE port.更多还原
