| 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. |
