Each code for current which is the main purpose of hard disk hard disk partition and obtain partition ID such as:


The following is a master to help write the code but get a little mistakes in my computer, and could not contact him so please cow elder brothers here help
Failed to get to my F plate is under which hard disk and partition is I get to the screenshot
