When reading a file or running a program, the system reads the disk repeatedly, and there is always an error message. Sometimes it takes a long time to read hard disk data, and the hard drive makes a lot of noise. In this case, the most likely reason is that there is a bad track on the hard drive. You can use the system's disk scanning tools, NDD and other disk tools to check and repair the hard disk. If this method does not solve the problem,
