What do you think the data of HD Tune hard disk detection tool represents?

Maximum: Maximum transfer rate Average: Average transfer rate Access: Burst of access time: Random transfer rate CPU usage: The option at the bottom of CPU usage starts a quick scan. Check the fast scan, and the green box of the normal scan represents the normal state 1. Check the service life of the hard disk. There is a green progress bar at the top left of the window, and the length of the progress bar represents the service life of the hard disk. If the progress bar fills the whole column, it means that your hard disk has a good service life. If the progress bar has moved to the left for a certain distance, the service life is decreasing; The farther to the left, the shorter the service life. 2. Check the indicator light of the hard disk. Drive health will automatically detect the health status of the current hard disk and display it in the list in the main window. Here are items such as the original reading error rate and rotation time, and the most important thing for us is the values displayed under the "Status" column. Below, the author briefly introduces the meaning of each value: OK: in good condition; Property changed: A property has been changed; Danger Pre T.E.C warning: Warning: If the value is OK, that is, if "AttributeName" is displayed as "√", it means that everything is normal and there is no need to worry; If the value is "dangerous change" or "Pre T.E.C warning", namely "AttributeName" is displayed as "!" You need to be careful in this case. But if it says "unlock!" This means that your hard disk may not support or activate this feature. 3. Save the hard disk test results. Select the "Save Report → Text File" item under the "Drive" menu to save the current test results to a text file. In addition, in the "Common Hard Disk Settings" window, you can set the monitoring of possible error levels of hard disks and the detection frequency. 3. Viewing Hard Disk Information Activate the "Display Hard Disk Information" item under the "View" menu, and we can view the relevant information of the hard disk on the right side of the window. This function is similar to hardware detection tools. From here, you can learn the hard disk manufacturer, model, product serial number, Fireware version, block size, total capacity, current sector number, total sector number, track, head and other information. More importantly, you can also check the super DMAT operation mode of the hard disk to see if the hard disk supports temperature control settings. If temperature control is supported, the current hard disk temperature will be displayed in the drive temperature item. Drive health occupies little system resources, so we can add it to the "startup" group to run as the background service of X-system, so that we can get timely warning when there is a problem with the hard disk and win valuable time for the preservation of important data. Red squares represent defects.
