DT Tune's health tests are all red, but the status shows normal. Is my computer hard disk broken or not? Is it serious?

HDtune is changed to the latest version and tested again. The so-called hard disk test results are for reference only. Just because he says it's broken doesn't necessarily mean your hard drive is broken. Test it with another software. In addition, test with the latest software, not the old version. You can also use the software that comes with windows to measure, run-cmd-and enter "ScanDisk X:" to scan and repair the hard disk (X is the specific hard disk letter). If there is a problem, win will ask you whether to fix it. Just click "Yes".
