Windows 10 can detect and attempt to repair errors on your hard drive. But sometimes it is also necessary to force this operation, and it can be done with Check Disk or Chkdsk of its name in the Command Prompt. Here is a guide to using the Check Disk tool that comes with all versions of Windows. 

 

Check Disk utility can rescue your hard drive or SSD and it is advised to use it whenever your system behaves strangely. Sometimes even if apparently the problem does not come from your Hard disk. The program chkdsk can fully scan your hard drive for bad sectors. Two cases then arise: either chkdsk can réparer the failing sector, or it cannot.



In this second case, it marks the sector in question so that the system no longer tries to use it. Beforehand, you can perform a faster analysis that aims to find logical errors in the file system. Such an analysis can solve many problems in itself. It is recommended that you run the utility regularly to prevent these errors from damaging your data.

If the errors multiply, it means that your disk or SSD is reaching the end of its life, it must then be changed. If you're going for a hard drive, check out this list of the most reliable brands!
