How to fix HDD disk error found by Defender?

BenjaminMiller 1.Before attempting repairs, make sure to back up any critical data to an external drive or cloud storage. This ensures that you have a copy of your important files in case the drive fails.
2. Run CHKDSK (Check Disk)
Windows includes a built-in tool called Check Disk (CHKDSK) that scans and repairs file system errors and bad sectors on the disk.
3.Open Command Prompt as an administrator:
Press the Windows key, type cmd, right-click on Command Prompt, and select Run as Administrator.
In the Command Prompt window, type the following command and press Enter:
chkdsk C: /f /r
4.Replace C: with the letter of the drive you want to check if it's different.
You may be prompted to schedule the disk check upon the next restart if the drive is in use. Respond with Y and restart your computer.
