System File Checker (SFC) is a kind of Windows built-in utility that enables users to scan and restore corrupted system files./p>
There are two simple ways to run a System File Checker scan. The first one is to run sfc /scannow in an elevated Command Prompt. The second choice is to run an SFC scan inside the Windows Powershell (Admin).

Solution 4. Check If There Are Any Physical Bad Sectors on Your Hard Disk
If all the above methods failed to find and fix the error, then perhaps you need to consider making a disk surface test to check if there are any physical bad sectors in your hard drive.
Here, it is highly recommended that you try to use a free third-party tool MiniTool Partition Wizard. This marvelous software breaks some limitations and offers flexible solutions to optimize your hard drive, such as rebuild MBR, wipe disk, disk surface test and so forth.

Step 3. Inside the disk surface test window, click on the Start Now button.
Step 4. After that, this program will automatically test the hard disk and show the test result. If there is a bad sector on this disk, the disk block will be marked with a red color. On the contrary, the disk block without bad sectors will be marked as green color.
If there is a large size of the red area, it is an indicator that you should consider using a new trusted hard disk to replace it.
As we mentioned above, some users want to delete all partitions on a hard disk (except the system partition) to solve this problem.
