Is your disk HDD?
You can try defrag for this.
If you can't find out what corrupted your file, you risk losing a very important file or project in the future.
Type and run chkdsk with CMD. (Run as administrator)
This will find and repair any problems on your disk.
To run Check Disk in read-only mode, type chkdsk at the command prompt and press <Enter>.
If you only want to repair errors without performing a scan to detect bad sectors on the disk, type chkdsk volume:/f at the command prompt and press <Enter>.
To repair errors, bad sectors, and readable information, type chkdsk volume:/r at the command prompt and press <Enter>.
Maybe windows may have fixed that part in the disk scan.
When you say fix, if there is a physical problem on your disk, it marks the damaged part and ignores it.
