Error Explanation

"Windows has detected file system corruption on local disk (C:). You must check the disk for errors before it can be restored."

It's a Windows 10/8/7 System Restore error that suggests either a file system corruption on the selected hard disk or a corruption of Windows system files. By facing this error, you cannot perform any system restore point until the exact error was thoroughly resolved.

You may receive another two similar error messages: "The local disk (C:) has errors" and "The disk OS (C:) has errors." 

Whenever you're faced with the above error messages, you can't run the System Restore to the end. Check this page's solutions because you really need the help.

Move on to the following advanced solutions if you're out of luck to overcome the trouble after the initial attempt.

Solution Two. Run System File Checker Scan (SFC) to fix corrupted system files

Follow the step-by-step instruction provided here to use the System System File Checker tool to scan system files and repair missing or corrupted system files. Those system files in question are prominent reasons for the Windows being unable to run System Restore properly.

1. Right-click the Start button and select "Command Prompt (Admin)".
2. Type "sfc /scannow" into the Command Prompt window and press Enter to run a full system scan.

Solution Three. Run CHKDSK /F to check and repair disk errors

Like we previously mentioned, the "Windows has detected file system corruption" is largely attributed to two factors. We provided you with solutions to deal with the system files issue in the second solution, now it's time to focus on the other suspicious factor which is related to hard disk errors.

1. Click Start, and then Run.
2. In Open, type cmd, and then press ENTER.
3. To run chkdsk on C drive, type  chkdsk c: /f, and then press Enter.

Tip:

1. If the Chkdsk gets stuck unfortunately at a certain percentage number, click this post to get over with it.
2. While performing chkdsk on the hard drive, if any bad sectors are found on the drive, the command will execute the operation to repair the sector. So, all data on that sector will be lost. If it's important data you don't want to lose, after all the repair was done, download EaseUS free file recovery software to recover files deleted by Chkdsk. It's easy and quick.

  • Select the hard drive after Chkdsk and click Scan.
  • Scan all over the hard drive to find lost data.
  • Preview and select files you wish to restore and click Recover.

Solution Four. Perform disk defragment by choosing a proper method

This is a final step to check if the hard drive errors were solved and optimize your hard drive as well. You can run disk fragment from the command prompt or using a third-party free partition manager.
