Windows 10: How much is the result of CHKDSK trusworthy?

1. If Stages 1, 2, and 3 give no errors or fix all the errors detected, can we assume that files are OK.2. I assume that faulty sectors are removed by Stage 4 and 5? If some sectors used by files are faulty, how those files can be restored?3. What EAT stands for?4. I backed up the System Image and restored from that backup. Then the restored C partition was faulty as the original C partiton was faulty.Then I fixed the C partition by instlalling the disk on another computer although the drive letter was automatically changed from C. We can find the drive letter automatically assinged by

Retrieving Windows 10 chkdsk D: /r results

I performed the task and the results are "Event ID: 26226. Number of events: 0. Most of the suggestions that I have found for retrieving chkdsk results are for the OS drive C:. This is an external disk connected via USB 3.1_1.

 

chkdsk c: /F

It might be an error on the drive. We suggests that you follow the troubleshooting steps below:

• Run Disk Cleanup utility to clear your junk files.
• Open an elevated CMD type sfc /scannow and hit Enter to run the System File Checker.
  
• Once the scan is completed, restart your computer. Remember to exit ChkDsk
  during boot.
• Next, again open CMD as admin type
  Dism /Online /Cleanup-Image /RestoreHealth and hit Enter to repair the Windows image.
• Now see if ChkDsk able to complete the scan.

Note: Before doing the steps, make sure you save a back up of your files.

Let us know how it goes.

 

chkdsk c: /F

We appreciate the response. I'm referring to Check Disk (chkdsk) utility tool. If you haven't tried yet, we suggest that you run a chkdsk by:

• Press Windows Key + X button to bring up the power user menu.
• In the power user menu, select the Command Prompt (Admin) option.Click Yes when you are presented with a UAC window requesting permission to launch the Command Prompt as Administrator.
• In the new Command Prompt window, type chkdsk E: /f /r /x. Here you should replace E with your drive letter.

This option will run chkdsk to check and repair disk errors in Windows 10. The “/f” parameter tells CHKDSK to fix any errors it finds; “/r” tells it to locate the bad sectors on the drive and recover readable information; “/x” forces the drive to dismount
before the process starts.

Keep us updated with the result.
