Windows 10: Does chkdsk x: /r exclude faulty sectors in partition x?

When I excute chkdsk x: /r where x is a partition letter on one of my disks, no errors are detected in Stages 1, 2, and 3. However, while looking for bad clusters in Stage 4, "Progress m of n" is suspended for some time, does this mean that a bad cluster is detected? The same problem occurs at the same clusters when the scan by chkdsk is repeated. Hence it does not seem that the problem is fixed.Stage 5 procees without any interrupton,At the end , the following message is shown: "Windows has scanned the file system and found no problems. No further action is required." Does this mean, the

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.

 

How do I run CHKDSK on EFI System Partition?

On Windows, I used DISKPART to assign the EFI System partition a letter. Fired up DISKPART, and typed LIST DISK to find the disk, followed by SELECT DISK <N> (where is the drive number). Followed the same steps to find the proper partition (i.e. LIST PARTITION followed by SELECT PARTITION <N>), and then simply typed ASSIGN LETTER = X to have Windows mount the partition to letter X.

Then opened CMD with administrative access. Ran CHKDSK X: /f /r

Then, I tried installing Ubuntu once again, and it installed successfully!
