Windows automatically runs Check Disk when it detects a problem with the system. CHK files are invalid files, so instead of deleting files found to be invalid, Check Disk “chkdsk” put it in a folder named FOUND.OOO.

What is the cause of this behavior? These symptoms occur when there is damage to the selected Backup Source disk, in the file itself, or so-called “bad sectors” (physical damage) of the disk. The same applies to Source and Target disks during recovery. How do you fix corruption?

Windows provides a utility called chkdsk which can fix most disk space errors. The chkdsk utility must be run from a command prompt for it to work. In this How To article, we’ll learn what chkdsk does and how to use it to work around the problems above, as well as others not listed in the intro here.

So what exactly does chkdsk do? Good question. The main function of chkdsk is to scan data on disks (NTFS, FAT32) and check the integrity of the data and metadata, and fix the problem of incorrect data it sees. These errors may include incorrect entries in the master volume data (MFT), incorrect security descriptors associated with the data, or invalid paper time or data about a single file.

Chkdsk can scan for malware. Malfunctions come in two types: malfunctions, which occur when data is written incorrectly, and malfunctions that occur due to physical damage to the disk. Chkdsk tries to fix this problem by fixing the bad stuff and marking the bad stuff never to be used again.

How to make a hard disk corrupt? Another good question. Whenever Windows closes abnormally or crashes, it can cause corruption. At the same time, you can expect that you will face this kind of corruption. Running chkdsk as part of routine maintenance is good practice if you wish to do so.

As you can see, there are many permissions in the chkdsk tool that can provide some advanced functionality.

In general for this discussion we will look at the two most useful and most frequently used options. They:

The screenshot above shows the result of chkdsk with the /f option applied to the C: partition. As you can see, the command failed because the disk was being used by another process. It runs on the next reset if needed, type y to allow scanning. This happens when running chkdsk on boot into Windows.

Another note here is that the /r option of chkdsk appears in the same message as shown below:

What if we run chkdsk on partition C: with no options? Below is a display of one of the results.

When chkdsk is run with no options, chkdsk runs in read-only mode and reports the overall health of processes on the partition. This is a good scan to run on your disk partition as usual to clean your disk. If the analysis has found problems with the files, then run or schedule to run chkdsk /f and then try to fix the errors found.

So what’s the difference using the /r option in chkdsk? Chkdsk used with the /r option runs “Level 4:” scans partitions and looks for bad groups in user files. Once done, the utility will display how many files have been processed and the status of the scan.

After a Level 4 scan, the utility then runs a “Level 5” scan on the partition and looks for bad groups on the disk. When this analysis is complete, the utility shows how many white groups have been completed and the status of the scan.

After chkdsk has finished scanning, the utility shows the details of what it found and what status to do if it works. Below is a summary of the disk scan that found no errors.

Now that we’ve covered the basic use of the chkdsk utility, it’s time to learn how to use the utility on the Windows System OS disk. We have seen that chkdsk will not run on a booted Windows System C: partition / volume unless / until the computer is restarted. You may have noticed at this point that chkdsk works on individual partitions on the disk. A Windows System OS disk formatted as a GPT disk, like most modern Windows installations, may have multiple partitions on the disk. The fact is that disk corruption can occur in any disk partition. The error may be in more than one partition on one disk as well. Additionally, Windows System disks may have partitions on disks that are not driver-assigned which makes using the chkdsk utility for their work more difficult.

So what do you do with the problems mentioned above? Good question! Let’s see how to solve this problem.

To get started, let’s take a look at the correct installation of Windows 10 on a GPT formatted disk using Windows Disk Management.

As you can see in the screenshot above, this disk has four partitions. They are Recovery (450 MB), EFI (99 MB), Windows 10 PRO (237.08 GB), and OEM (861 MB). Note that only one partition has a drive letter, namely the Windows 10 partition with the letter (C:) given as you would expect. We don’t all share letters. To use the chkdsk utility to find and fix errors, the utility must be run on each disk partition, one at a time. It is important to provide temporary drives for partitions without a working script to perform a chkdsk scan on them.

It is possible to use the Windows Disk Management tool to assign a drive letter to this partition. To do this, place your mouse cursor on the partition where you want to put the letters and left click there. You will notice that the partition background takes the hash as shown below.

When selecting a partition, leave your mouse cursor on the selected partition, click the right mouse button, a new menu will appear that will allow you to send a letter to the given section. Select Change Driver and Route as shown below.

Disk Management will automatically select the next available file in this task as shown below. Click OK to issue the script.

The screenshots here and below show that the partition has been assigned the letter F:, which now allows you to run a chkdsk scan on the partition.

You can see that Disk Management cannot complete the driver task. When you select a distribution as listed above and right click, you can see a small box with the word Help. Another problem that occurs is that the options to change drivers and Paths are grayed out and therefore not selected. There could be many reasons for this. One of the most common reasons is that the partition type is not NTFS or FAT32. In this case, the only way to solve the problem is to delete the Volume and update it. This situation is usually caused by the disk itself
