In this How To article, we will learn what chkdsk does and how to use it to overcome the issues above, as well as others not listed in the intro here.So what does chkdsk do exactly? Good question. The chkdsk utility must be run from an administrator command prompt to perform its work. How do you fix such corruption?Windows provides a utility tool known as chkdsk that can correct most errors on a storage disk.

Chkdsk attempts to fix these problems by repairing soft bad sectors and marking hard bad sectors so they wonвЂ™t be used again.How does a hard disk become corrupted? Another good question. Bad sectors come in two forms: soft bad sectors, that occur when data is written badly, and hard bad sectors that occur because of physical damage to the disk. These errors might include corrupt entries in a volumeвЂ™s master file table (MFT), bad security descriptors associated with files, or misaligned time stamp or file size information about individual files.Chkdsk can also scan for bad sectors.

If chkdsk cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer.Displays the name of each file in every directory as the disk is checked.Locates bad sectors and recovers readable information. You can use the ? and * wildcard characters to specify multiple files.Fixes errors on the disk. Specifies the location and name of a file or set of files that you want chkdsk to check for fragmentation. Running chkdsk as part of a normal maintenance routine is good practice if you wish to do so.Enough of the technical stuff, letвЂ™s see what we can do with the chkdsk utility.First, letвЂ™s outline the tools various command line switches and their uses.Chkdsk ]] ] Specifies the drive letter (followed by a colon), mount point, or volume name.Use with file allocation table (FAT) and FAT32 only. Over time, you can expect that you will experience such corruption.

If you omit the size parameter, /l displays the current size.NTFS only: Clears the list of bad clusters on the volume and rescans all allocated and free clusters for errors. Changes the log file size to the size you type. Does not check cycles within the folder structure, which reduces the amount of time required to run chkdsk.Use with NTFS only. Performs a less vigorous check of index entries, which reduces the amount of time required to run chkdsk.Use with NTFS only. /x also includes the functionality of /f.Use with NTFS only. All open handles to the drive are invalidated.

Once this scan completes, the utility displays how many free clusters were processed and the status of the scan.Below are screenshots of each Stage of the chkdsk /r scan once completed.After chkdsk finishes with a scan, the utility displays a summary of what was found and a status of what if any actions were performed. Once that completes, the utility will display how many files were processed and the status of that scan.After the Stage 4 scan, the utility then runs a вЂњStage 5вЂќ scan of the partition and looks for bad free clusters on the disk. If the scan check results in finding an issue with the filesystem, then running or scheduling a run of chkdsk /f will then attempt to fix the found error(s).So what difference does using the /r option make in chkdsk? Chkdsk used with the /r option runs a вЂњStage 4:вЂќ scan of the partition and looks for bad clusters in user file data.

A Windows System OS disk formatted as a GPT disk, as most modern Windows installs are, may have several partitions on a disk. You may have noticed at this point that chkdsk works on individual partitions on a disk. We have already discovered that chkdsk will not run on a booted Windows System C: partition/volume unless/until a restart of the computer occurs.

They are a Recovery (450 MB), EFI (99 MB), Windows 10 PRO (237.08 GB), and OEM (861 MB). Additionally, Windows System disks will have partitions on a disk that are not assigned drive letters which makes using the chkdsk utility on them a more challenging task.So how do you deal with the issues raised above? Good question! LetвЂ™s have a look at how to deal with these issues.To begin, letвЂ™s have a look at a typical Windows 10 install on a GPT formatted disk by using Windows Disk Management.As you can see in the screenshot above, this disk has four partitions. Corruption may exist on more than one partition on a single disk as well.

There can be a number of reasons for this. Another issue that occurs is that the option to Change drive letters and Paths is greyed and is therefore non-selectable. When you select a partition as outlined above and right button mouse click it you may simply see a small box with the word Help displayed. Click on OK to assign the letter.The screenshot here and below shows the partition has been assigned the letter F:, which now enables you to run a chkdsk scan on that partition.You may find that Disk Management is unable to complete the assignment of a drive letter task.

For a How To on command prompt usage click HERE. The utility we will use to do this is the diskpart utility and must be run from an administrator command prompt. Removing the Read Only attribute will solve that issueIn other circumstances it will be necessary to use another Windows utility to make the letter assignment to the selected partition. This situation is usually the result of the disk itself being previously used in a MAC.Another issue that may be in play is that the partition has a Read Only attribute set. In this case, the only way to resolve the issue is to Delete the Volume and reformat it.
