The chkdsk C: command runs CHKDSK on your C drive. For most people, the C drive is the main drive. With the same command, you can specify other disks you want to check by replacing chkdsk C: with chkdsk D: or any other letter corresponding to a specific drive.

Checks the file system and file system metadata of a volume for logical and physical errors. If used without parameters, chkdsk displays only the status of the volume and does not fix any errors. If used with the /f, /r, /x, or /b parameters, it fixes errors on the volume.
Membership in the local Administrators group, or equivalent, is the minimum required to run chkdsk. To open a command prompt window as an administrator, right-click Command prompt in the Start menu, and then click Run as administrator.
Interrupting chkdsk is not recommended. However, canceling or interrupting chkdsk should not leave the volume any more corrupt than it was before chkdsk was run. Running chkdsk again checks and should repair any remaining corruption on the volume.
If you choose to check the drive the next time you restart the computer, chkdsk checks the drive and corrects errors automatically when you restart the computer. If the drive partition is a boot partition, chkdsk automatically restarts the computer after it checks the drive.
You can also use the chkntfs /c command to schedule the volume to be checked the next time the computer is restarted. Use the fsutil dirty set command to set the volume's dirty bit (indicating corruption), so that Windows runs chkdsk when the computer is restarted.
You should use chkdsk occasionally on FAT and NTFS file systems to check for disk errors. Chkdsk examines disk space and disk use and provides a status report specific to each file system. The status report shows errors found in the file system. If you run chkdsk without the /f parameter on an active partition, it might report spurious errors because it cannot lock the drive.
Because repairs on FAT file systems usually change a disk's file allocation table and sometimes cause a loss of data, chkdsk might display a confirmation message similar to the following:
If you press Y, Windows saves each lost chain in the root directory as a file with a name in the format File.chk. When chkdsk finishes, you can check these files to see if they contain any data you need.
If you specify the /f parameter, chkdsk displays an error message if there are open files on the disk. If you do not specify the /f parameter and open files exist, chkdsk might report lost allocation units on the disk. This could happen if open files have not yet been recorded in the file allocation table. If chkdsk reports the loss of a large number of allocation units, consider repairing the disk.
Because the Shadow Copies for Shared Folders source volume cannot be locked while Shadow Copies for Shared Folders is enabled, running chkdsk against the source volume might report false errors or cause chkdsk to unexpectedly quit. You can, however, check shadow copies for errors by running chkdsk in Read-only mode (without parameters) to check the Shadow Copies for Shared Folders storage volume.
On servers that are infrequently restarted, you may want to use the chkntfs or the fsutil dirty query commands to determine whether the volume's dirty bit is already set before running chkdsk.
If it encounters errors, chkdsk pauses and displays messages. Chkdsk finishes by displaying a report that lists the status of the disk. You cannot open any files on the specified drive until chkdsk finishes.
The command is available in MS-DOS versions 1 and later.[7]CHKDSK is implemented as an external command. MS-DOS versions 2.x - 4.x use chkdsk.com as the executable file. MS-DOS versions 5.x and later use chkdsk.exe as the executable file.[8]
These commands will automatically run on the active drive shown next to your cursor. To run CHKDSK on a different drive, type chkdsk [drive letter]: /f, replacing [drive letter] with the letter of the drive you want to scan. For example, to repair the D drive, enter chkdsk D: /f.
Chkdsk /r is not meant to be a data recovery utility, and it sometimes doesn't recover corrupted files properly. The safest method for data recovery is to use a previously created backup, or to ask an expert before executing chkdsk /r.
This error message means that CHKDSK has found something that needs fixing. First, make sure you understand what chkdsk /r does, and bear in mind that there is some risk of losing important files when running a repair scan. Then, run chkdsk /r using Command Prompt.
Other less commonly used chkdsk command switches exist too, like /B to re-evaluate bad clusters on the volume, /forceofflinefix which runs an online scan (a scan while the volume is active) but then forces the repair to run offline (once the volume has been dismounted), /offlinescanandfix which runs an offline chkdsk scan and then fixes any problems that were found, and others that you can read more about through the /? switch.
I am trying to use the chkdsk.exe system tool found in C:\Windows\System32\chkdsk.exe from a C# Winforms app. I want to use the System.Diagnostics.Process Class. I am using the ProcessStartInfo to set the file name to the tool and then using the args property to set my arguments.
So I have tried using System.Diagnostics.Process with ProcessStartInfo. But when the error occurs when the user does not have the permissions the chkdsk window immediately closes. So I see the window in the task bar for a moment and then it closes without saying anything. I have tried both UseShellExecute=true and false. Also, I have tried redirecting the output stream but in a Windows app, I would have to display the output stream directly if it fails rather than a CMD window showing the error or the CHKDSK info.
I want the CHKDSK text to be displayed in a CMD window I believe. So if the user does not have permissions the window should tell the user they do not have the permissions like it would using a CMD window and typing "call chkdsk /r /f C:" I do not want to use start an instance of CMD and pass chkdsk as a parameter. I want to use just the CHKDSK.exe tool
XenDesktop 5 SP1, using Prov services and vdisks.. we were having issues with a web application, and their support tech asked me to put the VM in Private mode to try a few things. I noticed upon booting up the vdisk now BSOD's with BAD_SYSTEM_CONFIG_INFO I am trying to figure out how to run a chkdsk on the vdisk.. just can't wrap my mind on a way to mount it some how?
Running CHKDSK will require that the volume be dismounted if you are fixing errors or recovering bad sectors. My guess is that's what Windows wants to do on that volume and you should run it sooner rather than later. You will definitely want to backup data first and then run the chkdsk on a reboot.
I was just curious if it is safe to run chkdsk /r on a drive that holds an active SQL db? This is a SQL Server running on a VM. I was told to run the chkdsk command by an Acronis support technician, because their backup software is telling me that there are errors on the drive. Yet all the other VM backups are working just fine and they are all running on the same host. The SQL server itself runs perfectly without any issues and is a production server.

First, when it comes to disk fixes, I'd not do anything while the server is actually doing it's regular business. Then again, you can't run chkdsk on a boot drive while the system is booted from it, but it's unclear where your data is. Are you checking a VHD/VHDX with this and is it the one with the database data on it?
To answer your question, you probably know chkdsk reads each sector of a disk and /r attempts to recover data and move it to a new block if damaged. If anything, I'd run it without the /r command first. It may be helpful to see if it turns up a problem at all without actually trying to recover the sector. If it does turn up an issue, it's really virtual sectors you're dealing with.
So the process works for non cloud backups for the same databases/server and the vendor is recommending you run a chkdsk/r for the same backups failing to cloud bu's? Did they give a reason for this?
In order to run checkdisk to repair the hard drive, you should type the following: chkdsk C: /r and press Enter. If Vista is installed on a drive besides the C: drive, you should replace C: with the appropriate drive letter.
