How to Solve Checking File System on C Error in Windows
Checking File System on C message is a warning when Windows detects an issue with the file system on your C drive (typically the primary drive where Windows is installed). This message indicates that there may be corrupted or damaged files, bad sectors, or other issues that need attention to prevent potential data loss or system instability.
What is a Check File System on C Message?
The Check File System on C message is a prompt from Windows that suggests running a disk check utility, such as CHKDSK (Check Disk), to scan and repair any problems with the file system on the C drive. This message can appear during startup, Shutdown, or when attempting to access specific files or folders.
It serves as a precautionary measure to ensure the integrity of your data and prevent potential system crashes or performance issues.
Causes for Check File System on C
Several potential causes can trigger the “Check File System on C” message:
Corrupted File System
A corrupted file system can result from various factors, such as power outages, software conflicts, malware infections, or hardware failures. Corrupted files or system files can lead to inconsistencies in the file system, prompting Windows to recommend a disk check.
Bad Sectors Hard drives
A disk sector hard drive can develop bad sectors over time, which are areas on the Disk that cannot be read or written reliably. Bad sectors can cause data corruption and file system issues, leading to the Check File System on C message.
Incorrect Shutdown
If your computer is not shut down properly (e.g., due to a power outage or forced restart), it can leave the file system in an inconsistent state, triggering the need for a disk check.

Check File System Errors
The primary solution to address the “Check File System on C” message is to run the CHKDSK (Check Disk) utility. This tool scans the file system for errors and attempts to repair any issues.
Here’s how to run CHKDSK:
Open the Command Prompt as an administrator.
Type chkdsk C:/f /r and press Enter. ( Replace C with the appropriate drive letter if your Windows installation is on a different drive.
The /f parameter instructs CHKDSK to fix any errors it finds, and /r locates bad sectors and attempts to recover readable information.
CHKDSK will inform you if a disk check needs to be scheduled for the next restart. If prompted, select “Yes” to schedule the disk check.
Restart your computer, and CHKDSK will run automatically during the boot process, scanning and attempting to repair any issues found on the C drive.

Diable Autodisk Check Manually
If you don’t want Windows to automatically check the file system every time you start your computer, you can turn off the Autodisk Check feature manually. However, turning off this feature may prevent Windows from detecting and fixing potential issues with your file system.
To disable Autodisk Check, follow these steps:
- Start Button > Type cmd > Run as Administrator > Black screen
2. Type fsutil dirty query C: and press Enter. (Replace “C:” with the appropriate drive letter if necessary.)
3. If the output shows “The volume is not dirty,” Autodisk Check is disabled. If it shows “The volume is dirty,” proceed to the next step.
4. Type fsutil dirty set C: and press Enter to disable Autodisk Check for the specified drive.
