Summary
The article addresses the "Windows has detected file system corruption on local disk C" error, which usually occurs due to a damaged file system or corrupted Windows system files. This error prevents users from performing a system restore until the issue is resolved. The article provides an overview of the error, including common error messages, and offers several methods to fix the problem and restore system functionality.
Facing the “Windows has detected file system corruption on local disk C” error can be frustrating, especially when you need to restore your system. This corruption can be caused by a hardware-related ailment or by a program that gets corrupted that accesses the i-node or superblock information directly. When this issue arises, it prevents you from performing any system restore point until the problem is resolved. In this article, we will explore several useful ways to solve this error and get your system back to normal.
This error message generally appears in one of the following forms: “The local disk (C:) has errors. Windows has detected file system corruption on local disk (C:). You must check the disk for errors before it can be restored. “
These errors are common in Windows 10/8/7 and are mainly caused by a hardware failure or software error .
If a sector malfunctions, the data it returns may differ from what was written, potentially corrupting the file system. If your SSD is old, consider replacing it. You can use a tool like CrystalDiskInfo to monitor its error rate, indicating imminent failure. SSDs can only be written to a limited number of times per block , so they may start returning errors after a few years. Manufacturers overprovision extra blocks to replace worn-out ones, extending the SSD’s lifespan, but these eventually run out too.
A Windows software (file system driver) error could cause corruption, but this is rare due to the maturity of filesystems. However, a serious crash or power loss during filesystem modification can still result in corruption. Some filesystems use journaling to mitigate this, but it can still occur.
Here are three simple and effective methods to fix the Windows has detected file system corruption on local disk C error:
When the error message pops up, there is usually a link that says: “Check the disk for errors.” Clicking this link allows Windows to run a disk check and repair the issue for you. Follow these steps:
1. Click on the “Check the disk for errors” link.
2. Allow Windows to run the disk check and repair any issues.
3. Reboot your computer and try to perform the restore again.
If this initial attempt does not resolve the issue, move on to the following advanced solutions.
Corrupted Windows system files are a common cause of the Windows has detected file system corruption error. The System File Checker (SFC) tool can scan and repair missing or corrupted system files. Here’s how to run an SFC scan:
1. Right-click the “Start” button and select “Command Prompt (Admin)”.
2. Type
sfc /scannow
into the Command Prompt window and press Enter to run a full system scan.
If you see the message “ Windows Resource Protection did not find any integrity violations,” it means there is nothing wrong with the Windows system files. If the issue persists, proceed to the next solution.
Bad sectors and corrupted file systems can also trigger the Windows has detected file system corruption error. The CHKDSK utility can check and repair these issues. Follow these steps:
1. Open Command Prompt as an administrator.
2. Type chkdsk C: /f and press Enter.
3. Allow CHKDSK to scan and repair the file system. A corrupted file system occurs when its internal structures are inconsistent.
This can be caused by hardware failures, such as malfunctioning sectors on an SSD, or by software errors, which are rare but possible due to serious crashes or power losses.
If your SSD is old, consider monitoring its error rate with a tool like smartctl and replacing it if necessary.
