What is Ntfs.sys and Ntfs.sys failed error?

Ntfs.Sys is a windows driver in a computer. This software program allows a computer to communicate with hardware or other connected devices. It means that the driver has direct access to an operating system’s, hardware’s, and other devices’ internals. It is straightforward to start and stop the driver from the Services menu in the Control Panel.

On the other hand, Sys is a file in the Windows file system and a Microsoft file. However, some cases where users encounter an error, such as NTFS.sys, are missing or corrupt. Most of the time, malware disguises itself as NTFS.sys, which also generates such errors. As a result, a user must inspect the NTFS.sys process on the system to ensure it is not a threat. As a result, I will cover “how to manually fix NTFS.SYS Corrupt error in Windows XP” in this article.

Error Drivers Ntfs.sys failed Or Corrupted

A user receives the following error message:

NTFS.SYS is either missing or corrupt.

It indicates that the NTFS.sys file is missing or corrupt. As a result, in this post, I will discuss all of the possible reasons.

The causes of this error:

Overclocking may also be a cause of this Windows driver file error. Any changes to bus or memory speeds may result in a problem with memory or other system settings, resulting in file corruption.

Heating Issue: One of the most common causes of file corruption is overheating. Sometimes, the processor heat sink fan isn’t working correctly, causing the corrupt NTFS.sys file.

Malware Infection: If the system holds any virus, the NTFS.sys file may become corrupted and continue to display this error message.

FAT 32 to NTFS Conversion: While converting FAT 32 to NTFS file system, there is a chance that the file will become corrupted in the process due to any reason such as an abnormal shutdown, power failure, and so on.

Memory or Hardware Failure: It is also possible that the system is suffering from a memory or hardware failure. Furthermore, it is not suitable for a system when computer memory suddenly fails. A user suggested resetting computer memory to solve this problem.

Fixing Windows Driver File Errors Manually

Various solutions are available to resolve NTFS.sys failed or corrupt errors that a user can try to resolve NTFS.sys error. They are all listed below:

Using the Recovery Console, replace Ntfs.Sys.

    • When the message “Press any key to boot from CD” appears, the user must insert a Windows CD into the computer and run the CD.

    • Following that, a welcome screen appears, and you must press R to proceed. Select R to use the Recovery Console to repair a Windows XP installation.

    • Now, from the Recovery Console, enter the installation number for which a user wishes to log in.

    • A user must have the administrator password to access the command prompt.

A user must enter the following DOS command into the command prompt:

    • These commands rename the existing NTFS.sys file so that the new one can be easily replaced and is corruption-free.

    • Then, type command and Enter:

cd:i386ntfs.sys drive:\windows\system\32drivers\copy      

    • Where cd is a drive letter for a CD-ROM drive. This drive is where you install Windows XP.

    • Now, remove the CD and press the Quit button. Restart your computer.

As previously stated, the hard disc can also be one of the causes of NTFS.sys file corruption. As a result, a user can use this attempt to perform a disc check by running CHDSK from the Recovery Console.

After that, launch Command Prompt and enter the following command:


In this case, /R is a command-line switch that will automatically repair any error found on the hard disc. However, CHKDSK can take some time, so be patient and prepared to wait. After resolving all the problematic disc errors, restart the computer.
