You run the Chkdsk.exe tool on a Windows XP-based or on a Windows Server 2003-based computer. You use the Chkdsk.exe tool to check a volume that is formatted to use the NTFS file system. However, you receive the following error message:
Correcting errors in the uppercase file.
This problem occurs when the following conditions are true:
- You use a Windows Vista-based computer to format the NTFS volume.
- You run the Chkdsk.exe tool on a computer that is running Windows XP or Windows Server 2003.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
When you use the /f switch together with the Chkdsk.exe tool, the Chkdsk.exe tool updates the file system to reflect the uppercase file that the current operating system uses. You can safely ignore the error message that is mentioned in the "Symptoms" section. The error message does not indicate a problem with the file system.
