Correcting errors in the uppercase file.

Cause


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.
This problem occurs because of the differences in the uppercase file between Windows Vista and the earlier versions of the Windows operating systems.

Status


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

More Information


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.
