When you use one or more programs to move files and to rename those files, you may experience both of the following symptoms:

  • You occasionally receive the following error message:

    The file or directory is corrupt and unreadable. Please run the Chkdsk utiltity.

  • If you run the Chkdsk.exe tool, the Chkdsk.exe tool does not report any problems with the hard disk or with the file indexes.


This problem may occur if you are running Microsoft Windows Server 2003 on a computer that has multiple central processing units (CPUs). A race condition may occur where two separate threads rename and move a particular file in the NTFS file sytem at the same time. This problem occurs because NTFS incorrectly determines that the name of a parent folder does not change when NTFS opens a file. For example, one thread might rename a file at the same time that the other thread moves the same file. NTFS then tries to remove a link that no longer exists to the file. Therefore, NTFS generates the error message that is listed earlier in this article.
