SYMPTOMS
On a multiple-processor computer with two or more programs that access the same files by using the CreateFile (or another) file function, one of the programs may receive a STATUS_FILE_CORRUPT_ERROR response and generate an error message similar to:

FILE.TXT -- Corrupt File

The file or directory \dir\temp is corrupt and unreadable, please run the Chkdsk utility.

However, when you run Chkdsk.exe, no file corruption is found.



CAUSE
This behavior is caused by a timing issue in the NTFS file system when both programs attempt to access the same file at the same time. This timing problem causes a STATUS_FILE_CORRUPT_ERROR response to be returned erroneously to one of the programs.
