SYMPTOMS
On a multiprocessor system, you may receive the following error message:

The file or directory \directoryname\filename is corrupt and unreadable please run the CHKDSK utility

Running CHKDSK does not reveal any file corruption.



CAUSE
This issue can occur if multiple I/O Request Packets (IRPs) attempt to modify a file simultaneously. The error message appears if an IRP is returned with the error code STATUS_FILE_CORRUPT_ERROR. This behavior occurs only on multiprocessor systems that are using the NTFS file system.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

This problem was first corrected in Windows 2000 Service Pack 2.



MORE INFORMATION
The following sequence of events produces this error:


 * The first process opens a file.
 * The second process opens the same file.
 * The first process gets file attributes.
 * The second process renames the file.
 * The first process closes the file handle, resulting in cleanup. This IRP will be returned with STATUS_FILE_CORRUPT_ERROR.
