SYMPTOMS

On a Windows Vista-based computer, the Universal Disk Format (UDF) component may set the Irp->IoStatus.Information field to a size beyond of the End of File (EOF) flag of a file when a paging read IRP is completed. Therefore, file-system filter drivers that depend on the result of the Irp->IoStatus.Information field run incorrectly.

Notes

• This problem rarely occurs.
• The expected behavior is described in the More information section.
