Article ID: 971234 - View products that this article applies to.
On a computer that is running Windows XP, you run the Dfrgntfs.exe tool to defragment a hard disk. However, the defragmentation process does not finish successfully. Additionally, the Defrag.exe tool crashes. In Task Manager, you notice that the CPU usage for the Dfrgntfs.exe tool process increases to 100 percent and stays at that level.
This problem occurs if the Defrag.exe tool encounters a 0-byte attribute entry in the attribute list.
