dfrgntfs (defrag) hogs the CPU cycles

By john ·
I'm running Windows XP professional installed on a new machine in April 2004.
Over the last 2 weeks, a program called dfrgntfs.exe is running in the background and taking up 99% of the CPU cycles. This is the disk defrag program.

I cannot stop it using Task Manager. It is not one of the scheduled tasks either.

Has anybody got a solution to stop this program?

This article describes the Defrag.exe command line utility that is included with Windows XP. The Defrag.exe command line utility is specifically designed for scripting and for use by system administrators. To defragment a volume using Windows, follow these steps:

1. Right-click My Computer, and then click Open.
2. Right-click the volume that you want to defragment, and then click Properties.
3. Click the Tools tab, and then click Defragment Now.
4. Click Defragment.
5. Click View Report to view the Defragmentation Report, which displays detailed information about the volume that you defragmented.

The Defrag.exe command line utility locates and consolidates fragmented boot files, data files, and folders on local volumes.

When you are saving files, the file is not necessarily saved as an entire file or folder in a contiguous space. The files are saved in the first available space on a volume. After a large portion of the volume has been used for file and folder storage, most of the new files are saved in pieces across the volume. When you delete files or folders, the empty spaces left behind fill in randomly as you store new ones.

You can find the Defrag utility, Defrag.exe, in the %SystemRoot%\System32 folder. You can defragment disk volumes formatted as FAT, FAT32, and NTFS. Defrag also works with Dynamic as well as Basic Disks.
