No, if you check a NTFS disk after some work, it's heavily 
fragmented. As you fill it and work with it, it becomes more and more 
fragmented.

The best way to defragment a NTFS drive is make a backup to other 
device, format the original and recover the backup. It take less time 
and device don't suffer. I do it monthly with the data disks and 
performance grows espectacularly (near x4 on sustained  file read).
