Thanks. We'll let you know when a new response is added.

Assuming you are running the Windows defragger, unfortunately, particularly with a badly fragmented hard drive, it doesn’t always do a complete defragmentation in one pass. (I’ve seen it take as many as 3 passes for that defragger to completely defrag a drive.) In addition, that defragger will not defrag the page file.

To get a complete defragmentation, you have to use a 3rd party defragger like Diskeeper or some such.

Also any open files (such as Windows itself) will prevent the disk from fully defragmenting.

===========
Your hard disk drive could not be defragged because there might be a problem with some sectors of the drive. It would be better if you will run the checkdisk utility first before performing the hard disk drive defragmentation.
