Disk Defragment

When I run disk defragment I get a message that says there are some files on
my computer that cannot be defragmented.

Hi

There are certain Windows files that can't be defragmented - which ones are
you referring to?

Do you have at least 15 percent free disk space?

[[After you defragment a volume, you can view the defragmentation report to
see the results. The report includes a list of files that remain fragmented
(having two or more fragments). Some reasons that a file might remain
fragmented include:

• The volume lacks adequate contiguous free space to defragment all files.
Disk Defragmenter requires at least 15 percent free disk space to completely
defragment a volume.]]

The Windows defragmenter will not defragment the MFT and paging file if
thats what you mean. For this you will need to use a third party tool.
If its a case of imcomplete defrag, make sure you run chkdsk and then
defrag in safe mode. (also u need 15% free space for it to do a decent
job)

My problem is similar. after running disk defrag many times, I always end
up with one rather wide "fragmented files" red bar. (It is 2 or 3 times the
width of most "Free Space" white bars). ?Is there any way to get rid of this
Red bar? Is there any way to determine what it represents?
Thanks,

Please go through Vogel's post in this same thread again. Did you try
defragmenting in safe mode/ran chkdsk/do you have 15% free space? Tried
using a third party tool?
