Defrag - List is empty

[Frank C]

My Defrag reports four total fragments but doen't list them
2 MFT fragments
1 Fragmented folder
1 Page file fragment
Is there a way to identify these problems and correct them?
Thanks

Open Disk Defragmenter and click on Analyse. Select View Report and
click on Save As and Save. Now find VolumeC.txt in your My Documents
Folder and post a copy.

We don't know what defragment software you are using. Windows' built-in
defragmenter does not defragment every file, by design.

Thank you for the replies.
Leonard, I am using the Win XP defrag program
Here is the result as requested by Gerry

Cluster size = 4 KB
Used space = 25.82 GB
Free space = 123 GB
Percent free space = 82 %

Volume fragmentation
Total fragmentation = 0 %
File fragmentation = 0 %
Free space fragmentation = 0 %

File fragmentation
Total files = 73,555
Average file size = 508 KB
Total fragmented files = 0
Total excess fragments = 0
Average fragments per file = 1.00

Pagefile fragmentation
Pagefile size = 1.50 GB

Nothing to worry about apart from the MFT being 98% full.

You drive is defragmented and I see no cause for concern there.

If the MFT grows beyond 100% of it's preallocated space, then it will
fragment. One option is to run a boot-time defrag to defrag the MFT
(and the page file as a bonus) after it has become fragmented.

Option 2- resize the MFT before it's filled up to prevent it's
fragmentation in the first place.

For either/both these options, you will need a third party tool such as
Diskeeper Pro; AFAIK the windows defragger cannot defrag or resize the
MFT. There are free trial versions at their site....so you can try it
for free.

You have one folder fragmented and that is the MFT and that is in 2
fragments which is normal. The MFT is never listed as a fragmented file
which cannot be fragmented. The MFT is added to after the completion of
the defragmentation process. The comments of Sareth about what happens
when the allocation of space to the MFT exceeds 100% do not coincide
with my observations. The allocation simply is increased in size. On
some disks you will find the MFT table in three fragments but more often
in two. You have really no need for a third party defragmenter.

Thank you for the response.
I have done some additional reading on the subject of the Master File Table.
One source said that the operating system would increase the space as needed;
http://www.pcguide.com/ref/hdd/file/ntfs/archMFT-c.html

I conclude I can only increased the size of the MFT at the time that the
disk is formated.
Since I am not going to do that my course of action is to do nothing.

This paragragh in your link contradicts " I conclude I can only
increased the size of the MFT at the time that the disk is formated."

As more files and directories are added to the file system, it becomes
necessary for NTFS to add more records to the MFT. Since keeping the MFT
contiguous on the disk improves performance, when an NTFS volume is
first set up, the operating system reserves about 12.5% of the disk
space immediately following the MFT; this is sometimes called the "MFT
Zone". This is a substantial chunk of real estate to reserve, but bear
in mind that it is still usable. Regular files and directories will not
use this space until and unless the rest of the disk volume space is
consumed, but if that occurs, the "MFT Zone" will be used. Eventually,
if there are enough entries placed in the MFT, as it expands it will use
up the "MFT Zone". When this happens, the operating system will
automatically allocate more space elsewhere on the disk for the MFT.
This allows the MFT to grow to a size limited only by the size of the
volume, but this fragmentation of the MFT may reduce performance by
increasing the number of reads required for some files, and the MFT
cannot generally be defragmented.

My interpretation is that the user cannot set the MFT size.

You are right.

I stand corrected.

It is no longer possible to set the MFT size manually in any of the
latest versions of the third party defragmenters. I know for a fact
that you could manually upsize (but not reduce) the MFT in the 2007
version of DK Pro, but looks like it is done automatically in the
latest version.
