DEFRAG (greeen bits)

[John]

At one time when I ran defrag I only used to have one or two green
(unmovable) stripes. I now have 6 - is there anything I should do about
this? I like to keep things optimised.

Nothing to worry about...

you can do more
defrag with a freeware
from microsoft.com
called pagedefrag.

I would be interested in seeing a Disk Defragmenter report. 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. Do this before running Disk Defragmenter as it
is more informative.

Hope this helps.

There is a posibility that you are using a Windows managed pagefile
which means that the size of the pagefile is dynamic. In that case,
your pagefile could be on a couple of different sections of the hard
disk. When I do use a pagefile (which is almost NEVER), I have it set
to a fixed size and the whole file is allocated at one time. If the
hard disk has been properly defragged right before this, you get one
file that is contiguous.

You will also get very slightly better performance from the pagefile
since it is not having to move all over the hard disk to find sections
of itself.

What is also interesting is that sometimes the fairly large (default 15%(?)
of the disk space) so-called, "reserved MFT zone" becomes quite small, OR
vice versa (suddenly reappears again in the middle of the drive, back at
15%).

I haven't figured out why it sometimes changes this way (after doing
restores, backups, etc).

It's 12.5%. And it gets smaller as needed, i.e., it will get smaller
if space is needed for other files. The only permanent thing about it
is that the MFT reserved space is the last to be used for storing
files.

Well, I was talking about a HUGE change in its size, when I still have tons
of disk space.

I mean, if you look at the defragger legend map, sometimes the "reserved MFT
Zone" is only a few clusters in size, and at some other times, it looks like
its the good old, 12.5% of the total disk space - depending on its mood.
In ALL cases, I have PLENTY of disk space (about half of the disk is free),
and that hasn't changed.
