Fragmented Pagefile

[Guest]

I have pagefile set to 768/768. I use PerfectDisk7. PD7 only shows the
pagefile contiguous right after a reboot. After that it is scattered all over
the disk. Raxco responded this way:

More than likely this is due to a setting in your registry which will cause
your operating system to recreate the pagefile upon every boot.

This is a feature of WindowsXP, though not everyone uses it.

This only recently started. Have been running SP2 for quite sometime now.
So, I don't think that is necessarily the problem. Just installed it on
another system. Will see if it happens on that system as well.

I set pagefile to 0 0 thenreboot into safe, defrag then reset pagefile

You should at least investigate the advice given by Raxco before you
dismiss it.

The file will be recreated un-fragmented provided the disk is properly
defragmented in the first place. With Perfect disk you set this up by
asking for an *Offline* defrag and rebooting for it to be done. First
in tools - Advanced make sure it is set to allow it to optimise files
needed for start

Quite unnecessary, see my post. This was not a good answer at all from
Raxco - typical junior uninformed tech support

Yes, definitely a Knee-Jerk, First match or throw off suggestion.
Many times Perfect Disk users don't fully understand how to setup/run
the product. Many don't enter Tools, Advanced Configuration & toggle
the Optimization to "Let Perfect Disk Handle all the Layout.Ini" and
leave it at the Recommended setting.
With it on the recommended setting, you're not getting the full benefit
of PD & Prefetch/Layout.Ini.

I never used "perfect disk" but I know that clearing your page file at
shutdown will double or maybe triple the time it takes your system to
reboot,been there done that.

This may be of interest to you?

Alex -
I performed the Offline Defrag. Additionally, there is another strange thing
happening as well. The pagefile does not remain in the same location as it
did before. Being (you) familiar with PD, you know that they place the
pagefile adjacent to the directories in the center of the disk. However, now
it may find itself at the end of the HD, at the end of the data, or adjacent
to the directories. In these recent placements, they have all been
UNfragmented. Either PD is not able to keep/lock the pagefile in it's place
or WinXP is doing something with it. For a while after Offline Defrag and
SmartPlacement Defrag the pagefile was adjacent. I rebooted and did an
Analyze (did nothing else but use my system for a few hours in a normal
fashion) and the pagefile was at the end of the HD, did another reboot and
the pagefile was at the end of the data. NO changes were made to the system.
I have run several spyware/adaware programs, have SpySweeper running all the
time, along with NAV2005, and ZoneAlarm Pro. All show system as clean.

Any more ideas? This all seems kind of bizarre to me.

Detail of how it works out positioning I don't know. For more you had
better hope Greg Hayes (MVP but of Raxco) comes round

It does not really matter in detail where the page file is, as long as
seeks to it are not made worse than needed by using a second partition
way down the primary hard disk. VM management does not search down it
sequentially but has information in memory of where on disk pages are
located, so goes direct to them

Following is the latest, and probably the last response from Raxco. Never did
hear from Greg, always Jason Clairborne. Is there a registry setting?

"I really have no idea what is going on with your system. It would appear
that
your pagefile simply moves about on the disk without any reason for doing so.

In the nearly 15 years i've been working on computers i've never seen a
situation like yours. I really do suspect that some registry entry has been
set
that is manipulating the creation and placement of the pagefile on this
system.
What that registry entry is, i cannot say."

no problem with the disk. chkdsk is OK.

oops...sorry for my previous bottom post...so you don't have to scroll,
here it is again

I'm suspecting bad clusters with the os remapping the file...give
chkdisk a go with repair

I emailed and requested that Greg Hayes look at this as Alex Nichol and you
suggested, but there has been no answer. I have lots of screen captures of
the analysed layout showing the movement. I have run chkdsk and a surface
test. They are all OK. Also, the analyse from within Windows is quite fast,
from online it takes over 20 minutes - just to analyse.

My system is working fine, with no outward signs of problems in anyway.

I have a copy of Diskeeper and am thinking about running it and seeing what
happens. Nothing to lose, but time.
