Hi, wiklendt.
The Vistax64 forum where you posted your question simply relayed it to the
Microsoft public news server, a part of Usenet, where I am reading it in the
microsoft.public.windows.vista.file_management newsgroup. Your forum will
now, I hope, relay my response back to you. If you'd like to cut out the
middleman and post directly to this newsgroup, just click here:

You have obviously learned a lot about how your computer works. We just
need to fine-tune some of it. ;<) (The Help file in Disk Management is
chockfull of good information, but it covers a lot of topics (GPT disks,
dynamic disks, etc.,) that most of us don't need to get into, and it is
organized as a reference, so we can't just read it sequentially like a text
or tutorial. I highly recommend investing some time (and money?) in a good
reference like the Vista Resource Kit from Microsoft Press or Windows Vista
Inside Out, by Ed Bott and others.)

You didn't explicitly say, but I assume you are using Disk Management in
Vista. (DM is one of my favorite utilities and it gets better with each
version. Vista added the "Shrink Volume" function.) When Shrink Volume is
successful, it leaves some "Free Space" in which a new volume can be
created, but it does not automatically create the new volume. DM doesn't
know if we want to create one big volume or several smaller volumes in that
space. To create a new volume there, we right-click in the Free Space,
choose New Simple Volume, and follow the wizard.

You apparently have an "unmovable file" near the end of your newly-shrunken
drive. You need to identify that file and delete it, or Copy it to another
spot, closer to the front of your drive. It's not always easy to identify
which file is where on a volume.

The page file is usually deleted and recreated anew at each reboot, so it is
seldom unmovable. But, to be sure, you can use Advanced System Properties
to set it to NO page file temporarily, just long enough to let defrag claim
that space. After changing to NO page file, reboot, then open a Command
Prompt and enter Dir C:\ /a and look for the file pagefile.sys. It should
be about 4 GB in size and should show that it was created today at the time
you PREVIOUSLY rebooted, not your current reboot. You should be able to
easily delete it, although you may have to remove the System and Hidden
attributes first. Don't worry about losing it; Vista will recreate it
automatically as soon as you change the Advanced System Settings and reboot
again.
You might need to go through a similar exercise to delete C:\hiberfil.sys,
which should also be over 3 GB. This is what holds the memory dump while
Vista hibernates, so you will have to temporarily turn off hibernation in
your power options.
> if i set *no* page file, what effect will this have on my system?
Vista uses a page file, even if it has unlimited RAM; that's just the way it
works. So be sure to return your setting to System Managed as soon as your
repartitioning is done.
Post back if you have questions.
