Windows Vista Defrag problem

#1
So i started defrag a hour ago. It has been running for ages. And the strange thing is my hard drive space goes up and down. It starts at 52gb. Goes down in 100mb like 51.9gb...51.8 then goes to 53gb then starts going down and repeats the cycle. Why?

Did you try the things I suggested when you asked this question originally?

As to your question why your losing some HDD space... It's probably to do with Shadow copy storage as a small portion of your HDD is given over to storing shadow copies (usually around 15%). As the default defragger (which in my opinion is awful, slow and a complete waste of time) moves files around between the two then it may look like some has gone missing.
To resize your shadow storage check here:
Resizing Volume Shadow Service Storage - Vista

note: Don't go any lower than 900MB otherwise you may encounter problems..

Yup, it definately has it, unless you've turned it off....
If you go to this site here: TweakGuides.com - The TweakGuides Tweaking Companion and download the vista tweakguide it will give you all the info you need on resizing and what it actually does.. Plus many more things vista, an excellent read
You'll need a PDF reader such as adobe or Foxit..
