Less Space After Defragging

Why is this?
Is there a way of fixing this?
Thanks for your time.

In my case, there is this "System Volume Information" that keeps consuming more and more of my space and I cannot defrag that data.
How about you guys?

I don't know what happened, but I ran regular disk defragmenter for awhile, and all my lost free space came back. Weird stuff. I could never find that lost space anywhere. Two separate disk space analyzers said I only had 195GB on my hard drive.
Wow, that's weird.
I have an idea, though. Is there some undefragmentable files there that are entitled "System Volume Information"?
I hear that when a non-Windows defragger program modifies the disk, Windows saves information for backup. I heard that there is a way of shutting this of, but I don't remember how.

Anyway, turn it off before defragging and back on again when done. Be aware of that turning it off deletes all restore points so be sure you have no settings you want restored, files you have deleted that you might want back or have changes you might want to undo. This ensures you have more free space when defragging, less unfragmentable space locked by the restore points and Windows doesn't go bananas during your defrag session by creating a heap of huge restore points.
To turn it off in Vista go to Control Panel->System and Maintenance->System->System Protection. Uncheck the checkbox next to the drive you want to defrag.

I have put together a 'Help Sheet' gleaned over time, I find it has been useful to some folk
who are constantly monitoring their 'Free Space'
By setting a Max size to the 'Shadow Storage and System Restore file, and then clearing out all the old restore points except
the last new one will give you a truer reading of space free.
Some or all of the elements may be of use,
Please note although these items work on 'My machine' I cannot guarantee they will work on others, use is at own risk.
Instructions to Control Vista Used Space problems

Press OK. Choose Create a Restore Point then click Next. Name it and click Create, when the confirmation screen shows the restore point has been created click Close.
Next go to Start Menu > Run > type...
Click OK, Disk Cleanup will open and start calculating the amount of space that can be freed, Once that's finished it will open the Disk Cleanup options screen, click the More Options tab then click Clean up on the system restore area and choose Yes at the confirmation window which will remove all the restore points except the one just created.
To close Disk Cleanup and remove the Temporary Internet Files detected in the initial scan click OK then choose Yes on the confirmation window.
