  1. Set pagefile size to 0
  2. turn off hibernation -- powercfg -h off
  3. disk cleanup (cleanmgr.exe)
  4. Defrag
Karl, if your theory is right, that would mean that the MFT gets moved somewhere along the way. The only actions in your list that could possibly do that are #s 3 or 4 - although I doubt that.

whs,
This is not a theory. I've done it.
Of course, after making the changes and before defragging then one needs to do a complete power down / power up sequence.

Sorry I used the word "theory". If that let you shrink more space, I wonder how the MFT got moved - that's all. Because normally the shrinkage bumps against the MFT that sits somewhere in the middle of the partition.

Please help!
In the last couple of days I've done considerable testing in this area.

The most probable cause of your problem is that Win7 has put a "unmovable" file at the end of the partition.

The only truly unmovable or unremovable category I've found is the MFT (Master File Table).

My 1st suggestion is to download, install and run three times (sometimes once is not enough and the 1st time will take longer), DeFraggler from the same people who have given us CCleaner and Recuva.
Defraggler - File and Disk Defragmentation - Free Download

This program is free.

This is going to get somethings out of the way for you. Very useful with this program is that by simply clicking on the Analyze button and after the Analyze if finished, right-click on the last thing shown.

Let me know what that shows and if after the defrag the situation is any better. Only if the MFT is the very last thing shown is the situation dismal.
Defraggler color codes the MFT for you.

I always move this by defragging with something that works.

I use XP to defrag my W7 Partition .. Haven't tried any other 3 parties.

noyb,
I really appreciate Defraggler's visual presentation of the drive. Give it a look-see. It's free, it works, it doesn't mess anything up. It isn't the fastest but I guess we can't have everything.

Possibly, The trick is to defragg W7 when it isn't running.

i've always run defraggler from within Win7. Maybe I should try it from the command prompt and safe mode but don't really see that buying me anything.

If the shrink button is grayed out, there must be another problem. It works even if you have no space at all to shrink. It just comes back to tell you that there is no space for shrinkage available. Are you sure your partition is not a dynamic partition?

Karl, you could always try that on some "dormant" data partition. I wonder what order of magnitude that will help - if any, because the defrag makes you gain only a small percentage of space.
