I had similar error to this while trying to shrink a 931GB partition to about 600GB when the partition had 555TB used.

The attempt to shrink directly to 600GB failed as did an attempt to shrink to 610GB.

I then chose the mid point between 610GB and 931GB = 731GB and was able to get past the simulation check. If this works, I will keep trying mid points until I get to the size I need to get to.

Ok. So what I eventually did to resize it was to resize in increments

First resize, shrink by 5GB, then tried by an additional 10GB, 25GB, and 20GB until it got down to the desired size.

Not entirely sure why gparted gives an error when it tries to do it all at once, but seems like this strategy works.

Probably the same technique that @TylerH used (by setting shrink size to 10% larger than before)

I didn't provide full background on my approach. I was resizing a partition at the time I ran into this error. After successfully resizing I created a new partition with the space created by the resize. Hence my wording. But that should be unrelated to the issue here.

So, in resizing, i added 10% more space compared to my previous attempts. Which was successful.

I was able to solve this problem today.

  1. After experiencing the issue, I ran a chkdisk, a thorough disk cleanup and then defragemented.
  2. When I tried again to create the partition I added an additional 10% of the stated minimum size of the partition (according to gparted). So it was just under 110% of the minimum size because I wanted a nice round number.

Perhaps one or a combination of these items will help solve the issue for you as well.

Create the partition? Did you reformat or something? Did you use gparted or the windows? –  arcyqwerty Jul 5 '12 at 14:05
