I have a 900GB HDD, but for some reason it will only allow me to shrink like 2500MB of it. In the past, I could shrink to my desired size, but for some reason it is giving me a problem now. I have tried defragging it with PerfectDisk, but I actually think doing that made it even smaller. I have also tried using cmd diskpart but that fails too. Heres a pic:
Thanks for any help!
