    Also, I'm thinking the magician may have hidden your drives. Do they show up in the defrag view? FYI, some say they could manage partitions after temporarily enabling defrag; however, in my case, I have defrag turned off and I could still shrink partitions if needed:

    I cannot open anything related to disk defragmentation. Not when I right click on my drives and not when I select the service from control panel. I click, but nothing opens.

    @alphanumeric, my disk is not GPT.

    Let's see if I can make sense of diskpart now.

    Appreciate the help, guys.

    Again no luck, it comes up with the same error as I mentioned in the first post. (but in Dutch, naturally)

    i have exhausted this on a samsung laptop normal hdd, it will not shrink because the mft files are placed at the opposite end of the partition to the windows 8 files in the "c" drive.

    samsung support cold not grasp the problem, if you use a 3rd party defrag that shows a coloured block chart tou will see the mft files at the very end these are not moveable preventing shrinking of the partition.
    only complete reinstall using a w8 dvd will fix it.

    I'm glad it worked for you, I used it in the past when windows disk management wouldn't do what I wanted to do. Free is good too.

    FYI, Since I also have a SSD Samsung 830 128GB in another PC. I was curious why you couldn't shrink so here's what I found.
    1. Ran Shrink volume from Disk Management, after querying it said I have ~70 GB available but it will give an error message:

    2. Ran Perfect Disk Pro, it showed a snapshot of my SSD with files scattered at the end of the drive

    3. Ran Perfect Disk Pro again to Consolidate Free Space

    4. Now I can shrink it by 50GB

    In conclusion, If files on your SSD are scattered, specially your pagefile.sys and hiberfil.sys are sometimes placed at the end of the disk, you will not be able to shrink it. In addition, if you get an error and was not able to shrink using Disk Management then there must be something wrong with your SSD, you might want to take a look at updating the firmware etc...

    If Optimize drives service is disabled partitions shrinking won't work in Disk Management.
