Disk Management only allowing 20GB partition out of 946GB

    Recovery at the end is normal for a EFI/GPT system. Mine looks like this:

    Do you have media to recover your system if needed?

    All I can suggest is what I would do if I encountered your situation. First I would delete the partitions you created. Then shut the system down and do a cold boot.

    After that, check the drive again to see if Disk Management will allow shrinking the partition any further. If it will not, I would think about extending it a small amount and see how that goes, then check the shrink again.

    If it helps, I would then shrink the drive all at once, not in pieces. Then add the partitions starting from the left in the unallocated space.

    Disk Management does have a Rescan option in the menu, you could try that.

    If you use Explorer to look at the C: partition's properties, under the tools and optimize button, my partition shows as being Optimized automatically and done weekly. Perhaps the third party software you are using to defrag is causing conflicts.
    Ok, so i deleted all partitions i created and extended C drive back to its original state. Extending the drive is not available as an option when i right click on the C drive. In fact, even after deleting the first 100GB partition, C drive would not extend to absorb the unallocated space, i had to delete a 200GB volume before it would extend. I did a rescan, it changed nothing. I did check the properties of C, factory settings are set up weekly, and like i said, i used Win8.1's preloaded Disk Optimizer to defrag.
    Now this is what i see... seemingly half of my HDD unavailable to use, just as i experienced while partitioning.

    I have since completed a system restore to the day i purchased the PC, and still i am seeing the exact info as the image above, only the size of available shrink space is now at 941283.

    Any ideas from here?

    Can you download and run Defraggler from Piriform, just run 'Analyze' then show us what you got.

    Now click on those two blue blocks on the lower left and find out what they are, they could be your bottleneck.
    (I'm bettin it's your anti-virus)
    (then maybe run the defrag - see what it does.)

    Defraggler seemed to do the trick. I love CCleaner, but ive never used any of their other programs... looks like ill have to look into their other offerings. Thanks so much for all the advice and tips everyone!!
