Windows 10: Invisible unallocated space.

I wanted to shrank my F Drive by 40GB, but suddenly it was stuck for a long time so i stopped virtual disk service from services.msc but when i checked the size of my drive it was less by almost 40gb but there was not unallocated space, but when i used a few 3rd party applications they showed my real drive size but also showed that my drive was using 40gb less even in disk management shows the same. is there any way to fix it, and the unallocated space is only 12mb. i dont want to format my disk and lose data.screenshort of disk management of Drive F:https://imgur.com/a/SL1ZyWV

Unallocated Space to C Drive

Hi Travis,

It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

• In Disk Management, right-click on (C which appears next to the
  Unallocated partition.
  
• Select Extend.

Let us know if you're able to combine the spaces after following the steps above.

Regards.

Was commenting on the pic in post #21. Not suggesting anything. It just looked like the step you were doing was incomplete.
