Had the same issue. I'm using 1TB Samsung HDD as secondary drive which I partitioned into two equal halves in my Hp Compaq DC7900 running windows 10 Pro. One of the partitions which I store my video files before editing had 180 GB of free space and midway through the defragging process It reduced to 162 GB and on getting to 80 % my free disk space reduced further to 92 GB. I stopped the process and had to copy the entire contents of that partition (about 284 GB) into an external drive, format it and transfer the video files back into the formatted partition to recover about 92 GB lost free space.
How to get back my HDD free space after defragment?
