I've recently have built a gaming computer, and everything was fine. But when I was downloading mods to my SSD (A 500GB Samsung one) i checked how much space i have left on it, and i looked at my HDD and out of nowhere from about 2TB free space it went to only 900 GB available. The only things that i have downloaded there will be in the screenshot. As I said, all of the stuff that take up a lot of space like games i have on my SSD. I've tried searching for issues, or cleaning it and still nothing.
