1TB of HDD space missing completely

My laptop has a 2TB hard drive, but a few months ago over half of it completely vanished. Windows explorer shows that my C drive is now only 911GB. I believe the issue came about after I uninstalled Ubuntu (I dual booted for a while) and I thought that perhaps the space just didn't get reallocated properly so I checked in disk management and didn't find an "unallocated space" block. I tried error checking my hard disk, but this didn't fix it either. I have no idea how to fix this problem

I tried WinDirStat. It showed me the contents of my C partition, but not the space that is missing (not a part of any partition)

Maybe a screenshot will shed some light,

Disk Management - Post a Screen Capture Image

Did you check the shadowstorage - WinDirStat will not show that.

Used is 6 GB, max is 10 GB. I don't think that is the issue

You don't have a 2TB disk, you have a 1TB disk, same size as mine.

It was 2 TB when i bought it, that's the problem lol
