Looking at properties for the drive shows the entire drive using the 149GB (or 148GB some rounding going on).
TreeSize says C:\(OS) is 120.8GB. So that's my question where is the ~28GB? Computer shows it all accounted for on C:\(OS) but TreeSize does not.
Is it restore points? Are restore points included in the Computer's properties but not in TreeSize? That could explain it but as mentioned I have 30GB and I'm "missing" 28GB.
I'm not necessarily trying to reclaim lost space just trying to understand where it is and most importantly why I seem to be losing 1-2GB a day. And the 1-2GB a day is not going to C:\(OS) as that number (currently 120.8GB) doesn't increase by 1-2GB a day.
If the above 30GB is what your restore points are set for just wait and see if the 'Lost Space' exceeds 30GB. Should be able to see it today.
Depending on the size of your data, 1-2GB per restore point is within the expected range.
You have a lot of free space so that isn't going to cause you any problems.
Or you can reduce your system restore capacity to 15GB and see if you get the 13GB back, and then you can see if it keeps expanding.
If you don't need the space you can set it back to 30GB after you find out if this is where the space is going.
It will not do any harm testing the drive first as recommended by myself and others previously.
Better to know if your HDD is in good health than suddenly finding out wasn't, later.
It is a known fact that HDDs can and do fail at any time, even when new.
Let us know what you decide to do.
