I have 2 drives at 500gb each installed. I used the Windows storage manager to create a software mirror. Now I'm getting several disk full messages, and my C:\ reports having as few as 8MB free space left often. I then start uninstalling apps, clearing temp, etc., just to make room to keep using my system.
When I check the properties of all of the files in the C:\, it's reported as 113GB size on disk.
Seems to me that there is either some massive hidden file(s) taking up space, or that the RAID is simply reporting the incorrect values.
