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.

  • I can't see the usage in storage manager, but it reports the disk size correctly as 463GB. With 113GB of disk used, you'd think I'd have plenty left to play with. – derjur Nov 14 '11 at 15:54
  • Are you certain your partition is actually using all of the mirror? Sounds likely to me that it is not. – Garrett Nov 14 '11 at 19:46

I was obtaining the values for Size On Disk by selecting all of the folders on the root of C:. It wasn't picking up folders that I don't have access to under that account. Found a nice 380GB folder in there.

Mystery solved.
