Lost disk space in Windows 7, cannot find the missing
My hard drive is complaining it is low on disk space, but a strange thing seems to be happening: Explorer reports 10Gb of available space (on a 120 Gb hard disk), chkdsk in the command prompt does the same but if I use a disk space tool such as SpaceSniffer or WinDirStat, only 50Gb of data is found.
My guess is that there somehow is a hold on a large block of disk space (but that's just a guess) because of a prior very large (40 Gb) download attempt that didn't complete.
There isn't 40Gb of files on the drive (hidden or visible), yet Explorer insists that something is there. How can I claim back this hard disk drive (without formatting my hard disk)?
SpaceMonger is providing a clue, reporting four unscannable folders which add up to 43Gb:
- C:\RRBackups
- C:\System Volume Information
- C:\Windows\Csc\v2.06
- C:\Windows\System32\LogFiles\Wmi\RtBackup
Does anybody know what these folders are for, and how I can claim back at least some space?
Restore point claims about 4Gb, so that doesn't seem to be the main problem.
Solution 1:
C:\RRBackups: Weekly image of the whole drive (?!?) http://www.howtogeek.com/forum/topic/thinkpad-rrbackups-and-disk-space
C:\System Volume Information: System Restore and Previous Versions.
C:\Windows\Csc: Client side cache, used in Offline Files.
No clue what the last one is.

The disk space losing problem was because the program "Lenovo Rescue and Recovery" on my Lenovo T410i laptop, uninstall the program from control panel will get the space right back.
