This is the first time I have encountered this problem with Ubuntu 12.10

I am trying to restore data from an external hard drive using TestDisk 6.14. There were read problems so I aborted the app.

I did manage to get about 80gb recovered to a temp directory in my Home folder. when I tried to delete this temp directory, I had to open Caja as root from a terminal (I am using the MATE DE) in order to have the permission.

Once the temp directory was deleted there should have been about 95gb free on my system partition. But it's only showing 35gb free. I know this is incorrect as I checked the total amount of freespace on the partition before restoring data from the external drive to my system partition to make sure there was room. There was 95gb free.

I used the direct delete function. So these files should not have gone to the trash folder.

I can not seem to open the trash folder as caja root. I get an error saying the file can not be accessed. So I can not tell if the files are somehow stuck in the trash.

  • Can anyone tell me what might be happening here?
  • Why is there apparently now about 60gb of "invisible data" taking up space on my system drive?
  • How do I access the root trash folder to make sure it's really empty?
  • If this "invisible data" is not in the root trash folder than how do I find it and delete it?

Hope someone can help me with this.

Have you looked in the /lost+found folder? –  Jos Nov 8 '13 at 19:02
    
Yes I looked in lost and found and it's "empty" –  Jason Nov 8 '13 at 19:19
    
I got only 1 idea: these files are in use. rm removes the name of the file as seen in the directory tree. It will remove all references after the files is no longer in use (and then space becomes free). –  Rinzwind Nov 8 '13 at 19:21
    
I don't see how those files could be in use... I have rebooted the machine at least 3 times since I noticed this problem and checked that there aren't any processes running that may be using the files... and I think if a process was using 60GB worth of files it would be causing my CPU usage and memory to max out. –  Jason Nov 9 '13 at 18:35
    
Anyone have any other ideas... I need to free up this space. How do I see and delete files that are 'invisible'? –  Jason Nov 26 '13 at 8:03
