Missing disk space on local drive C:
Posted on 2009-12-18
I'm completely confused on where my disk space has gone. On a 40G drive C: all storage space gone and it should not be.
The environment is the machine is part of a windows 2008 server active directory domain with folder redirection enabled through group policy.
The my documents, desktop, etc. are being storaged on the server. The files are sync'ed with the PC and I also have offline files enabled.
I have cleaned, defraged , chkdsk /f the hard drive. Not to mention I deleted a lot of stuff off the my documents folder and also moved a considerable amount to other drives and media. Everytime this is done, more space is freed up, but within a few hours the freed up space is gone. The freed up space has sometimes been as much as 3G. We have not put files on the drive, but the space on the drive just disappears.
On the server and the local PC the 'my documents' folder is only about 2.5G. The sizes pretty well match when looking directly at the server drive and then looking at the 'my documents' from the user's PC.
In my latest troubleshooting procedure I've looked at every directory on drive C: to see what the disk space is for every folder. Everything seems normal, and in no way accounts for the entire drive when logged into the domain (what I did was look at every folder off of drive C: and viewed the properties). Each one looked good and nothing equaled 40G.
Now the odd thing, if I logged in as administrator on the local machine, not the domain, and did the same thing, looked at each subdirectory, everything looked just the same, except for the windows directory. The windows directory in the situation was 33G in size. Only when logged in locally does is show this size. When logged into the domain, the windows directory was much smaller, but I don't remember the exact size.
I'm about at wits end with this and I'm considering wiping the drive and reinstalling everything, but I really don't want to do that. Any ideas on what is going on? I've downloaded an application to show the largest files, etc and I'm planning on running it to see what I can come up with.
Last side note, there are about 50 pc configured this way and initially only one machine had this problem. Now I have another one that is showing the same symptoms, but not yet as bad as this.
