Windows Server 2003 reporting wrong free disk space information

[Gilbert]

I have a Windows 2003 server and I have a F: drive that is reporting
incorrect free space. In My computer, it shows 68 GB capacity and only about
200Mb free.

If I select all the folders on that drive and go to Properties, it only
shows 54GB used up. I ran chkdsk and here's what I get:

C:\Documents and Settings\Administrator>chkdsk f:

I ran it with the /F option but I haven't rebooted my server for it to run.

1. I ran Disk cleanup to get rid of temp files, trash, etc.
2. Disk Quota is not turned on
3. I read the article on Microsoft's site
http://support.microsoft.com/default.aspx?scid=kb;en-us;303079
but it didn't help me understand what's happening on the server

this method is unreliable, as it only enumerates files and folders you have
access to, and is likely to skip a lot. Even when you are Administrator on
the machine. Do not trust this method.

this is a good method !! good indication of your actual free space.
Which in this case is (16518 * 4096) / 1024 / 1024 = 64.5 MB

This is VERY low, consider a serious clean up, including moving certain data
to another volume.

Rgds,
