When you run your tool of choice to see the disk space is it running as administrator? If you use something like defraggler it will show all the space and whatever is eating the space will be fragmenting as it grows. It's not unusual for an SBS box in this situation to have 50GB+ of IIS log files for all WSUS activity.

Sounds like you have some large files in areas that you don't have permission to. This is not that unusual in 2008. Some of the areas to check:- * Problem Reports. Those things can be huge. Open "Problem Reports and Solutions" and then click on "Clear solution and problem history". * Recycle Bins (have any folder redirection going on? Users deleted large files sitting in their recycle bins on the server). Turn on viewing of protected operating system files and have a browse around. * IIS Logs c:\inetpub\logs\logfiles\ then check each folder in there. If you haven't browsed into those folders and clicked on the security prompts to get permission to view the contents then a folder size query WON'T show the actual size of the folder/s. * C:\windows\temp Another option is to use the File Server Resource Manager and run some reports on large files etc. That will show up anything no matter what permissions are set.

Hi, I have a Windows 2008 server with a 100GB C partition. It has 8GB free, meaning 92GB is in use. However every disk space tool I use shows that only 34GB of data is on the drive. I've tried clearing the shadow copies and that freed a few GB. Any idea where the other 60'ish GB may be lurking ?
