I have an SBS2011 server that is a single VM on Vsphere 5.0. I am looking at the "D" or data drive on the computer. In computer, it reports to be 269 GB with 23.8 GB remaining. When I run WinDirStat against it, the total space used is 87.5 GB. However, WinDirStat reports the drive as being 269 GB with 23.8 free. When I select all folders (including hidden) and look at the size, I get 63.6 GB. I am attaching a screen-shot too. The Data drive is a thinly provisioned drive and can hold up to 270 GB.
Has anyone seen this or know what's going on here? I am lost.
