Just recently did a Server 2011SBS Standard Migration from Server 2003 SBS. Everything is going fine at this time, expect the C Drive is running out of disk space rapidly. We allotted 200GB of space for the C Drive which is only housing the Operating system. All folder redirects and Exchange, shares, and user files are on the other partitions of 1TB. When I choose all data on the C drive and choose properties it only calculates 45GBS of usage. Now I know there are folder permission not allowing me to see certain data, but with the 200GB drive, we have 15GB free! So I am losing 140GB of data that can not be found! Please help, the Page File is also on an alternate partition. Does anyone have any ideas? I did read that VSS may chew it up, but VSS is not running.
