Server indicating more space taken up than there actually is

[nocode99]

I have a Windows 2003 server with a Raid-5 (6x146gb) split into 2 partitions. The D drive is 370GB usable space and when I look at My Computer or look at the properties of the drive, it indicates it's using 120 GB of space. I've ran several utilities and the most I'm getting is 20 GB of used space. There was a bad drive that I've replaced and I've ran sdelete twice (before and after the drive replacement). I plan on P2V the server and I'm afraid it's going to tell me that it's occupying 120 GB of space and I'm at a loss as to why this is happening. The disk utilities scan system files too and there's no page file or hidden recycle bins occupying data. Anybody seen this issue before?

You might have a virus that is hiding files

See if TreeSizeFree gives you a different opinion or points to the culprits (disk hogs).

Are there file shares on the partition? could it be shadow copies?

I found the culprit. It's the System Volume Information (system folder on the root drive). I adjusted the maxsize of the system restore storage (by using the vssadmin command) and cleared up a lot of data.

Thanks,
