IOMETER not showing all disks or physical drives

So I went to do a benchmark of a new system and I noticed that IOMETER was only showing the C drive and not the physical disk or the shared cluster disks.

Googled this with no luck and then I did what I do with every problem I now run in to with win2k8 and I ran IOMETER as administrator which did the trick

not sure why the DAS drives were different from the C drive, but this fixed it.
