Does anybody know whats going on here?

This machine is running Windows 7 Pro and the drive is mapped to a target on Windows Home Server v1.
The drives are 2 x 2TB WD Reds in good health, when I only had 1 x 2TB drive in there, the status bar was as expected.
I know it doesn't really matter, but it would be nice if it worked.
Thanks
