Virtual disks show hard drive capacity in one area but not the other

I have a Dell PowerEdge T710 server with 7 physical disks present using the integrated PERC H700 RAID controller.  There are 2 300GB and 5 600GB SAS HDD with 6.0 GBPS throughput.  In the OpenManage Server Administrator, under Connector 1 > Enclosure > Physical Disks, 2 of the 600GB drives I just installed show "Non-Critical Warnings". I know this is due to the drives being non-certified , but I was told that they would work.
As shown in the attachment the Volume List in Disk Management on the server shows data drive (D:) capacity is 1116.75GB while the Graphical View at the bottom shows 2048.00GB. The 2048.00GB should be the correct amount.
If I go to Computer on the server and look at the hard drive capacity, the D: Drive only shows 1 TB of available hard drive space. Is there any way to get the additional TB of hard drive space to be accessible by the server or should I just replace the drives with certified drives?Server-Drive-error.PNG

disk 2 is MBR; needs to be converted to GPT to use anything over 2tb then extend the volume using the remaining 185gb
then see if the sizes match on top

Thanks for the quick response Seth,
The problem is the missing approximately 1 TB of HD Space. I could live without the 185GB.

It's 1116.75 GB on the top portion of the screen shot vs. 2048.00 GB on the bottom portion of the screen shot. When I originally installed the 2 600 GB hard drives I did go in and extend the volume to add the capacity which shows in the bottom portion. It's just not showing as usable space on the server.

Windows didn't extend the NTFS filesystem, it sometimes forgets to do that. There used to be a tool called fsextend that fixed this problem but now it's built into diskpart...

http://support.microsoft.com/kb/832316 (ignore the hotfix part, just skip down to the more information section:

DISKPART> list volume

  Volume ###  Ltr  Label        Fs     Type        Size     Status     Info
  ----------  ---  -----------  -----  ----------  -------  ---------  --------
  Volume 0     D                      Removable     27 PB
  Volume 1     E   DATA_VOL    NTFS   Partition   2000 MB  Healthy
  Volume 2     C   Windows     NTFS   Partition   4001 MB  Healthy    System

The Diskpart utility's extend filesystem command extends the file system on the volume.

DISKPART> select volume 1

DISKPART> extend filesystem

DiskPart successfully extended the file system on the volume.

DISKPART> exit
