I recently upgrade the hard drive space in a Dell Power Edge 2600 Server. It has a PERC 4/DI controller and is running Windows 2003 Standard Server Service Pack 2. About a year ago, I installed a new SCSI drive (146 Gb) and made a RAID 0 volume for additional data space. I recently installed 3 other SCSI drives (146 each, exactly the same as first drive) and reconstructed the RAID 0 to RAID 5. The server successfully reconstructed the RAID and Initialized it. When I boot into the controller BIOS, or access it through the Dell RAID Array Manager, I can see the RAID 5 volume and all drives are online. However, when I look at it in Windows Explorer, it still shows the total volume to be 146 Gb (just like it did when it was RAID 0). I'm at a stand still and would like to know if anyone could give me a little assistance in getting Windows to show me the same total volume as the RAID controller (the RAID controller shows 400 Gb).
