Thanks Roberto ... no biggie - just a cold that we blame on the ever-changing weather of spring around here ... just didn't want to share with the other kids :) I'd say you are good to go ... showing RAID 1, State is Ready (with green check mark means healthy), both drives are Online with no failure predicted; in terms of a hardware RAID controller, this is exactly what you should see when everything is working like it should.  
I have a Dell Poweredge T610 with the following specs:OS: Windows Server 2008 R2 - 5 CAL | Processor: Intel 56XX 2.13 GHz Quad Core | Hard Drive: 2x 250 GB - Raid Capability: 0,1 | Memory: 8GB and I added 2 DELL HARD DRIVE 500GB SATA  hot swapable (front panel) for extra storage.I can see a 500 gig on the Server in Computer  Management but cannot see the other 2 - 500 gig hard drives.  How can I make them visible?Also Once both drives are visible I would like to use one HDD as storage for images from a DM system. My goal is to use the second HDD to mirrored the first one for fault tolerance. How can I do that? Thanks for your help.
