Have you checked the raid with Disk Utility?
Do both drives show up in System Profiler?
Mike, I sitting here with my jaw on the floor. This is so strange and I have you to thank... I think! Here's the deal. I've not touched the RAID drives since submitting my case... and I had just repeated all my tests before submitting my question to you. As far as Mac Finder was concerned, the RAID and individual drives that compose that RAID ... did NOT exist. Nada. So, I'm thinking, "What good is Disk Utility going to do if the OS can't even see these drives?" Well I plug them in and launch Disk Utility. There sitting on the home screen of Disk Utility are my drives. I had done NOTHING but lauch the utility. No first aid, no repair... nothing. I'm surprised, then Norton kicks in and starts scanning the drive. I launch Finder and there they are! THANK YOU. I feel like I've been duped by some parlor magic ;-) , but what I can I say it worked! THANKS!
Double checking everything now. I'm going to reboot and make sure they are stable and I can repeat this on a reboot. If that works, I'll get you paid right away!
OK but still check it
Mike... I'm astonished and amazed. Easiest fix to what I thought was going to be a really thorny issue. You da man!
