Well, I thank you for the helpful links.
I'm not too concerned about rebuilding the RAID. Like, I would like to be able to do it, but if not, I'll live. It was my gaming drive. It just means reinstalling all the games, readjusting the settings, and starting over. Which is no big deal. Starting my games from scratch is no biggie.
I'm mostly worried about how to handle this. Like you said, I think the RAID controller on the board died. What I am going to do when I get a chance is take the computer apart, swap the SATA cables from good SATA ports, clear CMOS, and see if that makes the board able to recognize those ports. The method behind that madness is, if one of the SATA cables died, while both ports were recognized as being part of a RAID, this could have jammed something in the BIOS / firmware. Or maybe it is just one port that died, resulting in jamming the BIOS.
Yeah I know, this is all highly unlikely, but I'd like to rule it out. I just don't have time at the moment to dissect the computer to get into the nightmare of cable management and move around those SATA cables.
Assuming the controller is just dead, I guess the next thing to do is buy a RAID controller. I can fit one in my first PCIe slot. It's a PCIe 2.0 x1, which means it has a theoretical throughput of 500 MB's.
If I put the two drives on my SATAII RAID, using the other built in RAID controller, SATAII will cap these two drives.
The only problem with a RAID card controller, is that I have to remove my wireless networking card, and I can't put it on the other PCIe slots because they'll choke one of my two graphics cards that need to breathe. So I guess I'll try one of those USB wireless adapters. Besides, the one I have now doesn't work with Linux.
I think that beats buying a new motherboard. This is an Asrock OC Formula Z77. This thing cost $220 when I bought it. The only motherboard I'd consider buying right now is the Asrock Fatal!ty for $120. Wait... that assumes they even make one with an LGA 1155 socket for this 3770K CPU.
So I definitely think buying a RAID card for my PCIe 2.0 x1 is the way to go here.
And I have a feeling the dead port/s is my fault. When first installing this board, I put the wrong end of a SATA cable in there, had the hardest time getting it out, and heard something crack, or crunch, and thought for sure I broke the SATA connector. Maybe I just damaged it, and it took 2 years to finally die.
I was mostly checking on here to see if there was something I hadn't thought of.
