Wll, I finally got some time over to test things. I'm beginning to think that I have narrowed it down to what the problem is.
- Tried with resetting CMOS again and entering the settings again. Result: Detecting array...
- Yanked the power supply to both discs. Result: Boot error.
- Supplied the no 1 disc with power. Result: Detecting array...
- Supplied the no 2 disc with power. Result: Got into the RAID Utility where I got an error since it only finds half of the array.
- Reconnected the no 1 disc with another power connector. Result: Detecting array...
- Reconnected both discs and exchanged the SATA-cable for the no 1 disc. Result: Detecting array...
- Gave up...
Now, I've gotten some suggestions that it is the mobo that might be faulty (or at least parts of it) but after conducting these tests I'm beginning to think that it is the no 1 disc that is the issue. What makes me confused is that that disc shows up in BIOS and in the POST before I set the system to use RAID, so the disc itself SEEMS to be functioning. But still something fails. Has the data on the disc that tells the system it is part of a RAID array been messed up? If so, what to do then? Or is it possible that the order was messed up last time I rebuilt the computer (even though I marked the disks)? If so the question is, why did it work a while and then sieze?
Tried to contact the ASUS support, but they don't do telephone support on mobo's. Bas*$£#¤s...
Any further ideas are accepted with gratitude!
