I just tried this yesterday, because Drive 0 had errors. Unfortunatly the raid-system shows me than: failed
So I think, this wont work I don't know why...
I'm having this exact same problem - same board, same controller. I did one rebuild on port 1 and that was find and now needed to rebuild on port 0 and cannot boot. RAID BIOS will not rebuild either.
I had the same "results" over and over.
Read my discussion "Matrix Storage RAID1 repeatedly marks drive 2 as failed".
Over and over I marked the subject drive as "good" and rebuild starts.
I mentioned having tested and swapped drives to no avail.
After a couple of days the troubles start again and again.
You probably will get the same results.
I have dropped RAID on desktop boards entirely.
Both former RAID drives now behave.
The only thing is now each day one has to make a backup of the data.
System drive is done using Acronis each time new programs or patches are installed.
I feel happier now and it's costing me less time to safe-keep my data.
Thanks for the reply - though you're not giving me much hope...
Sounds like your symptoms were different, drives kept getting dropped?
I'm not able to boot or get to a point in BIOS where I can even add the drive... I may be heading to a non-raid desktop as well.
