Asrock fatal1ty Raid Setup

   Hi, 

I've been trying to setup my disks with raid but run into a problem. I have 2 identical hitachi 500gb HDDs, and one Kingston 250gb SSD. 
I've enabled raid into storage options, and created new raid array with the 2 hitachi, saved settings but in the boot options I cannot see my SSD disk which already has an operating system. I played with the SCM settings also but it did not do any good. Anyone has any idea how to setup this 3rd disk to boot. 

Thanks. 

I will include exact MB and firmware in my next post (need to restart).

	MB is X470 Gaming K4 P3.50 Now I see when I enable the raid option that the ssd disk is listed as legacy, but when I select the scm option legacy only I cannot see the raid setup menu. Probably I need to format the SSD from and it will appear in the boot list. I really didn't wanted to do this. Is this the only option?

	The best option is to forget this mainboard RAID feature (in my opinion). Even if it will function, your RAID will only work with this mainboard and moving it to another system will be impossible (in the most cases). If you want RAID, use pure SW for it, completetely mainboard independent. The onboard RAID anyway is nothing else as a SW RAID, but with a complete unnecessary mainboard/bios dependency. Here is a discussion (also boot SSD, 2xHD as RAIDx) with the same problems: https://linustechtips.com/main/topic/782604-raid-on-ryzen/

	Thanks for your response. I'll think about it, I don't like the overhead processing that will be used for the sw raid, but then again I don't store files that often on those disks.
