A bit of a long story...
I have an ASRock AM4 B550 Pro4 motherboard with 2 Samsung 1 TB SATA drives. I also have 2 Samsung M.2 NVMe drives.
Step 1 - I followed the instructions to setup the M.2 drives in a RAID1 configuration. Installation went great and I was able to use that array a number of times.
Step 2 - Now I tried to re-do my bootable partition into a new RAID1 using my 1 TB SATA drives. I could get them to load but every time I tried to restore the partition, they became unbootable.
Step 3 - I stopped trying to restore the partition and just do a file copy and not replace duplicate files. I was finally able to get that completed but for some reason, not all the files got properly restored and I just was going to put that off to fix.
Step 4 - During this whole several day ordeal, I have my C drive RAID1 working and my D drive RAID1 working at the same time. Now I just wanted to reboot to make sure it's stable. Bad mistake.
Step 5 - RAIDXpert2 in Windows now said array 2 was offline. It could only see the 2 SATA drives in the C array (array 1) and not either of the M.2 drives. I went into Disk Management, where Windows saw the 2 M.2 drives as 2 separate drives (0 and 1) but not as one drive. The RAID 1 C drive did show as one drive.
Step 6 - I tried every combination I could think of by deleting the array 2, initializing the drives, moving one SATA data line as the motherboard manual said that the M2_3 slot (which I am using) shares a line with SATA 3, 5 and 6 ports so they were no longer shared.
Finally I just gave up and reformatted the 2 M.2 2 TB drives as "D" and "G" and both are working fine.
How do I get these 2 M.2 drives to work again as RAID1 and be seen by RAIDXpert2 in windows? The BIOS version likes the drives very much and so does Windows it seems.
