@Tom-Elliott I’m on r7410 at home currently, I just deleted this host and tried to network boot and do a full registration. It worked fine lol.
However all it saw was sda when I do have sdb there as well. They are still configured as RAID 0. I’ve learned a little more about this particular RAID card because of one of George’s posts. It’s a hybrid card. It doesn’t actually present one singular drive to the OS, it presents two. But it does have it’s own POST and BIOS menu, and can create volumes and delete them, restore volumes and such… The card is like 6 bucks on ebay - and for what I do with it, it’s a great card. I’ve bought 3 of them lol.
