I have cloned one of the incorrect drives to the new 18TB drive and ran now I am going to do the next step from your instructions: What is read only mode, I see maintenance mode, but not read only mode?

Thank you for your response, I am still learning unraid so I have some questions on how to proceed. The 10TB and 4TB drives will need to be fixed based on your last response. To test that process out, I can clone each drive and test the fix first. Can I clone the 10tb drive to an 18tb drive and test the fix there or do I need to clone a 10tb to a 10tb? I have not used DD before, is this the correct format? dd if=/dev/sdd of=/dev/sdb bs=64M conv=noerror the 10TB drive is listed as sdd, the 18TB drive is listed as sdb.

ok and what about the 4tb one?

here is the output

Update: We did update the bios and we did find in the updated setting the place to turn off HPA (Bios to HDD). We verified that it is disabled. We then started up unraid and the 2 drives were still unmounted. Attached are the latest diagnostics. tower-diagnostics-20250327-2212.zip tower-diagnostics-20250327-2212.zip

I was just checking the HPA link you gave us, that works fine, but the actual removal guide links for the HPA does not work anymore. Im just going to throw this out there but we have a Gigabybye GA-EX58-UD5P motherboard and we checked and we could not find an HPA setting in the bios, We are running original firmware. There is new firmware that we are upgrading to in order to see if that fixes things.

no thats the whole issue, the two drives are not mountable even though I changed nothing with them

What I did was I did a new config for the sever. I had read somewhere that when adding new drive you had to do that so thats why the server was able to start again.

We found how to set up AHCI in the bios and we have turned that on and disabled IDE, have rebooted computer and have re-run diagnostics (attached) and we still have two drives that are unmountable (see screenshot). tower-diagnostics-20250326-1711.zip
