Thanks for the reply! I forgot to mention I have tried many different sata cables and ports on the motherboard

Hello everyone, I have tried looking for a solution here, but have not found one. I am on Unraid 6.9.2 I currently have a 3 drives setup (8tb parity + 2x 4tb) and I bought a new 10tb I want to assign as parity and transfer the 8tb to a normal storage drive. The issue comes when I try to assign the new 10tb drive anywhere: The dropdown will still show up as "unassigned", but the drive will also disappear from the unassigned devices. I tried starting the array this way to see if it would still pop up once started, but no, doing this pretty much makes the drive disappear from unraid. The only way to make the drive reappear is to assign a different drive on the dropdown I tried to assign the 10tb on. Other information that could help: The new 10tb drive does not have a readable temperature The SMART attributes and capabilities of the new 10tb drive can not be read I am not able to run a SMART self-test on the new drive The SMART status of the new drive is reported as "healthy" on the dashboard unraid-diagnostics-20220423-1103.zip
