Thanks JorgeB - this worked and now have added the other drive in as well.

That’s really strange, the parity was wiped by Unraid so not sure why it was setup non-standard. What’s the easiest way to reinit the parity?

Hi All, I seem to be unable to add a new drive to my array, even though they are all the same size. The drives are all 2TB, and everywhere I look they are reported as exactly the same size. What I've tried (which didn't work!) - Re-formatting the drive - Re-seating the drive - Checking the "HPA" status - disabled on all drives I've attached some screenshots and the system diagnostics - anyone got any ideas? Array of 3 drives Array to add Disk 3 Error Cheers!
