Thanks Trurl Everything went fine.

Hi Hoping some more experience unraid users can give me their opinion on the following procedure and advise if I have missed anything or made any errors. I want to shrink my array by removing 3 old hard disk drives (a 500 GB and a couple of 1 TB drives) and also replace my current 8 TB Seagate archive (SMR) parity drive with a faster non-SMR 8 TB drive and add the archive drive as a data disk to the array. Pre-clear new 8 TB drive. Move all data from the 3 old drives I want to remove. Remove the 3 old drives from any shares they were included in. Take screen shot of my current drive assignments. Stop array then go to Tools – New Config – Retain current Config – Apply. Unassign the 3 drives I want to remove. Unassign current SMR parity drive. Assign the new non SMR as parity drive Assign old SMR parity drive as a data drive. Don’t click check box for Parity is valid. Start the array. Wait for parity to build.
