Thanks JorgeB. I will do this. Can you recommend the best practice for doing this? I currently have all my SATA ports used. 4 on motherboard and 4 on my LSI-card. Is it safe to unplug one of the disks, reconnect my old disk, and copy contents to the new drive, or will i need the array with all the 8 disks, and then connecting this as the 9th disk? Then I must get an additional LSI-card. Was hopeing to avoid this for some time, but I might need to go shopping on ebay now. Thanks for your help and advice.

Yeah, and I also can see the new drive under the historical "Unassigned devices". I cannot remember this happening when replacing any other drive before. I currently have some 3-4 TB drives i replace when I have some cash to spend on new drive, so I have been doing this now for a couple of months (and drives), and it have always worked.....before now. Thanks for looking into this for me. Apprechiate it!

No, just replaced the old drive in WebGui with the new drive and started the array which kicked off a parity rebuild.

Hello, I had a drive which was working, but I'd figure I'd replace it as it started to get old. I did the following. Clean shutdown Replaced drive physically Powered on Unraid Replaced the decommisioned drive in the WebGui with the new disk. Started array with parity rebuild as Unraid suggested. The parity rebuild went for 17 hrs successfully. And now I'm having a fresh and new 8TB drive working, but it's missing all the data which was on the decommisioned drive. Any suggestions, or am I screwed? Thanks vault-diagnostics-20251006-1032.zip
