Successfully swapped the bad drive out and rebulit array. Many thanks for the help Len

Went through the shrink array procedure and did the new config part (retaining drive assignments) and Disk4 went away so looks to be OK now.

Disk2 and Disk3 are empty. I could replace Disk1 with original and then could shrink the array and then use one of those removed disks assigned to disk4 to sort out the issue?

At the moment I only have 4 sata ports so not sure how that has happened? Any way around this? I did a new config after this cropped up initially and the symptoms didn't change.

Disk4 is unassigned. The minimum slot count is 6 so I assumed that that is why Disk4 shows up? There are only 4 disks showing on the dashboard.

New user on trial version of Unraid so very possible something obvious! Version: 6.12.0-rc6 I have the following setup:- Parity 2TB, Data Array of Disk1 2TB, Disk2 1TB, Disk3 1TB, Cache 500GB + 500GB Raid0. These disks were what I had around and will be replaced with a new group of drives once I have familiarised myself with the system. Disk1 is showing increasing read errors and so I want to swap this disk out. My replacement disk is also a 2TB unit although not the same model. I have followed the procedure set out https://docs.unraid.net/unraid-os/manual/storage-management#data-disks To replace a failed disk or disks: 1. Stop the array. 2. Power down the unit. 3. Replace the failed disk(s) with a new one(s). 4. Power up the unit. 5. Assign the replacement disk(s) using the Unraid webGui. 6. Click the checkbox that says Yes I want to do this At step 5. I get a "wrong" under Disk1 and a red cross. Down at the Array Operation area I get "Stopped. Invalid configuration". The Start button is greyed out and "Too many wrong and/or missing disks. I never see step 6. I have tried this several times always with the same result. So, what am I missing? Thanks Len tower-diagnostics-20230531-0926.zip

OK, looks as though my first post was black holed! Thanks Len

I am a new user and posted a new topic that was marked as needing approval. I get all that but it's been several days now and I'm not sure my post was even registered or has it just disappeared somehow. If it is still waiting for approval then it would be helpful to see some sort of reference to this in my activity log. At the moment it just shows zero. I don't know if I have posted or not? Thanks Len
