February 5, 20233 yr I had one of my drives on it's way out so I moved all the files from it to the other drives and physically switched it out for another drive. I added the new drive to the array and started it. Unraid automatically started running Rebuild on the drive, I assumed to rebuilt the empty prev drive. Once finished, my new replacement drive is still "Unmountable: Unsupported partition layout". I checked to format unmountable drives, hit format. Page refreshes, nothing occurred. Retried, same. 1. What should I do now to get my new drive working in unraid? 2. Why did Unraid rebuild an empty drive? 3. Why did Unraid not format the drive before rebuilding it? 4. Were this to happen unprepared to a drive that wasn't empty.. What should I have done differently to avoid data loss?
February 5, 20233 yr Community Expert Solution You're probably on unraid 6.11.2 which had issues formatting drives. Update. 2 minutes ago, profzelonka said: 2. Why did Unraid rebuild an empty drive? When a drive is replaced it gets rebuilt, that's the whole point of parity. The system doesn't even know whether there is something useful on the filesystem or not.

February 5, 20233 yr Author Ah, thanks, updating now to 6.11.5. So in theory, if I were to stay on 6.11.2 and one of my drives failed and it fails to format the new drive before the rebuilt, the data is lost?
February 5, 20233 yr Community Expert You could do another rebuild after upgrading and have it work, there might be another solution but if so I don't know about it. But yeah - as a server admin it's kinda important to follow the changelogs and stay on top of updates if problems are found
