One of my drives failed so i replaced it with a brand new drive and get the message "Unmountable: Unsupported partition layout".
I formatted the drive but that does nothing, after formatting i still get the same message. I placed the drive in my windows pc, did an extended smart test and everything is fine and the drive works in windows.
I tried a different sata cable, a different sata port and nothing works. I am getting desperate with this, this should be a simple plug and play operation.
Did a short smart test in UnRaid and that completed with no errors.
Hope someone can help me with this.
