Hello everyone, I purchased a 4TB WD Red drive, and installed it into my server. UnRAID detects it but when I start the array it will say " Unmountable: Unsupported partition layout" on that particular drive. The other drives in the system are 2 2TB WD Red's and a 250GB Samsung Evo SSD. I'm using a Dell H200 raid card and I've attached the diagnostics of the server.
