So I have a dell poweredge r620 in my rack that I got recently, I put a 480gb SATA ssd in the first drive bay for a boot drive, ever since I put it in the server gives me a fatal error on bay 1 drive 0 (the ssd drive) however it still boots and everything, is there a way to get rid of this? Have I configured something incorrectly?

IT department are giving me an r630 however I only have a 400-500mm rack depth, I have tried the rails and obviously they don’t click in at the back as they are too long, do I need different rails? Or is there some other method?
