I have a Dell latitude E6520 I-5 with my primary hdd Sata connectors broken. Primary hdd connection not working, I have also my caddy adapter with a sata hdd attached. Why can't I utilize my secondary sata connection as my primary hdd to continue my services. I've entered in BIOS it shows my secondary hdd which is attached to my modular bay. Upon booting it does not recognizes the secondary drive . I've been in this business for 20 plus years, this is a new one on me, Thank You

ANY HELP WOULD BE APPRECIATED
