2nd HDD on caddy hangs whenever i tried to open it?

I bought a caddy and an ssd. I insert ssd to my main sata port and load a windows and works fine then i put the hdd in caddy and put it to the optical disc bay sata when i open Explorer The partitions of hdd shows normally but when i open it and try to open a folder inside it, it can't be open and it just hangs and needs to hard reset everytime. When i try to run crystaldiscmark it just don't do anything and hangs. What could be the problem.
My Laptop model is Lenovo G50 - 70.
