You install an M.2 SSD card in an M.2 slot on a motherboard. When you boot up your system, you discover the DVD drive no longer works. What are likely causes of this problem? Select two.

a. The DVD drive SATA connector is disabled.

b. The DVD drive cable is loose or disconnected.                                                                                  

Explanation:          

When using an M.2 SSD card in M.2 slot on the motherboard, SATA ports are disabled. This is because sometimes these ports break out of their connection or link. So check SATA connectors and check if the SATA cables are connected to the SATA port properly. Also sometimes that DVD drive does not show up when you boot your system after installing m.2 SSD card because of the loose or disconnected cable. This cable can be unknowingly unplugged so all the cable connections must be checked in order to resolve this issue.
