    So I have an a1278 Macbook pro from 2012 and i decided i was going to take out the superdrive. I did the install and it all went smoothly. Although, when i booted the computer, it does not show the second hard drive in the disk management app. I know the drive works, and the superdrive worked beforehand. Is there any way that i can force it to check for the new hard drive?

    Did you format the drive on a USB cable before putting it in?

    That's good. If it's mechanical can you hear it spinning up? If it's not showing the connector may not be seated correctly.

    Best case the cables loose worst case it's damaged. I would take the bottom off reseat the cable and hit the power button to see if the drive spins up.

    Have you tried the drive on the other bay to see if it spins up?

    Do you see the second drive in System Information?
    Check under the SATA tab. You should see both SATA drives listed there.

    Then faulty cable, faulty adapter or faulty drive, need to swap bits to work out which. Rule the drive out by moving it to the main drive bay and booting off an external drive or off a bootable USB key

    nope, no drive is viewable under the sata table. How much does a cable run for?
