Macbook Pro SSD - Mid 2010

[avi1292]

Hello all, I'm new to these forums and I needed some help with my MacBook. I recently got a new Toshiba HDTS225XZSTA solid state drive and I was trying to run both of them on my mac by swapping it out with the superdrive. I did all the hard ware changes and also formatted the hard drive externally to be able to be read on mac, Mac OS Extended. Once I put it all together, the ssd doesn't show up anywhere. Not in disk utility, not in "about this mac", not in bootcamp, nor in the "option" screen at start up. I cannot seem to find a solution to this and I need some help. I tried taking it out again and reformatting it but it just doesn't budge, help??
