From the sounds of it your drive is having problems ;-{

If you really need whats on your drive you don't want to mess with it as anything you do right now will likely make it worse!

OK what to do here? First you'll either need to find someone with the skills to replace your drive and place your old drive into an external case so you can access it after you get your system up and working.

Or, you can do this your self! Here's how:

* You'll need a new drive and this series has issues with the drive cable so I would replace that as well. Here is the parts you'll want [product|IF163-041-2|MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable - Apple P/N 923-0104. As for the drive I would recommend this one: [http://www.seagate.com/consumer/upgrade/laptop-solid-state-hybrid-drive/].
* You'll need a set of tools like this one: [product|IF145-072|Classic Pro Tech Toolkit] and you'll need either a case to hold your original drive or this: [https://www.startech.com/HDD/Adapters/USB-3-SATA-adapter-cable-with-UASP~USB3S2SAT3CB|Startech 2.5" SATA to USB adapter]
* Follow this IFIXIT guide to open your system to remove your old drive and put in the new cable and drive: [guide|5120|MacBook Pro 13" Unibody Early 2011 Hard Drive Cable Replacement].
* Lastly you'll need to connect your system to a network to then prep and install a fresh copy of OS onto your new drive using Internet Recovery. Here's an Apple T/N that explains it: [https://support.apple.com/en-us/HT201314|About OS-X Recovery].
