part of the hdd where you put the SATA connector the L shaped plastic part where the pins are at on the HDD broke off. I just plugged it in with the plastic piece in the SATA cable.
If the contacts touched correctly, this should work. You can also try CAREFULLY supergluing the plastic back on, but it requires a very steady hand.
Its possible either your BIOS for some strange reason isnt recognizing your drive, or the drive's board is dead. If the data is THAT important, I have one final solution, but it is a bit difficult.
You can buy an identical hard drive (SAME MODEL NUMBER!) that is BROKEN/FAILED on ebay for cheap. Then, take out its system board, DESOLDER its BIOS chip, DESOLDER your current drives BIOS chip. THEN, solder your current drive's BIOS chip into the new system board.
Then install the board into your HDD, then your HDD should be fresh and new again.

If its THAT important, you can get companies to do this for you, unless you're good at soldering PCBs. BEFORE you do anything like this, try your HDD on another system. If all the connectors on the broken "L Shaped" part are still ok and straight, superglue the plastic back onto the broken part carefully and try it in a new pc.
Heres the good news: Its most likely (75-80%) that your data is still ok on the drive, if you really need, you can get a data recovery service to get your data back.
If I am correct, I am assuming it broke like this?
