Sadly there is little you can do here.

If you can locate an second exact same model and size of your hard drive and you have the skills to carefully remove the logic board from the good drive to place on the bad drive you might be lucky. If you do get it working make a backup ASAP as it may not last.

OK, no luck in finding a second drive to swap the parts out. Your last option here is sending your drive to a data recovery service so they can try to recover your data. I must warn you it will be expensive!
