Professional data recovery may be your only option at this point. They can even physically move the platters out of the drive and onto a new setup in a cleanroom, and try to recover your data that way. It's quite involved, and success depends on the failure mode.

At one time, I was quoted $1,000 for a failed spinner which had irreplaceable photos, and even though I was ready and willing to pay, they still couldn't recover anything for me.
