We did successful data recovery jobs when ontrack claimed that data was unrecoverable. Last case, what they wrote to their customer was (translation from Polish):
- electronics firmware damage
- eccentric misalignment of HDD components
- damage of heads read-write element which fell onto the platter surface causing scratches of magnetic surface; scratches of bottom platter surface make data recovery impossible
What was more important, and what pissed one of our clients off, was that ontrack wrote that it is impossible to recover data from this drive. They wrote that data recovery is not possible in any lab – not in Poland, nor in any lab in the world (!). And yet... we recovered it.
Our client was very disappointed and decided to write a testimonial which we published online. What was next – "unknown" trolls started to discredit us and started personal attacks on different forums. When regular people saw what is going on, what the client wrote and what trolls are doing they said it is obviously bad PR.
Then ontrack's PR manager showed up and wrote that they will change their default letter (!). After all these years, after many successful recovery jobs done by us after ontrack, they decided to change their default letter that they are the best and there is no one who can recover data when they failed.
Publication of simple testimonial worked. We will see in the future, when another jobs after them will come, what kind of letters they are sending :>
I'm not saying this is your case – but it may be. Second opinion is always good.
PS: As a proof - scans of documents. Of course our client agreed on publication of these. They are in Polish tho

Good luck with your recovery!
