Here's what I don't want to happen.
Let's say (hope not), DR company said HDD failed and needs to do platter swap, but due to the plates we can't recover your data.
OR,
Due to the plates, that'll cost you $3000 (instead of $1000 HDD with no plates). Because it's very difficult task and bla bla bla... don't wanna hear the rest.
Don't misunderstand that I want to or going to do platter swap and all that.
I don't have the tools and knowledge about it. End of story.
Basically, just a precaution. Is that bad actually?

No company should undetake any work you dont approve of so a definitive diagnostic can be given by a professional, and you choose a DR company based on reputation, size, and experience in the market, then you have a good chance of getting all your data recovered. You choose a small DR outfit who operate from the backroom of a PC shop then you will likely not get your data.
There are many experienced and skilled engineers here, choose one and I am sure they will be willing to help you, and you will be able to tell just how exprienced and skilled based on posts made displaying obvious knowledge inthe field.
And as for the price, well you get what you pay for. DR is not easy, it is time consuming, it is difficult, it often requires the use of specialised equipment and tools, and many times requires the use of spare parts, and this is the reason you will not get your data recovered for $100, and the reason why anyone offering it for an extremely low price is not likley to have these tools, parts, knowledge and skills.
You want to be sure your data is in good hands, make sure it goes to a professional!
