The are one or two companies in Irkutsk I could recommend, but you might be from Myanmar so that might be a problem.
Where are you from and what kind of HDD (Hard Disk Drive - system or external or additional internal one) are you talking about? Does it still spin and just can't be recognized by your Mac?
If it still spins, there is software, that is able to recover data from still spinning HDDs.
SO if you could further explain the problem you have with the HDD of yours, we might be able to offer alternatives, that are not as expensive as recovering data companies are in this day and age.
I am in United State, the Hard Disk is Internal MacBook, the problem is not spinning and why I don't have a Backup is because before a few days at Wall mart parking somebody open my car a stole every thing in the car including my External Backup hard Disk Drive.
Unbelievable I loose my backup and the next day My MacBook stop working.
