What kind of damage / defect does your hdd show - Is the damage of logical or pysical nature ?
In case of an physical damage to your hard disc drive, Do-It-Yourself-Actions in order to try to repair the broken drive somehow, do fail in most of the cases. Professional labs frequently do receive storage carriers like hdds which already have been opened by the clients. Equipped with fingerprints, scratches on the magnetic platters inside of the disc, etc. For professional companies thease kind of failed repairs are more or less a big problem.
Improper attempts by customers and /or hobby rescuers to repair with the purpose in mind to enable the functionality of the disc drive again, can lead to the result that the rescue probability is even more worse for a data recovery lab, than it was before.
This results from the fact, that many users who do face a data loss scenario don´t know the difference inbetween logical and physical damages to hdd. It happens very often that users try to recover data with use of rescue software from a disc which isn´t even recognized in BIOS of the computer. Nevertheless, in such scenarios, the customer started systems on boot CDs and tries by a corresponding recovery software to salvage or carve something from a hard drive that is physically simply not present for the PC or laptop and not even existent.

1. Hard disc is not recognized by the BIOS of your PC / Notebook causing the error message like "No boot device found"
2. In case that the drive is no bootable device: - External or 2nd internal hdd is not recognized by the operating system
3. Drive is making a clicking / clacking noise or even a scratchy noise

Further more it takes an indepth knowledge about the exact funktionality of file systems and organisation.
2. Headcrash of the hard drive
In case of an headcrash scenario affecting the drive, nearly in most of the cases of falling damages, not only the magnetic platters and the read write unit of the drive will be harmed, also the data logic and the firmeware of the drive can be damaged.
