can head crash be a misdiagnosis?

[beginner]

my hd is seagate 7200.11
it was bricked, then unbricked by me,then it was recognised for 10 min, i got 5gigs and it lost recognition in mid of copying, within a short time , no partition was found then hd wasnt recognised.
it gives 3 clicks at start and than stops clicking.(i think it spins ok) clicking were at the very end only.

My Question is:

is there any chance the data recovery i sent the hd just open it, saw the clicks and said "head crash". is it possible hardware screwd up and the wired reacting head makes them think its a head crash?
in other words, can somone say head crash even if they dont see a visble scratch?

When we talk about "head crash" means the MR Heads´s touch magnetic coating that could be means , "media damaged, example the typical head crash" circles over the media" wich damaged the MR Heads and the coating too, the most times, its on the land zone . some times its recoverable by experience, to diagnostic the professional DR should be check microscopic damages, into the MR Sensor´s, and coating too, and check the most typical "syntomphs" of head crash, even by the sound at some brands its possible to determine if was head crash or no. we are doing some researchs into that to be possible if getting directly signal ´s from the disk to determine if its or no head crash, still on research.

how do you know which part is damaged?

checking the internals is now absolutely neccessary before working further on this drive. This MUST be done in a class100 or better clean environment.

as U wrote in the other thread, we can take a look at it in the EU, if needed.
