I doubt that there is much you can do, but see this thread:

I'm not a data recovery professional, but ISTM that you could try to read the firmware MODs. That may or may not give a clue as to what is wrong.

Thanks guys for the advice

Yes i do have important data on it.

the main issue here is that we don't have recovery professional in our local market so what can I do ?

I found a tool from AFF laboratory called Repair Station

I tried the A-FF Repair Station but the result was :-











I am in-touch with A-FF team to see how they can come accross this issue.

I am traveling next month to BKK, I will try to contact the WD service center for data recovery, I will keep posting this post for you knowledge.
or if anyone can guide me for any further step

A-FF Repair Station makes some mighty claims but I haven't yet seen anyone report that it has worked for them.
