thanks for all responses. now, i need to explain my friend why changing the pcb wont help and why he has to spend hundreds of dollars if he is to recover his data. can anyone tell where exactly the translator is and why changing pcb wont help?
Translator is the part of the SA on the platter.
It is a group of some modules, and one area of these is corrupt/unreadable.
If you choose one guru from the forum, you can ask the price in PM without shipping the drive.
This issue is not too much expensive, i think.

(In other way, -based on my personal experience-, if you send the drive to one little company "near to you" wich promise the stars from the sky to you, you will have 20-30% chance to get the data....)
