Seriously, the repair can most likely be made via Terminal, but what I am trying to stress is that there are so many variations of similar commands and the risks associated with entering wrong command is very severe.

Most likely the issue you have is translation system needs to be rebuilt, but without real diagnosis from a professional it is practically impossible to confirm this. There are many commands related to rebuilding translator, some posted at this forum previously, but some will end in "SMART FAIL" error, others will simply not work and in the event of it being successful there is a huge probability of limited LBA access.

This is assuming the problem is not elsewhere, which also is a possibility...

100% agree with you here

thats why i did not want to continue with comments which might be used WRONG and disasters happen after.

seek a pro.
& good luck

When FREE INTERNET SOLUTION don't work, there is no alternative to know-how. Unfortunately there's a price tag on it.

P.S. "HD DOCTOR" and other more expensive tools don't have a "REPAIR IT FOR ME, STUPID ! " button - you must figure out what's the problem and then correct it (most of the times via terminal or correcting firmware modules if they are proven to be corrupted).
This is one of the case where there is a 70-80% possibility of garbling adata applying random "I-found-it-on-the-internet" solutions and there is NO diagnose.
Who dares wins (for free) but the outcome may be unpredictable / infaust ... your data (or whoever data is) , your choice.

ok undestood.
In terminal can i give some commands just to have a diagnostic about the problem? Or i will need hd doctor or similar for the diagnosis?
If you tell me some commands for the dignostic in terminal (not for fix it) i will show you the log, so you pro can understand what's the issue with the drive.
What do you think about my idea?

Also, how much doest it cost to make fix this drive to a pro?

I guess even having tools like SD or Acelabs, 80% work is done using diagnostic commands.
So do research, lot of (while fragmented) information is available, also on this forum. Then come back, so people can see you actually did some work, they know don't waste their time, they will help more.
I think you received some important information already in this thread, not enough, just a base for further investigation.
A comment like this is a sign that you are asking too much:

a comment like this SIGN means: thats why i did not want to continue with comments which might be used WRONG and disasters happen after.

My uncle want to sent the drive to a professional laboratory (the drive is his).
Thank you for your time.

Actually it can be seen better from a distance. When einstein9 talks about disasters, it means it gets bored...

Blah... Blah....Blah.....

subject close... and good luck Basco..
