Lost data !!!!

[Debugger]

Bios can not see the disk WD 3TB, the system also.
The disk is working (discs are spinning)
For a moment (a few seconds only System detected that the partitions were damaged).
It does not work now, Hard Disk Sentinel has previously detected about 58 defective sectors.
I really care about recovering valuable data, but repair can cost a lot 1000 PLN (~300 USD !!!!!)
I do not know if it is possible to repair the disk itself, eg, turn the mechanism so that the heads return to parking, I saw it on YouTube, some help it, but I'm afraid that opening the disc may be associated with new damage, I heard that dust particles are settling on the plates can cause further damage, and it is not recommended for amateurs only for professionals.

I think it's nice that some forum participants repeatedly answer such and similar questions.
In my opinion, this question does not belong in this forum.

Sorry to hear you for data loss.

I am in no way a hard drive repair specialist and I would recommend you see one..

You may like to try:

• Try a different sata cable
• Try a different sata port
• Leave the hard drive powered on for a while as it might be in recovery mode and relocating bad sectors.

The disk works (discs spin) but you can not hear the disk head working. Disc not detected in any case. I am afraid that the problem with the disc heads, although I am not an expert in this field.
This is the biggest nightmare in my life.
