PCB : 100574451 REV B

I have 3 hd of this model and in principle with the same symptom. it hits the head and the engine stops.

It does not give me output per terminal. I have another with another plate model and if it gives me output per terminal.

I could try loading the virtualloader and the loader but I can not find them.

Any ideas. Thank you.

Thanks for the reply.
This is a seagate firmware update.
Can I get the ldr that the mrtlab uses from it?

Check PCB first

I've thought about it because it does not give a terminal and the engine speeds up a lot.
I have another 2 more broken with the same symptom in principle.
Do you know if the breakage of the PCB is typical of this model?

Here is the tool:

Cut off the excess, everything that you think is not necessary. It also can send loader by ATA.

If the PCB will be good the heads neads to be replaced. Typical is bad word in data recovery. I always check simplest solution at start.

Thank you very much for your interest.
I had never seen the LodEdit, I am going to study it and try it and I will comment on the final result (good or bad).

I give up the case.
The three disc has the same symptom, the engine accelerates more than the account, the problem; I put the photo.

The four surfaces are scratched.

Anyway, I'm going to see the theme of this plate model that does not give me a terminal when it's isolated. I will speak with MRTLAB.

If I take something out of the terminal with this model plate I mention it.

Thank you.

With these Seagates, it pays to listen to them before spending much time on them. If you hear scraping noises, they usually have platters that look like yours. Rather than open the drive in a cleanroom environment, I remove just one of the screws that secure the magnets and if it's covered in data dust, it's obviously a goner and would make a hell of a mess of your laminar flow bench.

I'll remember that for next time.
I miss the noise that made, it seemed that the engine was faster than normal, but it seems that the noise was due to friction.
