Hello,
thank you for the link, this is really interesting.
Here is a sound file of my hard drive with original PCB, maybe it will be easier for you to understand the matter?

Thank you again, i keep a little hope for datas...

The recording is too short to understand. 7-10 seconds long much better. But does not sound like stiction.
Rather, suspect it is a heads problem

I can't do much longer because it's the only sound i can hear. When i plug the HDD , i have this one second sound and nothing more. If i change the PCB (and Ic for sure), i hear 10 "beeps" and nothing more.
Thank you !

Ok, I believe it is a heads issue, or firmware on disk got scrambled. Starting to believe the latter is more likely, in which case there isn't much to do any longer.

Excuse me - a newbie - for sneaking in on this thread but I have exactly the same drive (5K1000-1000 HTS541010A9E680) and PCB (0A90351) but mine is actually spinning.
I tried it in my Lenovo laptop. I'll get "Error 2100: HDD0 initializing error (1)" during boot and no HDD is seen neither in SETUP nor in Windows/Linux.
The sound goes:
trt-trt-trt-trrrrrrt....trrrt...trt-trt-trt...trt-trt-trt-trrrrrrt....trrrt..trt-trt-trt...and then repeating. It's not loud, you must be very close to hear it.

This makes me think it's a mechanical (head) issue.

I have antoher drive, a 7K750-500 HTS727550A93E364 which looks very similar physically and have the same PCB (with another number, though: 0A90269)
I saw a Youtube video when they swapped the head on a simliar drive: https://www.youtube.com/watch?v=hKgYaFPb3c0

My question: is there a slightly chance that I can swap the head and also get it running?

Issues:
1) I don't think your donor drive is compatible
2) Need a proper cleanroom environment and head separation tools (unless you can build/improvise your own)
3) The drive worked on in the video is different than your drive from an architecture perspective. Your drive is much more trickier and difficult to work on, hence higher chance of screw up without experience
4) The tech in the video has very good technique. He spent hundreds of hours practicing, hence it looks "easy". As a result, most inexperienced people underestimate the difficulty in doing the work, jump right into it without practice, and screw up.

Agree, in addition it’s 99% certain that even if you are successful in fitting compatible heads there will be other issues such as media damage etc...

So in summary, this is not a viable DIY project. Sorry.

Thanks for your replies.

OK, I fully understand that this hardly is a DIY job but if you don't have anything to loose...so what?
A proper cleanroom would be nice, but you must agree that it would be an exiting project (with a very small chance of success, though).

Based on your experience: would you say that the sound indicates a head problem?
