I have collected some information about shock sensors, particularly those made by Murata.

2.5" platters are made of glass, deformation is highly unlikely, even if some "potato chip" effect can be observed, it's probably minimal and can be ignored

the WD model you have has special servo-to-data position calculation that depends greatly on original bearing being intact, which is often not the case on old or even dropped drives.
Very possible that vibrations you applying move disks packet inside the bearing just enough to bypass the read errors. Keep in mind that vibrations could cause heads to come near or even touch the surface, which is not a good thing.

Thank you for this clarification I had not thought about this detail.

I think they are usually made of aluminum, and there were a number of HDDs that were made of glass and that had more drawbacks than advantages.

I totally agree, right now what I'm doing is very risky, I've only used it 3 times and when I did not know another way to read the sectors that I had left. In the last I spend a little and stick heads to the dishes.

I would be really surprised if you can find 2.5" drive with aluminum platters

Thanks for the clarification and sorry for my confusion.
You're absolutely right I just checked with 3 HDDs and all three of glass.

I don't know how accurate it is, but SA module C5h contains DCM information, including heads, media and preamp vendors and part numbers.

Very good work

When this problem happens again, I will try to change the dishes to another HDD, to see if it reads those sectors without problems and the deformation of the dishes could be discarded.
Thanks again for the indication.

It seems that I am again faced with an HDD that may be that the bad sectors are read with vibrations (I'm not sure, at the moment I'm taking out the information).
I put a picture of the vibrators that I got to perform the test. They are stuck only by the front to the HDD.

@mph666, what were the vibrators removed from or from what were the constructed?

I bought them on Aliexpress.

I hope to be able to do a test with the HDD that I am recovering, because it has all the looks to be a candidate.

Thanks. Good luck with your experiment!

I just tested the vibrations in a HDD WD10JMVW and they do not help me to finish reading the approximately 64k sectors that it reads with errors.
Any ideas to try to recover these sectors?

_________________

If in the last 2 cases I had, if I managed to recover the data 100%. In one of them I think I remember that there were about 2400 sectors and I read them in less than 1 minute.
In this case where I am I can not recover a single sector, I will wait for an HDD to come out with these conditions and I will try to draw conclusions.

Greetings.

I do not remember the HDD models (badly done by me).
But I think it happened to me with wd and toshiba.
