I'm testing it continuously with this 2.0 TB WD, and I'm sure it's because of the vibrations. I come as soon as I stop giving vibrations stop reading well and leave many sectors unread and if I give it vibrations it reads it almost 100% and what it does not read in the next pass reads it to me if I give it vibrations.

From a technological design perspective, the "tapping technique" does not make much sense in theory.
If this method was perceived to have worked on a Toshiba laptop HDD, which I vaguely believe you may have posted about on the forum somewhat recently, it worked more than likely because the bad sectors have "become healthy, therefore readable" due to an "inner ECC method" existent on some Toshiba drives.
I remember the case you told me and that thanks to the vibrations I made an exact copy of the HDD.
Or it is because of the eccentricity or it could be that the heads take with the vibrations an optimal distance to the plate. For the moment I am leaning towards eccentricity.
Until I discover another method to gain access to these sectors that I can not read, I will continue using this method, although I do not like anything.
