Is the "EEPROM calibration information" enough? Can you even obtain that?

My understanding is that without specialized calibration equipment,
transplanting platters in a multi-platter drive is a futile effort, as
the platters have to be precisely aligned to replicate how they were in
the original drive when the servo tracks were written.

With a single platter drive, a transplant might be possible, but there
may be other interplay between the calibration settings stored in the
drive's EEPROM. I'm guessing that's what Nuno is referring to.

Once upon a time, this trick worked. Not so much with modern drives.
