I read the whole thread with some interest as I worked in disk drive controller ASIC design team some years back.
Drives have very many auto calibration, detection and numerous smart features to greatly improve the reliability of writing data and trusting that it CAN be read back. When sector reads start to become suspect, the Defect Management System can copy data to reserved sectors and then map out the suspect ones.
I was suprised that most File System developers didn't have exact knowledge of this but were surmising it from limited experience.
I would hope that vendors would be forthcoming with even a cursary explaination if the FS developers asked, though not proprietry details.
