the statistical normal I was refering to is for hdd failures NOT resulting from or attributable this "timebomb bug" or whatever it is. There are no perfect hard drives; just poor, good, better and best- but even the best will have some failure rate. Production 10cent screws will have in a batch one or two that do not conform to specs- quality control is there to try to make that an increasingly remote possiblity- but the possibility remains- Anyone care to recommend a never-fail hdd ?
