Hi R.S., I enjoy your sense of curiosity. The customer security document I referred to earlier said that there are commercial products available that can erase up to 99 times. It did not express concern about this limitation of capability, or suggest erasing 99 times and then another 99. So I would infer that 100 times is considered certainly *more* than enough. Sorry this probably doesn't satisfy your desire for justification; sometimes when my son asks me Why? (every few seconds) I can't or don't answer either.
