I well remember one utility provided by DEC, a mainstream company at the
time, that reported "Completed -OK". But had, in fact, not over-written
a single byte.
Plus very many other promises of functionality by software houses, that
haven't proven to be justified.
Since then I haven't trusted any software that I haven't written myself,
in assembler..
So the "two different secure erase methods" wasn't because one wouldn't
do, it was lack of trust of other people's software. With any luck, they
both won't fail - at least won't both fail in the same way and without
warnings.
