This is really not that big of a problem His point is that traditional hdd wiping techniques don’t work because they were designed with magnetic plates in mind. To make this a big deal claiming it is a flaw in SSDs is like trying to claim that a nail is flawed because a power drill won’t drive it into a block of wood when you try to drill the nail. You’re simply using the wrong tool so of course it’s not going to work. I’m sure doing it a few times might be required.”]
