If that were true, we'd have infinite storage capacity.
- taeric 5y agoGiving some charity to the claim, I'm assuming it meant on devices you plan to dispose of.
- neolog 5y agoI don't see how throwing it away improves storage capacity in a way that would invalidate GP's comment
- taeric 5y agoThe assumption isn't infinite capacity. It is recovery of the last data.
- DSMan195276 5y agoIs that fundamentally different from the question of whether overwriting data can make it unreadable? If yes then you can eventually make the "last data" unrecoverable by overwriting it. And if no then presumably you can recover anything previously written to the disk, ergo infinite capacity.
- tempestn 5y agoPresumably the original comment meant that you can't guarantee the original data is unreadable with any finite number of overwrites, not that you can always read the original data after overwriting. I'm not saying that's true, but it's a logical interpretation that doesn't imply infinite storage.
