All thats needed to wipe the disk is to delete
You are jumping to a point in time after what I am asking:
“all you need” is to delete a key -> No, you need to encrypt the disk before, which is the step prior, and without it, deleting a key change a thing…
So basically, the part “hardware” built-in could make sense, but the guy didn’t specify any if this…
In other words, zeroing the disk is going to be faster “in normal circumstances”.


The whole problem and why people are zeroing is that “empty space” is not really empty.
