Yet if you ask how to wipe a disk on a forum, you'll get user-space ideas like `dd` and `shred` :(
- techdragon 13y agoA lot of people want a more physically certain level of data destruction than such a command provides. If I saw that a drive wrote 3-5 passed of junk data before zeroing the disk then I would trust it but such firmware level info is rare to impossible up find.
- phamilton 13y agoMany SSDs do on the fly AES encryption. Secure wipe is then just a destruction of the private key. All the encrypted data stays put.
- venomsnake 13y agoSince when there is private key in AES? And that requires a paranoid person to trust that a company does not holds the keys in escrows somewhere or are by any way retrievable.
