You know that you can't truly "wipe" SSDs, right?

• detaro 8y ago
  It's not that simple. A secure erase should wipe all blocks (and since it is done by the firmware, physical blocks, not logical ones), but there have been instances of buggy drives that don't actually do it properly. Some SSDs also transparently encrypt all data written, and the key is replaced on a wipe command. Even if they don't wipe the data fully, it's now unusable, if the encryption works correctly. Quite old SSDs might not support any of this.

    I thought all SSDs support ATA password.

      I don't think ATA password necessarily means the drive content is encrypted, or helps you fully wipe a drive you obtained from somewhere else.
