I think wiping the disk using factory reset isn’t going to wipe or overwrite the data though, especially on SSDs. If you try to overwrite files or sectors, that may not actually overwrite those specific sectors either. All unencrypted data may be available to read.
My guess is you’re out of luck if you don’t trust full disk encryption when it’s done right from the beginning of using the machine. Physical destruction isn’t cost effective when the machine is sent for repair.
- jonnycomputer 4y agoIs it possible to securely wipe a SSD? Or better to encrypt whole drive, throw away the key, and maybe corrupt a few random bits?
- AnonC 4y agoYes,that’s certainly possible with the response that bitwize provided in a reply to your comment. But the GP doesn’t trust full disk encryption or the firmware. For such people, there is no way other than complete physical destruction.
- bitwize 4y agoThere is a "Secure Erase" command in the ATA command set that pretty much does just this. Modern SSDs have firmware-level encryption with a hidden key only the firmware knows; Secure Erase simply obliterates and regenerates the key.
