Yeah, a lot of BIOSs do a "SECURITY FREEZE" command before booting, which disables things like "SECURITY ERASE" until the next hard reset.
So, on a Linux system, just unplug the drive after booting, replug it, and usually it can then be erased.
But yeah.. that all makes things tricker for non-techies.
