- Write fingerprint
This feature will write the specified fingerprint to the first sector of the
erased drive. If a machine is booted from this drive, the user will see this
fingerprint as a message on the screen.
- Erase confirmation
As a safety precaution to prevent accidental destruction of hard drives,
KillDisk has the user type a keyphrase before the erase procedure is
initiated (Figure 3.1.6). By default this precaution is set with the
keyphrase "ERASE-ALL-DATA". This keyphrase can be modified, set as a
randomly generated set of characters, or disabled in these settings.
