Security Hardware
KillDisk authorization is provided by an external or internal removable USB dongle containing a license and user information. The USB key must be inserted all the time, otherwise software authorization error pops up.
Note:
Security USB dongle is NOT a regular USB Flash Disk, this is specially designed hardware token for the software authentication. It cannot easily be replaced if lost or damaged. Please keep it safe, otherwise you need to pay a full price for the license replacement.
