Abstract
A headless computer entity has a license key data stored on a raw disk sector separate from a system disk and a data disk. The license key data control the available data storage capacity within the headless computer entity, and protect the computer entity from unauthorized upgrade to a higher product specification. The license key data are encrypted and protected from hacking via software updates introduced on an external data carrier, such as a CD ROM.
