What is the difference between the FREE and Professional versions?

The FREE version provides basic data erasure functionality with limited capabilities. It supports only one-pass overwriting with zeros and is intended for simple data wiping tasks.

The Professional version includes all FREE version features plus advanced data erasure capabilities, including:

• support for multiple hard drives and simultaneous erasure operations;
• a choice of more than 20 data erasure standards, including NIST and DoD 5220.22-M compliant methods;
• additional professional features and configuration options for advanced users and business environments.
