BCWipe allows wiping data using predefined wiping schemes: one random pass, DoD 5200.28-STD and Peter Gutmann. Additionally, the software includes the Wiping Scheme Editor utility to view and edit number of wiping passes and binary patterns used in every pass. Using Wiping Scheme Editor you can customize all the details concerning wiping process on your computer.
