BCWipe performs 7 passes of wiping when it shreds information according to the scheme. 11 passes means that BCWipe overwrites the information 7 times, and uses different byte patterns for overwriting. For example, in the first and the last (7-th) passes BCWipe uses random bytes to overwrite data.

Then set
Random radio button - if you wish to use random bytes for overwriting;
Complementary - if you wish to use byte pattern complementary to the previous pass;
Cycled byte patterns - if you wish to set a concrete byte patterns for the wiping pass;

To insert additional pass to the scheme, click Add.

To update existing pass, select the pass in the list of passes and click Update.

To remove a pass from the wiping scheme, select the pass in the list of passes and click Remove.
