Eraser comes with the ability for you to create your own erasure methods for file overwriting. This is accomplished by right-clicking the Default Erasure Methods and PRNGs plugin in the Settings page, then selecting Custom Erasure Methods. You will be presented with the Custom Erasure Method Editor. Custom Erasure Methods

Provide a Name for the erasure method, as that is how you will identify it in the list of methods, then add any arbitrary number of passes.

  • Randomize pass order will cause the passes to be jumbled every time the erasure is run.
  • Add, Remove, Duplicate, Move Up, Move Down will operate on the currently selected pass in the pass list
  • Pass Data allows you to specify the data for the pass:
    • Text/Hexadecimal will be for your own data. Text will be treated as normal input (UTF-8) and hexadecimal will be used for raw data. The data will be repeated for all parts of the file/unused space until erasure is complete. The interconversion between Hexadecimal and Text may not be lossless (especially if the hexadecimal number translates to a non-Unicode codepoint)
    • Random will erase the file/unused space with random data
