You will need to first set up the drive you want Eraser to overwrite, and then to choose the way it will do it. Establish a task
Click on File.
Choose New Task.
You will see a drop down labelled Task Properties with a Data tab.
Check "Unused space on drive" and choose the drive to be overwritten.
You will see your choice entered into the On Demand task list. Check to make sure you are doing the correct drive.Choose the Method
Next, click on Edit, then on preferences, then on Erasing. You can choose different
methods for a simple erase of current files and for unused space overwriting. I generally use the option of 3 passes for current files and a single pass for unused disk space (especially since I use Eraser instead of deletion).
You are given the choice about how Eraser will overwrite in both cases, from the Gutman algorithm (35 passes) to a simple pseudorandom single overwrite. Since you do not have sensitive data on your computer, you can choose the single pass for speed for the unused space, and something more powerful for your on-going use. Click on OK.Run the task
When you have chosen the options, go to the On Demand task list, right click on the line for the desired task in the list and choose Run. WARNING!
Double check everything; Eraser is a powerful application and its erasing cannot be reversed or undone.
Hope this helps,
