Enforce initialization

Only when the SD is new, I get the dialog to allow a complete erasure of that SD card inside the NK Storage. Is there a way how I can enforce this ? So that I could secure delete all data ?
:smiley: [Update] I used “sudo /Application…/…/…/nitro-app.app --admin”, which is opening a special menu to init the SD Card with random numbers again.

Question marked as solved.
