    You take your sdcard and Hulk smash it? Just joking. Did you tried opening a file and filing it with random numbers and saving it. Do this several times and it must be gone :) – Marko Lazić Jun 05 '13 at 11:20

    "beyond recovery", maybe not... But you can open it, write random stuff into it, close it and then delete it. – fge Jun 05 '13 at 11:21
