Kako obrisati USERa na PS3 ?

Kako na polovnoj konzoli obrisati USERa, i njegove podatke o logovanju, a da mi ostanu DEMOi koji su skinuti sa PSNa? Da li je tako što izvodljivo? Dodao sam svoj USER, ali kada sam logovan na svoj, i "stojim" na njegovo, ne pojavljuje mi se da stisnem trougao i da obrišem .... a nisam našao ni u settings. Da li je takvo što uopšte moguće?
