when i delete items of my psp the memory i deleted doesnt come back it stays the number it was?! and to get the memory back i have to reformat. Ex. i have 45mb left on my memory stick and i put a song thats 5mb now its 40mb left, now i just delete the song that was 5mb the memory should be back to 45mb. but not on mine for some reason it would stay on 40mb. and the only way is formating the memory stick. i need help please try to give step by step help or any suggestions. iv tried it with different memory sticks so its not the memory stick. by the way my memory stick is fake but iv used it for a year and the problem just coused a day ago wheni did something but dont know what.
