how to use galaxy ace as data storage with out installing drivers everytime

hi guys

this is manne again

i bought Galaxy ace in last week and im happy with its performances
but one problem im facing is i cannot go and plug in to any system i require as it is asking administrator to install drivers. previously i use Nokia c6 and have this kind of problem. when i give data storage option in that it just works fine as a pen drive. please tell me if there is a way so that i can use my ace lice that
