Cenois

Hi my bro manually formated my NW-E505, he deleted all the files on it (OMGADUIO is still there, but i think its missing a few things). When ever i turn it on it says Data Access and then Format Error. Also when i hook it up to sonic stage 4.0 cp i am able to get into the device/media info but the properties no longer appears the reset button also gives me the same message so i was wondering if an1s got any ideas on how i can get it to work again or if they have the original files for the NW-E505 could you please send it to me. thx
