Cannot detect my network drive at all ... its my book world edition

hey i got my drive kinda mapped . Wd discovery still doesnt recognise it though. I have the white light 2tb my book world edition . Using xp sp3 . A cisco EPC2425 router . Xbox even picks it up . Put some files on it when i mapped it , not sure if there safe though . Have contacted WD support they were rubbish told me its definitely my anti virus which i disabled . And then firewall . but nothing im at a serious dead end . Already pulled my hair out .
