that's a problem.. u need to reconfirm back with your brother.. maybe he just wanna use it as an external hdd.. why bother buyer here if he can get it cheaper oversea..

vista.. some of driver really troublesome cause need to search manually and some dint ever exist for vista.. you can buy it then take it to any pc shop(better if they can install for you.. only rm30 the ehem version lor).. as for my boss shop.. we reinstall back acer laptop (celeron m) with xp cause so heavy and laggy if use vista.. need to get the driver on the net.. some of vista driver can use on xp(backward compatible)..
