Hello people! I would like to know if someone of you has this model of laptop! I need the specs of the hard drive for recovery issues. I know that it is WD2500BEVS but I need the date of manufacture and the firmware version if possible. I know that there is a sticker on the top of the drive but I peeled it off 

I am desperate! Ok,at least I know what kind of logic board I need, so, the problem is the firmware. Is it possible to upgrade or downgrade it from western digital ?
