I have been given a Vaio PCG-Z1SP (though at the back it says, PCG-571M). But its hard disk (60Gb) is too small for me. I would like to upgrade it to a hard disk of at least 120Gb, but somewhere i remember reading that the kind of hard disk it uses is not a usual laptop IDE disk. Could someone enlighten me what type of hard disk it must have? I am tempted to try this, as I have a spare usual laptop IDE disk. What happens, if I put that in? Thank you.
