Hi everyone, just brought my tivo today from jb hifi but as of yet havnt connected it cos i dont have a long enough ethernet cable (getting it tomorrow) but im going to upgrade my hdd pretty much straight away soo im thinking either 320gb or 500gb

so my question's are

1) what physical size is the tivo hdd is it 3.5' or 2.5'

2) is it sata or ide

3) what exactly do i have to do? do i just swap the hdd and powerup? or do i have to update something? do i need to get a certain drive? pretty much is there anything special i need to do to install a new HDD?

cheers, and thanks in advance
