m not sure what size hdd it supports but i would go for the biggest i could afford probally
they state size dosent matter its the way you use it but i have found it does help to have a big one!!!
not sure what the biggest 2,5 hdd is at present the largest ive seen is 160gb
its ide interface aswell which is becoming old technology now as most laptops now have sata drives installed into them which may be a good thing for us
as the prices on old ide drives may start to plumet
but if there is a huge demand for them they may start to rise again
think we should all start looking for good deals on hdd aswell
