The HDD in one of the laptops had died... It was a Hitachi 5K500 - But the 400GB model.
I have found this one to buy... It is the exact same model as far as I can see... But in the 500GB version. So will this HDD work? All I will need to do is load windows onto it and chuck it back into the laptop...?
Also... If anyone else has any better suggestions about an HDD it would be really appreciated as ive only had a short look around.
Just wanted to check before I bought it...
