After a lot of consideration, I actually decided to order myself a new, 320GB, HDD for my PS3. With my history of needing to replace my PS3, my main worry is what would happen to my HDD if my console broke down. But I decided that it should be okay, so decided to go ahead with it anyway. It also helped that I had £20 worth of Nectar points to spend, meaning that the HDD was basically half price when buying it with a £20 Amazon Gift Certificate. So I should get it in 5 days or so. My only worry now is installing it, since it's been said that the PS3s screws for the HDD are really easy to strip. I might get my dad to do it for me. Lets hope we have to right screwdriver.
