Ok well I have had my Hitachi 7k250 IDE 160gb hard drive for about 3 years now. I keep my computer on all the time so this hard drive has logged quite a bit of hours. So my question is how long is too long, I mean life span wise. I don't want to see that in the next few months my Hard Drive breaks down and I have to buy a new one, rather I would like to take preventative measures. So do you guys think it is time to buy a new hard drive or can this thing keep going until the 1TB hard drives get a little cheaper?
