i have a 3yr old laptop (dell i8600, still on the original xp install!) that still has the original hdd. as far as i can tell everything is fine with the hdd, but considering the beating this thing has taken and the amount of hours ive put on it, i kind of wonder about its health. Are there any programs/diagnostics i can run? I've heard spinrite is a good program for preventive maint., can anyone comment?
