I have my custom built pc for over 4 years now but unfortunately, my hard drive is going bad with bad sectors, making the system freeze and restart for the past couple months. It's a seagate barracuda drive and i've used their drive tool as well as Windows bad sector and disk check and they only worked temporary as now it's not even starting up. How long is a hard drive to last because this is rubbish. I'm going to have to get a new one - what brand do you recommend and about how much I can get it for out here. I would like another 750gb drive.
