I have a computer that's been running not too well lately. I took it to Staples and after keeping it over night they said my hard drive is failing and I need a new one. I ran disk check, hard drive checks out fine. I ran Space Monger and it was able to index my entire hard drive successfully. The PC still boots and runs (although it freezes sometimes if it's not in safe mode).
Their diagnosis just sounded off to me and they couldn't really elaborate past "The hard drive is failing." Could they be correct and how could I double check this?
