We just bought our desktop computer less than six months ago and today I got a warning message from Windows that I need to backup my file because the hard disk drive might fail. To make sure, I ran the Norton 360 Diagnostic Test and it confirmed that the hard disk will fail soon so I need to backup my files. I called the Geek Squad of Best Buy and advised me to bring the desktop to the store because it's hardware related problem and it's still under warranty. I don't have any idea why this happen. Anyways, I will be bringing this to the store the soonest.
