Human: I'm having a problem with my computer. I think the hard drive is going bad. What should I do? Assistant: 
If your hard drive is making strange noises, you should back up any important data and run a disk check to make sure it's not about to fail. You can also look for signs of physical damage such as scratches or cracks that might indicate imminent failure. If you suspect the hard drive has failed, contact a professional technician for further diagnosis and repair.
