I recently read a How-To Geek article that talked about checking your drives for any problem, so I downloaded CrystalDiskInfo and it told me "Caution". Like you see in the pic, the "Reallocated Sectors Count" is at 100, and the threshold is 36.
Also note that my hard drive makes a sound sometimes. I couldn't describe it so I recorded 10 seconds of it and uploaded it here
What should I do?
I would appreciate any help.
