what are hard drives?
What does a hard drive do?
Storage is the hard drive’s responsibility. Everything you keep on your computer is on a hard drive. Not just documents, pictures, music and videos. Your programs, your preferences, even your operating system—they’re all stored on your computer’s hard drive.
If your hard drive is damaged, you can lose it all. That’s the sad truth. Which is why most people have a backup system. They get another hard drive and copy all their important files onto that.
