Huh? Whats a hard drive?
I’m going to start a monthly series of how or why certain things work the way they do, and I’ll do my best to make it understandable for everyone. If you have something you want to know about, please contact me, maybe I’ll do a blog post on it.
So whats a hard drive? It’s not where you go for a really long road trip (thanks for the jokes, dad…har har!) but it is easily mistaken for a bunch of other computer related stuff. It’s not the big glowy thing you look at on your desk (thats normally a monitor) and it’s not the big black box with all the wires hanging out of it (that’s your ‘tower’ generally, a.k.a computer).
A hard drive is a quick way of saying hard disk drive or HDD for short. It’s called that because it has actual, physical spinning disks inside of it. Those disks have heaps of little magnetic imprints that an arm swings back and forth on to read (like a super high tech record player). It’s the part inside your computer that stores all of your files.
Why does this all matter anyway? Well, because its physically moving, its sensitive to things like heat, or being moved while its turned-on (think laptops everyone!) and number one: it wears out. Sometimes, it will wear and you’ll lose little bits of information (think of that odd blip in a song that wasnt there before, or a photo all being an odd colour that you swear wasnt like that), sometimes important information that your computer needs. This can make it run really slow. If your computer is slower than normal, maybe you have a hard drive problem?
So what can you do about it? Well, number one: have a backup (I’ll probably do another blog on what a good backup is). Number two: if you’re looking at buying something like a laptop that you know will be moved around, get one with an SSD. These are smaller, but faster than a hard drive. What you’re really after though is that they have no moving parts, so they’ll be heaps more reliable for you.
So now you know what a hard drive is. Hope this helps!
