On a hard drive, heads on moveable arms impart magnetic charges to sections of spinning discs. In effect, these charged sections are the files you bring up on your computer. And, while your merry-go-round spins at a nice leisurely pace, the discs that hold your info, also known as platters, are whirling around at speeds up to 15,000rpm. When you realize that one tiny particle of dust or dirt in your drive can ruin the drive, it’s amazing we don’t have more trouble with this vital component of our computers.
Hard drives are temperamental about the temperature inside your computer’s case. Cleaning the inside of your case is a surefire to keep your drive cool. All you need to do is remove one side panel on your case and use a can of compressed air to blow the dust out of your computer. Most cases have a couple of screws or thumbscrews screwed into the back of the case.
Before you dive into dusting your computer components, touch a piece of metal to get rid of any static electricity that may have built up. Though it may literally be a shocking experience for you, it will be much less painful than having to replace a fried hard drive or motherboard. Another option is to buy an inexpensive antistatic wrist strap, which keeps you static-free while you work inside the computer.
This is also the perfect time to check your fans to make sure they’re all working correctly. You must have properly functioning fans to ensure that air can circulate through your case. Once you’ve cleaned out your case, make sure cables are clear of fans, and turn on your computer while the side panel is still off.
External hard drives also need some special attention. If you use one, make sure it has space to do its thing. These drives can overheat just like internal drives, especially if they’re surrounded by books, stacks of papers, and other such material. An external drive needs to be able to circulate air in order to keep cool and this can’t be done effectively if the drive is cramped for space.
