The enemies of disk drives are dust, heat, impacts, liquid, voltage spikes, and Windows (I might be kidding about Windows).
Don’t use your computer in the bathtub. Don’t use your computer around happy hour.
Don’t drop your computer! Don’t drop your disk drive.
Voltage spikes.
It’s actually high voltage and can damage your computer, especially if you have opened up the box ; touched something inside.
Heat is public enemy number one for computers. Heat kills computers and disk drives. Disk drives generate heat and many people stack several disk drives together in their computer with no space between. If it’s uncomfortably warm for you, it may also be so for your computer.
Dust
Heat and dust walk hand in hand to damage your computer.
Change the computer’s location.
Dust out your computer every three months or so. You’ll want to use clean compressed air – canned air works great, but if using an air compressor, make sure the air coming out is clean and dry by blowing it at a piece of white notebook paper first.
You will want to have the computer unplugged. If possible, you’ll want to have the computer’s case open (unless it is a laptop). Blow out the space between the hard drives.
