Chapter 9. Hard Drives and Floppy Drives
Many people use magnets to stick little notes onto their refrigerator doors. Your PC also uses magnets to store your information, but with a slightly different approach. Every time you save a file, your PC transforms your data into little magnetic codes, and then spits the magnetic charges onto flat platters that whirl more than 5,000 times every minute. Even more miraculously, your computer's able to retrieve these codes on demand and turn them back into your words, pictures, and songs.
This chapterand the two that followdon't even try to explain how any of that happens. But these chapters do explain how to find all the drives connected to your PC, keep them running smoothly, clean them up when they get too full, and add new ones when you just plain need more space.
