What is Disk Fragmentation on Windows and how does it optimize your hard disk?
In: 57
Your hard drive is a disk. Imagine all of the area on the bottom side of the disk is memory. When you ‘burn’ the disk, you ‘burn’ the files onto it, so that your CD-ROM can later read it. Imagine burning a few large files that take up a lot of area. Now you’ve got spare space scattered all around the disk. A tiny piece of free area (memory) here, a little bit there. After the leftover space is split accross the disk, when you’re burning something else on it, you have to use the leftover empty spaces that are all around the disk. This makes it harder to access those files – the disk has to rotate more times for the laser to pick up the bits of files. Defragmentation takes the scattered pieces of files and brings them as close together as possible, so your disk has to rotate less to access files.
