"In this Beginners Guide, we'll cover all the necessary steps for installing and preparing a second hard disk drive on both Win9x/ME and Win2K/XP systems, as well as setting up the hard drive for installation on a brand new computer with no operating system. As both IDE and Serial ATA hard drives are used in modern PCs, we'll also investigate the differences between these two types of hard disk. Fortunately, hard disk space continues to expand affordably. As the average computer can use up to three hard disks in addition to a CD drive, it's easy enough to go out and buy a new drive to add extra storage space to your system."
