4 SCSI and IDE Hard Drives and Optical Drives Chapter 4 Understanding Hard Disk Terminology When installing IDE hard disks in particular, at least three parameters must be indicated in the BIOS Setup program to define a hard disk. Note Understanding how hard drives store data is an enormous topic. If you’d like to learn more, see Chapters 9 and 10 of Upgrading and Repairing <strong>PCs</strong>, 12th Edition, also published by Que. Heads, Sectors per Track, and Cylinders If this information is not accurately listed in the BIOS configuration, the full capacity of the drive will not be available unless special hard disk drivers or supplementary BIOS cards are used. Whenever possible, the computer’s own ROM BIOS should fully support the drive’s capacity. For drives larger than 504MB (binary) or 528 million bytes, additional translation options are also required with MS-DOS and Windows to achieve full capacity. Hard Drive Heads A hard drive is comprised of one or more platters, normally made of aluminum but occasionally made of glass. These platters are covered with a thin rigid film of magnetized material. The magnetic structures of the platters are read or changed by read/write heads that move across the surface of the platters but are separated from it by a thin cushion of air. Virtually all platters are read from both sides. Sectors per Track The magnetic structures stored on the hard disk platters are organized into sectors of 512 data bytes each, plus additional areas in
