How Disks Store Data Diskettes are made of flexible plastic coated with magnetic material. This plastic is enclosed in a square jacket that is either slightly flexible (5.25-inch diskette) or hard (3.5-inch diskette). Unlike a diskette, a hard disk is rigid and fixed in place. It is sealed in a protective case to keep it free of dust and dirt. A ha[...]

Double-sided, double-density diskettes have either 40 or 80 tracks on each side, and double-sided, high-density diskettes have 80 tracks on each side. Diskettes can have 8,9,15, or 18 sectors per track. A hard disk consists of two or more platters stacked on top of one another and thus has four or more sides. In addition, a hard disk has many more [...]

Using a Sing/e Diskette Drive System Most operating systems expect the computer to have at least two diskette drives and display prompts and messages accordingly. MS-DOS, for example, recognizes the first diskette drive (the top drive) as drive A and a second diskette drive as drive B. If you have only one diskette drive, MS-DOS can treat it as bot[...]

Formatting Diskettes Before you can store data on a new diskette, you must format it. Formatting prepares the diskette so that the operating system can write data on it. You need to do this only once, before you use the diskette for the first time. You can also reformat previously used diskettes to store new data. This process erases all the data o[...]

Using a Hard Disk Drive Using a hard disk is similar to using a diskette. However, the hard disk provides several advantages: tl A 120MB hard disk can store as much data as approximately one hundred 1.2MB diskettes or eighty-three 1.44MB diskettes, and a 240MB hard disk can store twice that amount. CI Your computer can perform all disk-related oper[...]

Bucking up the hard disk While the hard disk is very reliable, it is essential to back up your hard disk files to diskettes or tapes in case you lose some data accidentally. Make copies of all your system and application program diskettes before copying the programs to the hard disk. After you create data files on the hard disk, be sure to copy the[...]
