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 Single 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: P A 240MB hard disk can store as much data as approximately 198 1.2MB diskettes or 165 1.44MB diskettes. P Your computer can perform all disk-related operations faster. 0 You can store frequently used programs and data files[...]

Backing 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 back the[...]

Changing the Processor Speed Your computer’s processor can operate at two speeds: high or low. High speed is the highest speed at which your microprocessor is capable of running, such as 33 MHz. Low speed simulates an 8 MHz processor to provide compatibility with older application programs. You can also set the computer to automatic speed which s[...]

Some copy-protected programs require the computer to run at low speed while accessing the program on a diskette. These programs also usually require you to leave a key disk-the diskette that contains the copy protection-in the diskette drive. If you use a copy-protected program often, you may want to set your processor speed to change automatically[...]

If you frequently use programs that require low or automatic speed, use SETUP to change the processor speed. Your new setting remains in effect until you change it again using SETUP. See Chapter 2 of the Setup Guide for instructions. If you use these programs only occasionally, you should use the keyboard commands or the ESPEED program (described b[...]

Note You can use the commands listed above while you are running a program. However, if the program uses one of these commands for another function, you cannot use it to change the processor speed. For example, if you are running a program that uses the [cbll[m - command to move 6 the cursor, you cannot enter [mJIm1[-1 to change the processor speed[...]
