Page 77: Using Disks And Disk Drives

Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use your stored data when you want to. Your computer comes with a single diskette drive or one diskette drive and one hard disk drive.
Page 78

All disks are divided into data storage compartments by sides, tracks, and sectors. Double-sided diskettes store data on both sides. On each side, there are concentric rings, called tracks, on which a disk can store data. A disk is further divided by sectors. To understand what a sector is, picture the spokes on a bicycle wheel radiating from the hub of the wheel to the tire.
Page 79: Types Of Diskette Drives

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 tracks per side than a diskette, but the number of tracks depends on the capacity of the hard disk. The number of sectors depends on the type of hard disk.
Page 80

Ll 1.44MB drive-with this drive, use 3 ‘/z-inch, double-sided, high-density, 135 TPI, 1.44MB diskettes. These diskettes contain 80 tracks per side, 18 sectors per track, and hold up to 1.44MB of information, which is approximately 600 pages of text. CI 360KB drive-With this drive, use 5 ‘/+inch, double-sided, double-density, 48 TPI, 360KB diskettes.

Page 82: Caring For Diskettes And Diskette Drives

Caring for Diskettes and Diskette Drives Follow these basic precautions to protect your diskettes and avoid losing data: If you have a diskette that contains data you don’t want to accidentally write over or erase, be sure you write-protect it. This is especially important for your operating system and application program diskettes.
Page 83: Write-protecting Diskettes

The surface of a 5 ‘/r-inch diskette is exposed by the read/write slot. Always hold the diskette by its protective jacket and never touch the magnetic surface. The oils on your fingertips can damage it. Do not place anything on top of your diskettes, and be sure they do not get bent.
Page 84

To write-protect a 5 ‘/+inch diskette, cover the small, rectangular notch (shown below) with an adhesive write- protect tab. Write-protect tabs usually are included in a new package of blank 5 %-inch diskettes. kite-protect notch To remove the write protection, peel off the write-protect tab. Note MS-DOS diskettes Some program diskettes, such as your...
Page 85: Using A Single Diskette Drive System

On a 3 ‘/z-inch diskette, the write-protect device is a small switch on the back of the diskette in the lower right comer, shown below. To write-protect a 3 ½-inch diskette, slide the switch toward the edge of the diskette until it clicks into position, exposing a hole in the comer.
Page 86

For example, if you enter a command to copy data from A to B, MS-DOS copies the data from the first diskette you place in the drive (which would be drive A) to the computer’s memory. Then MS-DOS prompts you to insert another diskette (for drive B) and copies the data from memory to the new diskette.
Page 87: Inserting And Removing Diskettes

Inserting and Removing Diskettes If you have a 5 +-inch diskette drive, insert a diskette as follows: hold the diskette with the label facing up and the read/write slot leading into the drive, as shown below. Slide the diskette into the slot until it is in all the way. Then turn the latch down to lock it in a vertical position.
Page 88: Formatting Diskettes

To remove the diskette, press the release button. When the diskette pops out, remove it and store it properly. Caution Never remove a diskette or reset or turn off the computer while the diskette Also, be sure to remove all diskettes before you turn off the computer.
Page 89: Making Backup Copies

Making Backup Copies It is important to make copies of all your data and system diskettes. Make backup (or working) copies of all diskettes that contain programs, such as the original Reference, MS-DOS, and Utility diskettes that came with your computer, and use only the copies.
Page 90: Using A Hard Disk Drive

Note Using a Hard Disk Drive Using a hard disk is similar to using a diskette. However, the hard disk provides several advantages: A 40MB hard disk can store as much data as approximately thirty-three 1.2MB diskettes, and a 100MB hard disk can store as much data as approximately eighty-two 1.2MB diskettes.
Page 91

Backing up the hard disk While the hard disk is very reliable, it is essential to back up your hard disk files to diskettes 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 them to diskettes whenever you revise them to keep your backup diskettes up-to-date.
Page 92

Follow these steps to run HDSIT: Exit any program you are using and make sure the MS-DOS command prompt appears on the screen. 2. Insert the Reference diskette in drive A. 3. Type the following and press A:HDSIT You see a message on the screen that tells you the disk drive’s read/write heads will remain locked until you reset the computer or turn the power off and on again.
Page 93: Enhancing System Operations

Chapter 4 Enhancing System Operations This chapter tells you how to take advantage of the following enhancement features of your computer system: tl Using AUTOEXEC.BAT and other batch files 0 Changing the processor speed CI Reassigning the diskette drives CI Using your computer as a network server Ll Using expanded memory beyond 640KB 0 Using special VGA features.
Page 94: Changing The Processor Speed

A particularly useful batch file you may want to use is called AUTOEXEC.BAT. Every time you turn on your computer, MS-DOS looks for the AUTOEXEC.BAT file and automatically executes each of the commands. When you install MS-DOS, it automatically creates an AUTOEXEC.BAT file for you.
Page 95

You should use high speed for almost everything you do since your programs work faster on high speed. However, certain application programs have specific timing requirements for diskette access and can run only at the slower speed. See the manual for your application program to determine if this is the case.
Page 96: Entering Keyboard Commands

There are three ways to change the processor speed: 0 Run the Setup program on your Reference diskette Cl Enter a keyboard command Cl Run the ESPEED program. If you frequently use programs that require the processor to operate at low speed or require the automatic speed change when your computer is accessing a diskette, use the Setup program to change the processor speed.
Page 97: Using The Espeed Program

To enter these commands, hold down the key and press the +, -, or * key located on the numeric keypad. The speed setting remains in effect until you press the RESET button or turn off the computer, or until you change it again using the Setup program, another keyboard command, or the ESPEED program, described below.
