  • Page 80: How Disks Store Data

    This section explains how disks work and tells you how to do the following: Use different types of diskettes and diskette drives Care for your diskettes and diskette drives Cl Insert and remove diskettes 0 Write-protect diskettes Make backup copies of your diskettes Use a single diskette drive Ll Use two diskette drives Use a hard disk drive.
  • Page 81 Because a hard disk consists of two or more platters stacked on top of one another, it has four or more sides with many more tracks per side than a diskette. (The number of tracks depends on the capacity of the hard disk. You do not need to know how many sides and tracks your hard disk has.) A disk is further divided by sectors.
  • Page 82: Types Of Diskette Drives

    Your computer uses the read/write heads in a disk drive to store and retrieve data on a disk. To write to a disk, the computer spins it in the drive to position the area on the disk where the data is to be written under the read/write head. A diskette has an exposed area where the read/write head can access it.
  • Page 83 360KB drive-With this drive, use 5 l/4-inch, double-sided, double-density, 48 TPI (tracks per inch), 360KB diskettes. (You can also use single-sided, 160KB or 180KB diskettes.) These diskettes contain 40 tracks per side, 8 or 9 sectors per track, and hold up to 360KB of information, which is approximately 150 pages of text.

  • Page 85 Keep diskettes away from dust and dirt. Small particles of dust or dirt can scratch the magnetic surface, destroy data, and ruin the read/write heads in a diskette drive. Never wipe, brush, or try to clean diskettes in any way. Keep diskettes in a moderate environment.
  • Page 86: Inserting And Removing Diskettes

    For a 5 l/4-inch diskette, it is best to write on a label before you attach it to a diskette. If you need to write on a label that is already on a 5 ‘/q-inch diskette, use only a soft-tip pen-not a ballpoint pen or a pencil.
  • Page 87 If you have a 5 ‘/+inch diskette drive, hold the diskette with the label facing up and the read/write slot leading into the drive. 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. This keeps the diskette in place and enables the read/write heads in the diskette drive to access the diskette.
  • Page 88: Write-Protecting Diskettes

    Write-protecting Diskettes You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can read it and copy data from it, but you cannot store new data on the diskette or delete any files it contains. If you try to change data stored on a write-protected diskette, MS-DOS displays an error message.
  • Page 89 Note Some program diskettes, such as your MS-DOS diskettes and your Reference diskette, have no switch so they are permanently write-protected. This protects them from being accidentally erased or altered. It is a good idea to write- protect the backup copies you make of your MS-DOS and Reference diskettes.

    Making Backup Copies It is important to make copies of all your data and system d i s k e t t e s . M a k e b a c k u p ( o r w o r k i n g ) c o p i e s contain programs, such as the original MS-DOS and Reference diskettes that come with the Equity 386SX, and use only the copies.
  • Page 91: Using A Single Diskette Drive

    Using a Single Diskette Drive MS-DOS expects the computer to have at least two diskette drives, and it displays prompts and messages accordingly. If your system has a single diskette drive, MS-DOS treats your one drive like two logical drives. This helps you perform operations that normally require two diskette drives.
  • Page 92: Using Two Diskette Drives

    Using Two Diskette Drives If you have two diskette drives, you can use the top drive (A) for loading the operating system and application programs and the second drive (B) for creating data. If you have a hard disk, you will probably need the diskette drives just to copy files to and from the hard disk and to copy diskettes.
  • Page 93 Note MS-DOS Shell program is a menu-driven program which makes it easy for you to move, create, delete, and rename files and directories, as well as view files and execute MS-DOS Shell User’s commands. See your instructions. If your Equity 386SX has a hard disk drive, follow these precautions to protect it from damage and to avoid losing data: Never turn off the computer when the hard disk drive light is on.
  • Page 94 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 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 95: Turning Off The Computer

    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. The computer locks the heads and disables the keyboard. You can now turn off the computer and prepare to move it to the new location.

  • Page 100: The Current Drive

    The Current Drive At any given time, MS-DOS considers one disk drive to be the current (or default) drive. The current drive is the drive on which MS-DOS executes your next command, unless you tell it to do otherwise. For example, if the current drive is C, and you enter the DIR (directory) command, MS-DOS lists the files stored on drive C.

  • Page 113 Directories are essential for organizing files on a hard disk, and you might even want to create directories on a 1.44MB diskette. However, you may not need to create directories if you use lower capacity diskettes-especially if the diskette contains only a few large files.
  • Page 114 This directory tree lets you separate business word processing files from personal word processing files, and sales spreadsheets from spreadsheet files used for financial projections. Your directory structure may be as simple as this example or much more complex. Organize your disk(s) to suit your needs. As your needs change, you can modify the structure by deleting old directories and creating new ones.
  • Page 115: The Current Directory

    The Current Directory MS-DOS always recognizes one directory as the current (or default) directory, just as it always recognizes one drive as the current drive. The current directory is the directory you are logged onto at the time and the one in which MS-DOS performs your commands, unless you tell it to do otherwise.
  • Page 116: Using Pathnames

    Using Pathnames You use pathnames with MS-DOS commands to tell MS-DOS how to find its way to the directory you want to access. Backslashes separate the directories in a pathname. There are two types of pathnames: absolute and relative. An absolute pathname begins with a backslash and tells MS-DOS how to find its way to the desired directory from the root directory.
  • Page 117: Including Filenames With Pathnames

    You can use either relative or absolute pathnames at any time, as long as you give MS-DOS enough information to find the directory or file at the end of the pathname. Including Filenames With Pathnames You can use a pathname when you want to access a file that is not in the current directory.
