    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 hard (3.5-inch diskette) or slightly flexible (5.25-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.

If your hard disk drive does not do this, or if you are not sure that it does, be sure to run HDSIT.
  • Page 42: Using Autoexec.bat And Other Batch Files

    Using AUTOEXEC.BAT and Other Batch Files If you are using MS-DOS to access your application programs, you may find that there are co mmands you need to run frequently. You can automate the execution of these commands by listing them in a special file called a batch file. When you type the name of the batch file and press m, MS-DOS executes the commands in the file just as if you had typed each command from the keyboard.
