If you have not already done so, copy the HDSIT.COM and HDSIT.VER files from the Reference diskette to your hard disk. Then, when you want to run HDSIT, log onto the directory where these files are stored. Type HDSIT and press (br*rl.

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 then locks the heads and disables the keyboard. Remove any diskettes and turn off the computer. Now you can move it to the new location.

Caution

Whether you use HDSIT or not, always turn off your computer and wait at least 20 seconds before you move it. This allows your hard disk drive’s read/write heads to move away from the disk to a safe location. If you move your computer before this happens, you could damage your hard disk drives.

Using AUTOEXEC.BAT and Other Batch Files

If you are using MS-DOS to access your application programs, you may find that there are commands 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.

If you have a word processing program that can save a file as a text only file (sometimes called an ASCII file), you can use it to create a batch file. You can also use the MS-DOS COPY, EDIT, or EDLIN command, or a text editor, to create the file.
