The following example shows the proper procedure for turning the hard disk off while the computer is on. The example assumes that you have started the computer with the hard disk on and have loaded MS-DOS from the hard disk.

1.At the MS-DOS C> prompt, type A: and press Enter to log onto drive A.

2.If you want to load an application program from the hard disk, do it now. Be sure to type c : in front of the name of the program. You must do this before you turn off the hard disk. You may also want to copy any files you will be using from drive C to drive A.

3.After you log onto drive A and copy any necessary files, you can turn off the hard disk.

Note

If you are still lugged onto drive C when you turn off the hard disk, the next time you enter a command, the screen will display an error message. If this happens, turn the hard disk back on, then log onto drive A.

4.Continue running your application program, using drive A.

5.When you want to save your data on the hard disk, turn it on. Wait about ten seconds to allow the disk to reach operational speed, then enter the command for saving your data to drive C.

Resetting the Computer

You can reset the computer to reload the operating system or to restart a program. You may need to reset the computer if an error occurs and the computer does not respond to anything you type. However, resetting erases all data in the computer’s temporary memory (RAM) that you have not stored, so reset the computer only as a last resort.
