When you want to remove the diskette, make sure the drive
light is off; then press the release button. Remove the diskette
and store it properly.
Caution
Never remove a diskette, reset the computer, or turn it off
while a diskette drive light is on. You could lose data. Also,
remove all diskettes before you turn off the computer.
Stopping a Command or Program
You may sometimes need to stop a command or program while
it is running. If you want to stop a DOS command or a DOS
application program command, try one of the following from
the DOS prompt:
0 Press Pause
0 Press Ctrl C
0 Press Ctrl Break.
If you are using Windows, press Ctrl Alt Del and follow the
instructions on the screen.
If these methods do not work, you may need to reset the
computer as described below. Do not turn off the computer to
exit a program or stop a command unless you have to, because
the computer erases any data you did not save.
