data on the hard drive. Warning messages usually interrupt the task and require you to respond by typing
y (yes) or n (no).
NOTE: Warning messages are generated by either the application or the operating system. For more
information, see the documentation that accompanied the operating system or application.

The system diagnostic utilities may issue messages if you run diagnostic tests on your system. For more
