n the case of multiple hard drives, you have the option of whether to do them all at once, or one at a time. Generally I scan/defrag C D E and F drives at the same time, and the C drive by itself after a major crash, install/uninstall or CD burning session (where I free up a lot of space on the C drive after deleting).

Notes:
* External modem (cable, DSL) users can simply unplug the power to the modem.
** However, do not do this until you have made sure you are not connected to the net.
*** To start your computer in Safe Mode: Restart the computer. As the computer restarts, press and hold down the F8 key until the Windows 98 startup menu appears. Choose Safe mode from the startup menu, and then press Enter. Windows starts in Safe mode. Note: For Win98 Users only.
