The way to wipe everything. Everything. EVERYTHING! EVERY SINGLE THING!!!!!! Well, a format can easily enough wipe out everything and reset the computer into factory settings. What I mean by factory settings is the plain, nothing computer with everything on default settings. And I mean it. Default resolution, default setting, default everything. Disk and Disk :E and other disks will also have to be formatted, but NOT FROM THE CD, unless you want to change by having Disk :C and only. It's the use.
Formatting is used for re-installing the PC, such as re-installing Win-7, Win-8, Or Win-XP. It needs a CD. Prepare a back-up if you want certain files to live. Once you click the button, it's all over. The computer is gone! If you want to wipe-out everything but with the same OS you use, just use the CD to delete :C and make new Raw Disk :C and install it with your OS. My OS is Win-XP, and this has occurred when my files are infected. Virus? Win32\Chir\B@mm
