Format (to erase a hard drive) 
Format is a command that prepares 
a blank diskette, hard drive, or 
another drive to hold data. If the 
disk or drive already contains 
information, all information on 
it would be erased. For example, 
if you wanted to wipe everything 
on your hard drive, typing 
"format C:" would effectively erase 
all data on your computer, including 
the operating system (e.g., Windows).
