if u want to perform only a formatting then cd is not reqired.by using a windows startup floppy u can format the hdd.one thing copy format.com to the floppy.because by default format command will not be there in floppy
LOL!!! I think it's funny that you told the guy that you "definitely don't need the CD's to reformat your hard drive" and then you ask the question "what is reformatting"?? LOL
If you've formated your hard drive once and you plan to format it again then you are reformating. Just means that you are doing it again.
