first of all, if i post this in the wrong section of the forum, im sorry....... thought this is part of the hardware section 
anyways recently my computer has been developing bad sectors, and it's out of control, tried to reformat with the recovery cd that came with computer, doesnt help at all. and my friend told me about low level format, i went online and did some research, and i just got more confused. there's zero-fill and low level format, i just don't know which one to use, and what are the disadventages of using them.
glad to have any suggestions
