outputting nothing but zeros to the hard drive... this effectively wipes everything clean...
some call it "low-level formatting" (though that's debatable)...
an analogy:
imagine your hard disk is a beach... now imagine a tractor with a huge rake behind it...he comes to create neat lines on the beach from end to end... the truck is preparing the sand for everyone to come and write on it... that's formatting a filesystem on your drive...
now imagine the same beach where everybody's writing on the formatted sand... for some reason, a group of people decide to do nasty stuff to the sand (corruption)... like, they bring some crazy motorcycles and mess-up all the sand... eveything is so messed-up that the people have to call the tractor with the rake again... the tractor arrives, but the sand is so messed-up now that the rake isn't really getting rid of all the damage the motorcycles made... now we have a situation where the people can come to the beach and write on the sand, but the experience won't be the same as it was before the motorcycles messed-everything up...
so the people on the beach call Mr. Zero, and he arrives at the beach with a super-heavy-duty tractor and a super-heavy-duty rake behind it to get deep into the sand where the regular rake wouldn't go... he rakes the entire beach profoundly and with industrial-strength, making sure that not one square foot of sand doesn't get unturned and that any rocks or broken glass (the bikers were drinking beer) or any foreign object is completely removed... the deep tire tracks and other deep holes dissapear... that's zeroing your drive...
of course, after Mr. Zero leaves, then the regular tractor (filesystem format) can come in and prepare the sand once again, and the lines will be like new for all the people on the beach... and eveybody's happy...
