You'll want to do it as follows:

         dd if=3D/dev/zero of=3D/dev/hda bs=3D512 count=3D1

If ibs and obs are the same, you can just use bs instead of using both.
(The bs option sets both ibs and obs.)  You *really* want to specify
"count=3D1", or else you will overwrite your entire disk with zeros, 512
bytes at a time.  Be very careful with this command.
