Just a word of caution - only do this is you want to wipe out the
partition table, as well as clear the mbr. I think using bs=492 will
clear the mbr wile leaving the partition table. (I could have the
number wrong.) This is handy if you need to preserve smaller
partition sizes when you do a restore.

The number is 496 if you want only the load code to be voided. The parm count=1 is for zapping only the first track with mbr. For the partition table use bs=1 count=66 skip 466

... sorry, wrong typing; the corret block size is 466 and not 496. I apologize.
