i have prolly used disk utility about 3 times to format my 3g ipod so as to keep it clean for those ipod updates that have come out every now and then.. question is.. does using the "write random zero" option in disk utility put too much stress on the ipod? does it harm it in ne way? i only choose it as to wipe out the ipod then reinstall the updator software.. then resync.. so does it cause hardware probs? or is it nothing to worry about?
