file system corruption does the 30gig senario
auto nuke should only work if you have only one drive in the computer; otherwise you will need to do the manual version
I suggest (do this myself
>>>> been biten before) you pull the power plugs from any drives you DONT want wiped
this process is slooooooowwwwwww about one hour to wipe per 20 gig of drive space
keep us posted on your progress
