Disk Wiping Utilities

[Dan Williamson]

I am looking for a good utility to erase all hard drives 
in a machine to a DOD standard. I would prefer a 
FREE utility as this is a government agency and I try 
to keep costs down.

I have read that Norton Wipeinfo, BCWipe and 
several other programs wipe only the known 
partitions. I need a tool that will wipe EVERYTHING !

TIA
Dan
