well from my days on the TechTV message board and watching the shows on that channel, there is a program that works great.
it is part of a program called BCWipe. you download the program and then install it.
then open up the jetico folder and open up the BCWipe folder and look for the BCWipePD folder.
then copy the folder contents to a dos formatted floppy.
also copy the read me files for BCWipePD, so you will know that the commands are.
then you can select the amount of times to wipe. up to 99 times.
this is a sweet program.
yes you do need to haev a floppy drive to use it, but it will wipe a hard drive and make it difficult for normal people to recover files and info from the hard drive.
the only way to recover from a multi wiping program is with a forensic program used by the DOJ and feds.

just do a google search for BCWipe and you will find it from jetico.
