After reading the rest of your posts, I'll assume you at least have GVP's Faaastprep utility on hand. It's simple to use and does a little more than HDToolBox does.
If you don't have that, find a copy of HDToolBox on your original disks and either change the scsi.device tooltype to gvpscsi.device or start HDToolBox from a command line with gvpscsi.device as a parameter.
IE:> hdtoolbox gvpscsi.device
should do the trick.
