you cant use wb 2.05 as that requires kickstart 2.x or higher.
and as far as hdtoolbox goes, u cant use that either, what u need is the floppies that came with your hdd (the GVP) , normally theese are self installing ones, ie just insert the floppy and make it boot, then it should prep the hdd, its too long ago for me to remeber everything in detail sadly, but check your hdd software closer.
