I spent a while googling this, but found nothing. It just now occurred to me that i could: 1) slave the drive in a win (or nix) pc 2) reformat to respective filesystem 3) then wipe using that filesystem's "eraser" app. system is g3, 10gb ata hdd. If this doesn't work (?!), then I'll post/edit this thread. Otherwise, maybe someone in future will find this "solution" useful.
