If you cannot use Microsoft Windows to do the job, use a Linux distro, you can boot a wide selection of Linux distros from a USB

That's an absolute joke, If the HDD isn't easily reformatable Nintendo screwed up. I'll give it a go on windows first then followed by linux and post my findings here.

I had no trouble reformatting my drive in OSX. Don't know about Windows systems, but it might be something wierd that is specific to your setup.
