On my Windows XP Pro I installed WBFS Manager. I inserted a 2GB Pen Drive and formatted it with WBFS Manager to WBFS format, I copied a couple isos onto it with the Manager app and it worked.
I have a 3.4U Wii with cIOS rev 10 and SD/USB 1.5 Loader installed. Now it sees the pen drive, but it says it is not formatted. If I try to format it, it says it can't find a partition. But I don't need to add a partition to the pen drive because it already had one, or at least that is what I would assume happened when I was able to format it WBFS through the manager app. Which is a very cool well written app.
So I just downloaded the Mac manager because my Windows machine is off.
Anyway, I attached my Pen Drive and it still is good, I see the two isos I created. So I wonder what is wrong on the Wii and USB Loader that it isn't seeing it.
Thanks
