I was able to do that. And the PC was able to see it and use it. When I then stick it back into the Amiga... The same thing happens. HDtoolbox sees it, will install it, will partition the drive using the SFS. But when I reboot so that I can get it mounted, the drive light comes on and stays on for ever (most of a day before I final reset it).
As stated earlier, I tried a variety of masks that are sugested in the SFS guide. That didn't seem to change things.
When I first started all of this (before the full format), I never messed with masks or transfer speeds or anything. It worked great... right up to the point of the full format!

I don't know... people have had some realy good ideas as to fix this, but I sure am having poor luck with this.
