Well now it seems #OpenBSD has me beat when trying to wipe and setup a new USB memory stick.
I have never had issues under FreeBSD or Linux before but this is either me being extremely thick or ??

I used dd to wipe the USB then checked it was wiped. Then did the above and it all seems ok as per folk on the web and OpenBSD docs but newfs_extfs just sits there doing nothing.

Anyone help or have a simple idiot sheet of what to do from wiping the USB memory stick to setting up an ext2 partition and formatting it. Mounting it will be the easy part.
