a good thing would be to look at your syscheck
How to post a syscheck: Instructions here
but i guess you just want to get it all up and running.
You could use the softmod any wii guide by mauifrog (linked below) and stop doing this and that and theese without knowing (i guess, sorry if I am wrong) what you are doing it will give you the perfect setup which you need to play any game, has options to go for, in your case maybe you want to update via the guide to 4.1. it has the most shortcuts available and you will be done in less than 20 minutes and are perfectly set.
just read through the guide thoroughly, takes some time but you wont regret the outcome of it.
for the harddrive, maybe it is not compatible, you can try again with a fat32 route, also any usb stick/thumbdrive should work to test your modding. fat32 guide linked below as well.
good luck for now
