Problem USB Loader (WD Scorpio Blue)

Hi, my name is Ju.
How are you guys?
I've bought a Western Digital - 500GB - Scorpio Blue (500ma). But my USB port is not working right.
Am I going though a incompatibility problem?
Did someone have this same issue before?
I'm trying everything in here!

I already formatted the HD to WBFS. All the games are there.
But is not mounting.. :-(

Are you using USB loader?

That drive is listed as compatible. You have to provide more details if you want some help. What loader and version are you using, what guide did you use to mod, etc.
