xRavenx, I'm not too sure about the F drive vs E drive issues, but I do know from experience that the G drive issues are directly linked to what cluster size you format it with. If you use XBPartitioner, then you know that unless you manually change it, it automatically adjusts the cluster size (32bit, 64, 128, etc) to the size of your partition. When I first formatted my 750gig drive, I split it right down the middle between F & G, and XMugen wouldn't work on either partition. Once I reformatted with the F with 129gigs (the original limit) and the rest to G, XMugen will work on F, but not on G. Hope that helps.
