Got everything sorted. Thanks all !!
Mike- I could see it in workbench and open folders but couldn't get Dopus to select it. Turns out it was user error (like always), I had misconfigured my emulator.
I think the scsi.device can handle up to 8 gigs without problems. It just doesn't keep the correct size after 4 gigs (wraps around) but it still works. If I'm wrong let me know
