I have never tested xamiga, but perhaps it could be some clue. If a drawer is mounted in uae I have noticed that the size of partition comes up wrong.
When this have happened to me I have had a drawer on an SFS partition that was mounted as work. This SFS partition was 8gb. But when I look at this from within UAE it says work (the drawer mounted) is an FFS partition. And if I remember right FFS will be problem over 1gb. Can it be that UAE gets the SFS size?? and can't handle it?
I would test this by create a hardfile thats 500mb and attach it by altering the config for uae. Then again I don't know if this is accessible from xamiga.
EDIT. I realize that this was not much of a help. Hope someone else have a better answer.
